UHF Multi Channel Wireless Audio Transmitter and Receiver The WA-TX-03S and WA-RX-03S are 15 ch multichannel audio modules for analogue audio transmission. They operate in the European harmonized 863 to 865 MHz band with RF power selection of 5 and 10 mW. 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. 863 to 865 MHz European audio band Selectable RF output (5 mW and 10 mW) 15 RF channels with 125 kHz step Built in noise reduction systems Built in mute circuit Easy installation for user system CE / UKCA marking Audio guiding at museum Tour guide system Wireless conference system Wireless microphone system for amateur users Various audio transmissions Applicable standard Communication method Emission type Communication range Dynamic range 90 dB or more (W/IHF-A Filter) Audio frequency response Operating temperature Oscillation system Crystal based PLL oscillation Frequency stability Noise reduction type Spurious emission Audio input level Audio input impedance Max.
