DM002 5.8G FPV Review

The flights in FPV, it is no longer reserved to a fortunate elite and able to fly in wide spaces. The piloting in immersion, it is possible with a device that costs a little more than 40 €. This is the case of the DM002, a nano multirotor of fairly standard invoice, fully equipped to be ready to fly at its exit from the box. It is delivered assembled, with its brushed motors (fixed with connectors (therefore easy to change) and its Hubsan X4 type propellers, a flight controller which is not documented in the data sheet It is supplied with a camera combo 600TVL and a 5.8 GHz 40-channel video transmitter including the ImmersionRC Raceband with a power of 25 mW, 80 mW or 200 mW (only 25 mW are allowed in Europe).

The battery is a Lipo 1S 3.7V of 300 mAh which ensures about 7 minutes of flight. The 2.4 GHz radio receiver is proprietary, associated with a radio remote control in mode 2 only. A basic machine which, if it is sufficiently motorized, can constitute an excellent multirotor to begin the piloting in immersion, at home in indoor. It will be proposed for about 42 € at Banggood (with the port but without taxes), in white or in black. To fly in immersion, it is nevertheless necessary to add a device of reception and viewing of the images in real time. To stay in a floor price, you can opt for the Eachine VR007 mask, at just over € 45. It's not great, but enough to get started! What makes a complete FPV solution for less than 90 €! Not bad ... Warning, there is also a wifi version of the DM002: it is to avoid for the flights in immersion because of a latency too important.

Cornet: musical instrument and its features

Cornet - Musical instrument made of copper, is part of the brass band. This is a direct descendant of the post horn. The latter has a rich history. The Jewish priests blew him to the walls of Jericho fell down. 

History 

Modern cornet trumpet made of copper and its predecessors made of wood. The German name of a musical instrument - zinc. In the 15-17 th centuries, this gimmick has been very common in Europe. Cornet - Musical instrument, without which it is impossible to perform many works of the classics. It is mandatory participant in city festivals Renaissance. Solo on this tool have been distributed in Italy in the 16th century. To have survived the names of famous virtuosos of the era - Claudio Monteverdi and Giovanni Bossano. 

The position and the present

Cornet - Musical instrument, which gradually began to lose ground in the 17th century, after the spread of violin playing. The longest he has maintained a dominant position in northern Europe. There is recent solo works have been dated to the eighteenth century. Cornet - Musical instrument, which completely lost relevance in the 19 st century. Now it is used in the performance of old folk music. Later, there were more modern keyboards, wind instruments. In particular, the cornet-a-piston was created in 1830 in Paris. Sigismund Shteltselya believe his father-inventor. This tool is equipped with a pair of valves. 

flowering 

In 1869, keyboard-wind instruments, in particular the updated cornet, are widely distributed, and begins active learning the game to them. They began their work specific courses at the Paris Conservatoire. Jean Baptiste Arban was at the forefront of this process. This is the first professor, and cornet virtuoso of his craft. At the end of the 19th century came the peak of the popularity of the instrument. At this time, he came into the Russian Empire. 

Nikolai Pavlovich - the first Russian tsar, who played at the same time on various types of well-known at the time of wind instruments. He spoke beautifully and with this tool, both with its outdated design and modern. Contemporaries referred to the outstanding abilities of the king in the field of music. He even composed his own works, as a rule, military marches. King demonstrated their achievements within the framework of chamber concerts. It was made in his time. Concerts were held in the halls of the Winter Palace. Extra people, as a rule, they were not. The king lacked the time and opportunity to make music on a regular basis, for this reason, he ordered the author of the hymn AF Lvov to come to a rehearsal before the performance. Especially for Nicholas, his teacher was a party for Cornet.

The literature often mentions we are interested in a musical instrument. In particular in the works of "Gloomy Morning" by A. Tolstoy, "Sakhalin Island" by Chekhov, "audience" Gorky. The secret of this success lies in the superiority of this instrument over the other in the performance of brass music, which required greater fluency. Cornet different mobility enormous technical and expressive and bright tone. This tool allows you to "draw" the listener tune the product.

Scottish musical instruments that we know except the bagpipes?

