We received the manual in a timely manner and it was exactly what we were expecting. Excellent replacement for original Service Manual.
All schematics are very legible. We are really satisfied.

(2) Audio Signal Processing System (CP-316, APR-42, SDI-23, AFM-16, AU262, HP-88)
Recording system The analog audio signals (CH1 and CH2) input to the AUDIO INPUT connectors (on the CP-316 board) is input by the CP-316 board and sent to the APR-42 board. In the CP-316 board, the Phantom power is supplied only for overseas models. The SDI signal input to the SDI INPUT connector is sent to the SDI-23 board, and serial/parallel converted. After the SDI audio signal is extracted by the audio Rx TBC block, the SDI audio signal is converted to serial, and sent to the APR-42 board. In the APR-42 board, the SDI input audio signal sent from the SDI-23 board is D/A converted, switched with the analog input signal sent from the CP-316 board, channel switched, channel mixed, and level controlled, etc. Then, the CH-1 and CH-2 audio signals are sent to the AU-262 board while the CH-3 and CH-4 audio signals are sent to the AFM-16 board. The audio signals (CH-1/CH-2) input to the AU-262 board are subject to DOLBY NR processing and waveform equalization after passing through the AGC/limiter circuit. They are then superimposed with the bias signal, and recorded on tape as the longitudinal audio signal. On the other hand the audio signals (CH-3/CH-4) input to the AFM-16 board are passed through the limiter circuit after NR processing, and then FM modulated. They are then sent to the RP-107 board as the AFM RF signal.
Playback system The longitudinal audio signals (CH-1/CH-2) play backed by the AT head are waveform equalized and DOLBY NR processed in the AU-262 board, and then level-controlled by the AFM-16 board. The C RF signals sent from the RP-107 board is subject to AGC in the AU-262 board, and after only the AFM audio signals (CH-3/CH-4) are demodulated, NR processing and level control are performed. The longitudinal audio signals and AFM audio signals which are level-controlled are sent to the APR-42 board. After the audio channel signals for line output and monitor output are selected, they are sent to the CP-316 board, and output from the connector panel via the 600 Z driver. The audio signal for monitor output can be monitored by the headphones or speaker inside the unit. The longitudinal audio signal and AFM audio signal sent to the APR-42 board are A/D converted, sent to the SDI-23 board, and multiplexed with the video data by the SDI encoder. They are then parallel/serial converted, and output from the SDI OUT connectors on the connector panel as the SDI signal.
