Doubted for buy this manual as it is my first order here and at not have cover image, I assumed would haven't. However, within 24 hs, already possessed the link to download it. The manual are scanned correctly and have all what is needed. Includes adjustments and diagrams of all circuits. Very satisfied.

Really good quality, аll readable.! Wonderful work shop. I recommend to all!
;
Good quality service manual.The scheme is on A3 format and very readable.Thank you
;
Very good service-manual with clear electrical diagrams. Thanks you.

the manual is in quite good quality and it's in pdf. manual was send in less then 6h.
Sync system A sync signal is generated on the TG-191/191P board. The signal input from the REF VIDEO IN or VIDEO IN connector is sync-separated to produce a sync signal (sync or burst). For SDI input locking, moreover, a sync signal is generated on the SDI-23 board by the signal input from the SDI IN connector. Based on the generated sync signal, a REF signal and various timing signals (CF, GOP, FRAME , HD, VD, and AUDIO ID signals) for the unit are generated on the TG-191/191P board . In addition, the video and audio clock signals synchronized with this sync signal are generated and sent to each board together with timing signals.
(2) Audio Signal Processing Block (CP-316, KY-400/406, AU-249, SDI-23, APR-27, and HP-88 Boards)
The analog audio signal input from the external equipment to the AUDIO IN connector (on the CP-316 board) is switched in an input level on the CP-316 board and controlled in a level on the KY-400 or KY406 board. The resultant signal is sent to the AU-249 board. On the CP-316 board, phantom power is also supplied. An automatic gain control (AGC) is applied to the audio signal sent to the AU-249 board. This audio signal and the Dolby noise-reduced analog Betacam PB audio signal are switched and emphasized. The resultant signal is converted from analog to digital and sent to the APR-27 board. For the SDI signal input from the external equipment to the SDI In connector, an audio signal and various control signals (mute flag, Z flag, and C bit signals) are extracted on the SDI-23 board and sent to the APR-27 board. On the APR-27 board, five-field sequence processing (for NTSC only) and JOG processing are performed for the SX PB audio signal sent from the DPR-87 board. This SX PB audio signal, the analog input signal sent from the AU-249 board, and the SDI input signal sent from the SDI-23 board are switched, swap in channels, mixed in channels, and muted. These signals are then sent to the boards below. REC signal: To the DPR-87 board LINE and MONITOR output signals: To the AU-249 board SDI output signal: To the SDI-23 board The LINE output signal sent to the AU-249 board is converted from digital to analog and de-emphasized. The signal is then output through the output amplifier on the CP-316 board from the connector panel. The MONITOR output signal sent to the AU-249 board is converted from digital to analog and deemphasized. The output signal is then gain-controlled on the HP-88 board and output through the output amplifier on the CP-316 board from the connector panel. The MONITOR output signal can also be monitored using headphones or speaker. The channel type of the signal to be output to the LINE and MONITOR output connectors can be set using a sub LCD menu. The output audio signal sent to the SDI-23 board is multiplexed with a video signal using an SDI encoder, converted from parallel to serial, and output from the connector panel.