When it comes to Scotland, then immediately come to mind men in plaid wool skirts, gloomy mountains, moorlands, piercing icy wind, strong whiskey and, of course, loud and sonorous pipes. Alone it is annoying, disturbing and making trouble in the soul, to others it sounds reminiscent of something elusive, but very close, native. For the Scots themselves sound of bagpipes - echoes of history, the past, the connection with the roots, which is not lost through the ages, and becomes stronger with each new generation. For a simple layman consistently one - Scottish bagpipes leaves no one indifferent. 

Scottish bagpipe 

Bagpipes - The most popular and iconic element of Scotland. Although she is not a native Scottish musical instrument (bagpipe was brought by the Vikings), it is this "bag with tubes," praised Scotland on a par with the kilt. Like all Scottish music instruments, bagpipe created from scrap materials. Most often it is made of goat or sheep skin turned inside out. Because the skin makes a kind of bag, which is tightly sutured with inserted in it with five tubes. After one upper air is supplied to the bagpipes. On the bottom there are holes to change the sounds. Three top those same sounds and publish. 

At the sounding pipes is not like any one musical instrument. Maybe that's what makes it so unique. In the old days, each clan had its own piper, who accompanied all celebrations, events and campaigns leader. Medieval Scottish bagpipers reproduced lingering melodies with hardly perceptible form. This kind of music still carries the name Pibroh (Piobaireachd) and today is a textbook material written specifically for the Scottish bagpipe.

Through the Ages 

Do not we all know, but the Scottish musical instruments are not limited to a bagpipe. This tool is a more popular and publicized more often used on national holidays. It is logical to assume that the population of this region has devised and other musical instruments, not only raises the morale in the battle, but also has alarm and entertainment properties. 

carnyx 

Suffice rare Scottish folk instrument - it carnyx. Now it is unfortunately not play. The last time he sang almost 2000 years ago. Now the artifacts found by archaeologists, are stored in the National Museum of Scotland. Carnyx as bagpipes, has a very melodic sound. But if bagpipe sometimes irritates his "squeaky", then carnyx has a very gentle, velvety sound. It is also sad, but it heard the noise of the wind, lives in the mountains of the Highlands, the smell of the fire and taste the salty North Sea. Just like bagpipes, carnyx was made from natural materials, rather antler. Its main purpose was the supply of military signal. 

whistle 

Another Scottish wind musical instrument - whistle. In appearance, and in its sound, more like a flute. The time frame of its origin is not exactly known. He seemed always. Unlike carnyx, whistle still in use today. He especially loved the Irish folklore. Whistle - very distinctive Scottish musical instrument. Its name means "tin whistle".

Wind Instruments: the list of names

Almost all bands present wind musical instruments. List of them will be given in this article. Also, it contains information about the kinds of wind instruments and extraction principle are sound. 

winds 

This pipe, which can be made of wood, metal or any other material. They have a different shape and tonally emit different musical sounds, are extracted by means of air flow. The timbre of the "voice" of wind instrument depends on its size. What it is, the more air passes through it, causing the frequency of its oscillation less and emitted sound - low.

There are two ways to change the pitch, published a tool of this type: air volume control fingers using scenes, valves, vents, and so forth, depending on the type of instrument; increasing the injection force of the air column in the pipe. The sound is completely dependent on the flow of air, hence the name - wind instruments. List of them will be given below. 

Variations Woodwind 

There are two main types - brass and wood. Initially, they were classified so depending on what material is made of. Now more type of tool depends on the manner in which the sound is extracted from it. For example, the flute is considered woodwind. Thus it can be made of wood, metal or glass. The saxophone has always produced only metal, but is classified as a woodwind. Copper tools can be made of various metals: copper, silver, brass, and so on. There is a special kind - wind instruments keyboards. List of them is not so great. These include a harmonium, organ, accordion, melodica, accordion. The air is supplied to them through special bellows. 

Brass 

Wind brass musical instruments, as mentioned above, made of different metals, although in the Middle Ages, there were those who were made of wood. Sound is extracted from them by strengthening or weakening the injected air, and by changing the position of the lips of the musician. Initially brass reproduced only natural scale. In the 30s of the 19th century they were valves. This has allowed such instruments play a chromatic scale. In trombone for this purpose is a pull-out scenes.

