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/LFE, 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: "1" key [DSP mode])
