TX Type A
• • • • Type A transmitter uses one ADC (Analog to Digital Converter) and transmits audio through Channel 2. Type 1 receiver (Rx)
uses one DAC and output audio through Channel 2. The firmware (that is downloaded to EEPROM IC) multiplexes which
channel to listen to (in this case Channel 2 since type A is transmitting from channel 2 In) by setting the baseband accordingly.