Unmanned aerial vehicles. Features drones

In the view of most people, not related to aviation, unmanned aerial vehicles are more sophisticated version of the radio-controlled model airplanes. In a sense, the way it is. However, the functions of these devices in recent years have become so diverse that only a limited view of this they can not anymore. 

Home unmanned era

If we talk about automatic aerial and space remote-controlled systems, the theme is not new. Another thing is that in the last decade they appeared certain fashion. At its core, the Soviet shuttle "Buran", made space flight without the crew and landed safely in the now distant 1988 - the same drone. Photos of Venus' surface and many of the scientific data on this planet (1965) also obtained in an automatic and telemetry mode. And the rovers are consistent with notions of unmanned technology. And many other achievements of Soviet science in the space sector. Whence came the said fashion? Apparently, it was the result of the experience of combat use of such equipment, and he was rich. 

Initially, unmanned aerial vehicles most often used either as a training target, or as flying bombs. It was in the first third of the XX century, and this position is maintained until the end of the century (not counting the spacecraft). Air losses in the Vietnam War forced the Pentagon leadership to think about how to reduce casualties. The same considerations prompted to start developing managed to land aviation means designers Israeli firms. 

Classification of UAVs 

At the initial stage of development of this class Aerotechnica drones were unmanageable. The technological revolution and software development gave rise to the creation of flying robots working for a given algorithm. In other words, such a device should then start to fly on a given route at the correct height, lock on built-in electronic recording equipment information on the ground under the wing of the situation, to come back to the starting point and landing. The variant of broadcasting data in real time on the monitor receiver over the air, but only for raid process control personnel located in the tracking point does not interfere. For all the merits of this approach, it has a significant flaw. Create a program that would take into account all possible situations, it is impossible. Then there was a third way of solving managerial functions - telemetry. The pilot is on the ground, watching the situation through the built-in cameras, is recording the necessary information and make decisions as well as a pilot conventional aircraft. This method is called remotely-piloted. He, incidentally, is used in toys, radio control models, however, quite expensive (they cost hundreds and sometimes thousands of dollars). 

Experience in the use of new technology has received the Israel Defense Forces (IDF) during the 1973 war. Unmanned aerial vehicles used for operational intelligence, but the large size and weight of the video equipment at the time limited the possibilities of this tool. Nevertheless, it is in the Middle Eastern country before anyone realized the prospect of remote-controlled aircraft, which also affected the future success of Israeli designers.

Patterns soft cats can be very different. There are simple and complex options. In terms of form objects are: flat as a carpet; poluobemnyh; volume. On a functional purpose fabric cats made as soft toys; cushions; gifts and decor; large interior objects. From the point of view of manufacturing techniques can cause a classification: monoobektnye or simplified when the fabric is cut from two parts which are stitched through the complex contour; combined or complex, in which the legs are sewn separately, head, tail, and then it's going into a whole.

The materials used 

Below we will see how the cats are sewn by hand. Patterns shown in the illustrations, suitable for all kinds of fabrics. The choice is determined by what you want to create and what kind of effect you want to get. You can make a toy out of scraps that you are available to buy fabric or specially. In the second case, the outcome of decoration, surface texture, quality and cost of the fabric.

Walkera Rodeo F110 Review

The Rodeo F150 from Walkera had liked us (see the test here), here is his little brother Rodeo F110. A small format machine as it measures 10.1 x 11.7 x 5.5 cm for a weight of 101 grams (without battery). The data sheet does not indicate the characteristics of the brushless motors or the ESC, but the flight controller is a SP Racing F3.

For immersion

The FPV camera is a 600TVL associated with a 5.8 GHz 40 channel video transmitter including the 25 mW ImmersionRC Raceband. The battery is a Lipo 2S 7.4V of 850 mAh and 25C for a range of 7 to 8 minutes according to the manufacturer. The 2.4 GHz radio receiver is compatible with Devo radio controls. Moreover, the device is offered in pack RTF with a Devo 7, or in BnF without this radio control. It will be available at Banggood from 150 € (with the port but without taxes).

