Good qulity. Even as it is an old manual (from 1991-1992) it has a good scanned quality and is complete, including user's manual, disassembly intructions, diagrams and schematics, ajustments, troubleshooting and parts list, as usual with SONY manuals and Owner-manuals service.
The manual was of good quality with high resolution schematic diagrams.

� 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.
