jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam

7.1.3 SINGLE OPERATION METHOD Single operation method and input level.
A Note : Before the diagnosis, discharge the Amp power line. Connect the resistor of 100� or more between W301(VH+), W303(VH�) and GND (CN3003 Pin1) on the E-VOL ASSY. Refer to the next page about the points. The procedure and the input level of a single operation are shown below. 1. Short R84 with 1k� on the PRIMARY ASSY. 2. The power supply of the unit is turned on. 3. The terminal SPCONT (7 pin of CN3002) on the E-VOL ASSY is controlled by the following voltages. The initial state is �SP Relay is OFF� and �Sys. Mute is ON�. Apply DC+12V to SPCONT so that AMP can output to the speaker terminal. [ SPCONT ] CONT SP Relay Sys. Mute 0V OFF ON 5V ON ON 12V ON OFF

[ The Signal Input ] Note : This unit has the electric volume and this volume is only controled by U-com in the Receiver. So, please input the signal to the point after the electric volume output. Input Point R3101 R3102 Output Point Speaker Out Speaker Out Speaker Out Gain (1kHz) 36 dB 36 dB 36 dB Input Level(rms) Output Level(rms) 44.6 mV 2.8 V 44.6 mV 2.8 V This is matrix center, so only the phase differential part is outputted.