Additionally, if you need to purchase some rc drone parts, you can search via Banggood website, which is one of the wholesale platform to provide affordable prices, such as futaba controller, 3dr telemetry driver, etc. 

FrSky XMPF3E Review

The XMPF3E, an SP Racing F3 flight controller with accelerometer, gyroscope, electronic compass and altimeter barometer with a 2.4 GHz radio receiver compatible with the Taranis X9D / X9E protocol and Horus X12S / XJT In D16 mode. It measures 3.6 x 3.6 cm for a weight of 7 grams. Too bad, the card is limited to these two functions (flight controller and radio receiver), there is no PDB, no current sensor, no OSD ... More surprising on the part of FrSky, the card is Unidirectional, without telemetry. Bizarre - maybe a more advanced version will be offered later. The XMPF3E of FrSky is proposed to 33 € with Banggood (with the port but without taxes).

Additionally, if you need to purchase some rc drone parts, you can search via Banggood website, which is one of the wholesale platform to provide affordable prices, such as 1300mah lipo battery, 325mm blades, etc. 

Eachine E010C Review

The fashion of the Tiny Whoop, you win! Even entry-level models are no longer "ready for immersion". That is to say the presence of a camera combo-video transmitter 5.8 GHz. This is the case with Everyine's E010C, which relies on the classic E010. What we do not know is whether the engines were changed for a little more power. The battery, in any case, is a little more efficient than that of Tiny Whoop batteries, which gives hope that the 45C of the supplied battery can be expressed during the flight. The camera is an 800TVL associated with a transmitter 5.8 GHz of 25 mW and 40 channels. The device offers "headless" functions, RTH ... which do not really interest in immersion.

Strengths, weaknesses

Eachine-e010c-04The weak points of this device? Probably its radio remote control too small to be nice, although it is available in mode 1 and mode 2, and the transmitter antenna, effective but fragile. The strong points ? The fact that the device is ready for use and to fly in immersion. The price, too, of course, since it will be offered at a little more than 35 € at Banggood (with the port but without taxes), dressed in green or red. Who is this device for? If you drive in FPV with goggles or a mask, you have children, this small investment allows you to introduce your kids with a ready-to-use, risk-free device for an ultra-light price (always under surveillance) An adult, of course).

Drones against urban planning fraud?

It seems that our policies are bored when there is not a primary to get under their teeth. Then they turn to the drones. Caricature? A little. Jean-Louis Masson, senator of the Moselle, asked the following written question in the Senate (No. 24146): "Mr. Jean Louis Masson asks the Minister of the Interior if a commune can use a drone to proceed Checks on private property, in particular, to identify possible infringements of urban planning rules or failure to declare the creation of swimming pools in order to calculate the local tax base ". That was on December 1, 2016.

Can it, the commune?

The answer is very complex, it would require the work of a lawyer to address all the regulatory issues that this practice raises. A municipality is subject to the texts of 1 January 2016. It is also possible to exempt civilian drones from safety rules such as theft over persons without a security perimeter may be justified in the case of a rescue mission or maintenance of order , It is hardly defensible in the case of a verification flight. The Prefect may distribute derogations, but they relate only to "relief, rescue and civil protection missions". Only military aircraft and aircraft of the State, chartered or leased by it and used in the context of relief, rescue, customs, police or civil security missions may evolve in derogation from the provisions of this Order When the circumstances of the mission and the requirements of public order and security justify it ". It is not about rescue, rescue, customs, or civil security. Remains a police action. Now the mayor is a judicial police officer!

It is likely that

Where complications arise, mayors are obliged to have a violation of urban planning rules brought to their attention by drawing up a report to be transmitted to the Public Prosecutor. The breach exposes them to savage sanctions. Are we going to see drones monitoring the progress of work by private individuals to check if they are in compliance with the permits that have been issued? Perhaps. And privacy in this? The respect of privacy is obviously concerned by a video surveillance type, which involves a photo or video capture and storage for study. It is the CNIL that will be competent to issue an opinion, relying mainly on the law of data processing and freedoms of 6 January 1978 as amended by the law of 6 August 2004, A supervision of individuals practiced (or not) in the course of a police mission. It is complicated ? Wait patiently for the response of the Ministry of the Interior ...

