DSP-A5
No.2 DSP THROUGH
The input is automatically discriminated by signal detection and switched with priorities Coaxial>Optical>Analog.
There are the following three sub-menus.
2 Y S S + S R AM M
1. YSS+SRAM
The L/R signals are output without being processed to the MAIN L/R through the AC3D2av.
The L/R signals are output without being processed to the CENTER/SUBWOOFER through the DSP.
The (L+R)/2 signals are output to the FRONT L/R and REAR L/R through the DSP and the SRAM.
When one of the L/R signals is not input, the output level is –6dB. (Remote control code 7A-89:"2" key [DSP mode])

3. DSP FULL BIT
Same as the above menu, except that the head margin is disabled, and the digital data is output with full bits from
AC3D2av to DAC.
