4. CONTENTS OF DIAGNOSIS FUNCTION
This section describes the contents of the self diagnosis function in detail.
No.1 ANALOG THROUGH
The input is fixed to analog (A/D). There are two submenus.
1. MAIN BYPASS
The MAIN L/R signals bypass the analog circuits to be output.
For CENTER/SUBWOOFER, FRONT L/R and REAR L/R, the MAIN L/R signals via the DSP are output without
being processed (through). (Remote control code 7A-88)
: This shows that the device is not operating.
2. DSP 0dB
MAIN L/R, CENTER/SUBWOOFER/LFE, FRONT L/R and REAR L/R pass through the DSP without being
processed.
: This shows that the device is not operating.