DJI Inspire 2: redundancy and front camera

The Inspire 1 is used by many professionals to make efficient flights without having to deploy a large format machine. The new version was much awaited. What's new ? The main structure, made of magnesium alloy and aluminum, has been reinforced, assures DJI. The aircraft is now capable of reaching 108 km / h. Not bad to go quickly on the spot to film, then come back as fast. Autonomy is estimated at 27 minutes. It is provided by a system of two independent and heated batteries. It is possible to leave with two batteries for a complete autonomy and a redundancy in case of worry with one of the two. DJI ensures that flights are possible up to temperatures of -20 ° C!

The keyword: redundancy!

Dji-inspire-two-02-1200Inspire 2 also flies with a single battery, but shorter and without taking advantage of redundancy. Component redundancy also includes GPS, altimeter barometer, and ESC. The aircraft can fly up to an altitude of 5000 meters - let us understand, it does not mean that it can fly from the ground up to 5000 meters, DJI simply guarantees that its sensors, notably the altimeter barometer, Lifting power ensures its smooth operation up to 5000 meters. Obstacle detection and avoidance tools have been integrated into the Inspire 2: Stereo cameras are placed at the front and at the bottom, complemented by infrared sensors on top. This improves flight safety during tricky maneuvers, especially when passing in front of, on and under obstacles.

Everything for the video!

Dji-inspire-deux-05-1200New that the pilots will love: at the front of the Inspire 2 there is a non-stabilized 2-axis camera (pitch and roll, with the pitch controllable from 0 to 60 °) Control the device. The main video camera stabilized by a nacelle is therefore entirely intended for the cameraman to concentrate on the capture of the images. At the core of image processing is CineCore 2.0. It is a built-in chassis tool that handles heavy computations to facilitate the storage of video files. It adapts to the camera that is placed on the Inspire 2. The fact that it is no longer in the camera makes it lighter and easier to mount. The videos are stored in 5.2K / 30 frames per second at 4.2 Gb / s, in CinemaDNG on SSD media.

Two new stabilized cameras

Dji-xquatres-02-1200Inspire 2 can accommodate two new stabilized cameras. The first is the Zenmuse X4S offers a 1-inch, 20-megapixel sensor with a dynamic range of 11.6 stops, with a focal length of 24 mm. This entry level camera can be replaced by the Zenmuse X5S, which relies on a sensor in Micro 4/3 format. It covers a dynamic range of 12.8 stops and opens up to F / 1.7. She also films in 5.2K / 30 and 4K / 30 in format Apple ProRes2. Or in 4K / 60 frames per second in H / 264. Or in 4K / 30 in H.265. The sensor is a 20.8 megapixel.

Dji-xcinqs-01-1200The rotation of the camera at 360 ° is no longer possible was already limited to 320 ° on the Inspire 1, but the Inspire 2 allows compensates by a soft rotation on the yaw, stabilized by the 3rd Axis of the camera. All settings, including focus, are made from the DJI GO application. The image of the stabilized camera is transmitted in long distance (4 km) via Lightbridge technology in 1080i / 50 and 720p / 60.

DJI Phantom 4 Pro: radio remote control, obstacles and 4K / 60

The DJI Phantom 4, best-selling in multi-shot models for shooting, is back in an improved version. What's new in the program? The Phantom 4 Pro is the first multirotor intended for the general public (despite its name "pro") capable of filming in 4K and at 60 frames per second, instead of the classical 30 or 24 images by second. If you tried to shoot a panorama by rapidly rotating the camera on itself, in 4K / 24, you know that you get a very jerky video, unpleasant for the viewer. With a frame rate of 60 frames per second, the image is streamlined for optimum results on a 4K TV. The bit rate, in terms of data, is 100 Mb / s - it will take quality memory cards to hold the shock. The sensor of the Phantom 4 Pro is a 1-inch 20-megapixel 12-stops, which should satisfy the photographers ...

