UHF Multi Channel Wireless Audio Transmitter / Receiver
WA-TX-03-R, WA-RX-03-R
863 MHz
The WA-TX-03-R / WA-RX-03-R are 15ch multichannel audio modules that operate in the European harmonized 863 - 865 MHz band. In
addition to offering a frequency response range sufficient for voice transmission, the compander noise reduction
system has a wide dynamic range, enabling transmission of clear audio signals. As embedded devices, they include
nearly all the parts necessary for audio transmission in a small shielding case, making it possible to develop
audio transmission equipment in a short time.
