This year there are three models of wireless microphone system is significantly different from the traditional ones, and the difference is primarily in the amount of.
All television and radio microphones are many videoblogery-buttonhole Sennheizer, which are available for many years and are very expensive. Receiver and transmitter have a fairly high resolution and is powered by AA batteries. The wire is pulled from the microphone under the clothing and connected to the transmitter. The receiver is connected to the microphone input of the camera.
Of course, there is a Chinese alternative. On Aliexpress, you can find a variety of wireless microphone system, similar in appearance to the price of $ 25 (of course, for $ 25, the sound is poor and noise is inevitable). For example, CM-9 system with good reviews worth $ 105.
Recently there was a system of Sennheizer much smaller, but the principle is the same - a wire is pulled under clothing.
Much more interesting system RØDE Wireless GO, which costs $ 200.
The receiver and the transmitter is much smaller size (44x45x19 mm) than traditional Sennheizer. The transmitter has a microphone input and a built-in microphone, so you can traditionally secured transmitter belt stretching is carried out under the clothes, and use the transmitter to itself as Buttonhole-in microphone.
Elapsed time from a single charge of 8 hours.
Rode says that Wireless GO smallest wireless microphone system in the world, but this is not true. Startup PicoGear PicoMic released system, which transmitter is a microphone buttonhole sufficiently small size - 50x17x7 mm, weighs only 8 c.
The system is sold directly from the two microphones. They can be used for one person to record stereo sound and can be used for two people at the time of the interview. The receiver simultaneously a charging station for microphones.
Microphone in PicoMic located in the clip, so when worn on the lapel or pocket is visible only a small part of it. Despite its small size, wireless microphones PicoMic work on a single charge 10 hours.
Worth Picomic not cheap - $ 449, but it is cheaper than conventional Sennheizer on batteries and is much easier - not you need to pull the wire under the clothes and the process of donning the buttonhole on the interviewee takes several seconds.
Apparently, all new Wireless systems use digital audio broadcast.
Chinese still rivet numerous clones radiomikrofnnyh analog systems in large format old Sennheizer and something small and digital is not seen on Aliexpress.
For me remains a mystery why the creators of the radio microphones do not use Bluetooth technology. When using BT 5.0 APT-X no problems with sound quality and delays should not be.