Detection in all directions

Dji-phantom-four-pro-02-1200 The detection and avoidance of obstacles recently introduced in the Phantom range only concerned what was at the front of the aircraft. The Phantom 4 Pro is now equipped with 3 stereo cameras. One is in front, the other behind and the third under the camera. They allow to create a 3D model of the environment to improve the detection and propose the avoidance. Infrared sensors on both sides complete the Phantom 4's security solution. An impressive device, coupled with the FlightAutonomy module, which now allows you to fly without fear of backing up and hitting an obstacle - you will obviously have to put the system to the test , Particularly that of thin branches of trees. Only obstacles above the unit will not be detected. DJI ensures that avoidance works up to 50 km / h! The Sport mode allows it to reach 72 km / h, but without detection of obstacles.

And…

Dji-phantom-four-pro-07-1200The Phantom 4 Pro comes with a new radio control, more compact than the previous models, which operates in 2.4 or 5.8 GHz (depending on the radio environment ). It's also equipped with a GPS receiver to manage the return to the starting point and tracking, a port for a microSD memory card and an HDMI port to broadcast the video feedback signal in (It needed an accessory on previous models). It can accommodate (optional) the Crystalsky screen to display video feedback and telemetry data. Edit: It seems that the HDMI port is only available on the GL300F version, which comes with the Crystalsky screen. The GL300E version without a display (for smartphones and tablets) does not have an HDMI connector.

On the software side?

Dji-phantom-four-pro-03-1200DJI GO is enriched with a "Draw" function: it draws the itinerary of the Phantom 4 Pro to the screen, and it follows it ... "Narrow Sensing" allows to fly in a Environment, between obstacles, without risking the fatal touch. There are always "ActiveTrack" functions for tracking people and objects, "Profile" and "Spotlight" which have been enriched with the detection of obstacles in all directions. "TapFly", which controls the Phantom 4 by touching a target point on the screen, gains modes to steal camera towards you, so camera facing back, and with a free orientation to point the camera at will during the flight. Finally, the "AR Route" function displays the flight path in the form of a dotted line on the screen to better manage the positioning of the camera. The price of the Phantom 4 Pro is 1699 €.

JJRC H20W in Spanish: A mini drone with FPV WIFI camera

The drones with FPV camera for WiFi are not exactly to my liking as a rule. When the real time image of the camera of a drone reaches you via WiFi, it usually gives many problems in the lower price ranges of this hobby (interference, exaggerated delay in the image, very blurry ...) but with this JJRC H20W I have to Recognize that I have been impressed with what it offers. Let's go with the review.

We can not be confused: the JJRC H20W is not a normal JJRC H20 with FPV camera. They are drones that aesthetically have made them very similar but that in the rest they do not resemble at all: in size, flight style, control .. Nothing. We are facing a drone much closer to the range of mini drones (a bigger palm of a hand) whose references are the Hubsan X4 h107, Syma X11, JJRC H6C ... things like that.

On the other hand, and leaving the FPV and recording the camera for the end, we have to emphasize greatly its great resistance to the wind. We are facing a drone that knows how to fight wind gusts of 20km / h, which for a drone of this type has a lot of merit. It is a pleasure to see how JJRC strives every day to make drones that can with this type of unforeseen, since it is of the most important in this range to improve these points.

As for normal flight, we are facing a really stable drone if you like but also with a very fast one. We can get to complete circuits fairly fast compared to the price and strength of this drone, which leaves hallucinated many times. It may be that its higher speed mode is very unstable and especially fast in the beginning, but once mastered ... will be one of the greatest pleasures in flying this drone.

Regarding the range, make it clear that it is not a drone to move it beyond 20 or 30 meters, since we can not control it with the view and it starts to give dots of sporadic signal loss. It is not a very bad thing, but I would not take it beyond those distances, which is when the eye starts not to distinguish well the nose of the drone's ass). About its autonomy, we are before the 6 minutes or 7 long, depending on how you fly and such, but how we can exchange their batteries ... I think it is something very interesting and positive for this drone.

On your FPV, say that we are not before one that goes by the frequency of 5.8 gHz (which is the most normal and recommended to watch the video in real time) but if it perfectly achieves its goal: to be able to control the drone from the screen . We may sometimes find ourselves in greater delays, it may, but that is not the norm, seeing in real time a great caldiad of video that will allow us to recognize the terrain perfectly.

