Yamaha DSP-AX1/RX-V1 Service Manual page 17

Details of DIAG menu
In each menu, "SPEAKERS" is always set to "LARGE", D-RANGE to "MAX", LFE LEVEL to 0dB (-10dB when
DOLBY DIGITAL is used) and CENTER DELAY to 0ms unless otherwise specified.
1. DSP THROUGH
There are 3 sub menu items (ANALOG BYPS, DSP 0dB, FULL BIT).
1. DSP THROUGH

1. DSP THROUGH
DSP 0dB
ANALOG BYPS [Remote control code: 7A—90(PRG 9)]
• The input mode is fixed to use the analog (A/D) system.
• The L/R signal is output through the analog bypass without using the DSP section.
• C/RC, RL/RR, FL/FR, SWL/SWR signals are output using L/R through via DSP.
IC7
DSP6#1 YSS910
IC6
L/R
AC3D2av
YSS918
PCM THR
IC4
RLef : RL EFFECT
RRef : RR EFFECT
ZERO : Digital 0
AC3D2av outputs signals using 2ch though. (L/F)
• DSP6#1 outputs the L/R input signals to C/LFE (SD611), RLef/RRef (SD613), FL/FR (SD614),
RC (SD615, L only).
• DSP6#2 outputs the output signals from DSP6#1 to C/RC (SD621), RL/RR (SD623), FL/FR
(SD622), SWL/SWR (SD624).
Note: (SDxxx) represents a terminal name of DSP6#1 and DSP6#2.