Another theme is how you record the drone's camera to see it in your house. A very bad video quality that will hardly serve to make small assemblies or things like that. Low definition, very moved, deformations and too saturated colors ... Come on, let alone the format, which is not exactly too friendly.

In short, this is a very interesting drone and if you are convinced by the concepts I mentioned in the article you should go head over it, since the price, to this day, is not too bad.

ELECTROACOUSTIC GUITAR: INSTRUMENT UNIT, BASIC ERRORS AND BUYING

Electroacoustic guitar is not different from its non-electrical relatives except a loud pop sound. Conventional acoustic guitars and classical, and Western-style sound is too quiet, even to speak with them in a small cafe. The first time this problem was solved by inserting into the cavity of a small microphone guitar. The sound quality was not so hot, but the musician heard the whole room. As technology sound "clean", and on the music scene, a new high-grade instrument - guitar electroacoustic.

Classification 

The guitars of this subspecies is traditionally divided into two types: "classic" (nylon strings, soft and muffled sound) and "Western" (strings of iron, sound sharp and ringing). Qualitative differences in them no - it is entirely a matter of taste. On the classical guitar playing classical music and flamenco, and the "western" (otherwise it is called "Dreadnought") - rock, country, blues, etc., in other words, everything.

Also it is necessary to dispel one very well-known fallacy. Some players confuse poluakustiku and electro. Common among these are almost no tools. They have a different sound, different roles in different composition and playing technique. Listen fire hit Seven Nation Army. This song is completely recorded on acoustic-electric guitars. Is it similar to the melodic trills conventional acoustic?

Device 

Before turning to the topic of choice and purchase of a guitar, you should start to deal with its device. Guitar electro-acoustic model of your device is very similar to an electric guitar. So, the musician touches chord ... and here begins a long while and instant way of musical notes from the instrument to the ears of the listeners. Piezoelectric transducer immediately catches the string vibrations and converts them into an electrical signal. It can be made from various materials and be in different places, but the role it always the same. Then, the preamplifier (aka preamp) grabs a damped piezo signal, amplifies it and transmits to the outside world (eg, combo amp). Located preamp, usually directly in the shell. Equalization is located in one nest with a preamplifier. Its purpose is to gauge the tone sound of the guitar. Number of custom levers can vary from 1 to 7 (very much affects the value of the instrument). Below is a picture with the "preamp EQ."

Recommendations for choosing 

Outset that beginners buy electroacoustics contraindicated! Instead of quiet systematic study of game technology for the beginner guitar must first be busy setting up the instrument and its frequency amplifier. And the price of such a system of tools is 20-30% higher than that of a normal guitar. The main purpose of electro-acoustic guitar - concerts and recording. This is very important, because to record the normal "mechanical" tool is much more complicated. Concert with it too difficult to give. Because of this and should start when choosing an instrument. And yes, it is worth remembering that when buying electroacoustic guitar percent 20% of the budget will have to spend on its "horn" - combo amp.

First level 

The market presents a variety of electro-acoustic guitar, the prices of which start somewhere around $ 150. It is better to pay $ 20 more and get a complete tool for the novice. He can and will come forward and register. Equalizer on this guitar will have only two regulator - the volume and the overall tone. 

Average level 

The musicians of the mid-level, of course, will not be enough. Electro-acoustic guitar Yamaha (even the cheapest) as a whole would meet their needs. Also pay attention to brands such as Cort and Fender. Prices for such instruments start at $ 350. On this guitar can be much thinner adjust timbre, and reliability they are much higher than cheaper counterparts. 

Advanced level 

For guitarists who catch tiniest deviations from the norms of sound, or for those who choose a guitar-companion for life, there is a premium brand of the Crafter, electro-acoustic guitar which otshumeli at thousands of concerts. They play psychedelic and Status Quo, and dark and mad grotesque Alice Cooper. In addition the firm Crafter has also Takamine, and Taylor. We do not insist on the fact that the choice is worth something because of these brands. Just before buying, carefully check the credibility of the brand, because the electric acoustic guitar, reviews of which is infinitely angry, hardly will live long. Do not forget that comments of ordinary people is more valuable than any advertising. Prices of premium guitars start somewhere on eight hundred dollars and tend to infinity. But the optimum range - is at 800-1400. E.
