FULL BIT [Remote control code: 7A—92 (PRG11)]
• The head margin is unused and the digital data is output in full bit.
• The same applies as "DSP 0dB" except that the digital data is output in full bit at D/A but
SWFR is not output in full bit.
Condition
0dB [Remote control code: 7A—93 (PRG12)]
• The input signal is automatically identified and switched in the priority order of dts
DIGITAL PCM AUDIO
• L/R, C/RC, FL/FR, RL/RR and SWFR signals are output through DSP (see the signal
path in the figure below) without using the external DRAM.
(The SDOB output is inputted to DAC of MAIN L/R. Other than that, everything is the
same as DSP THROUGH.)

MAIN L/R: -18dBFS
CENTER: -6dBFS
REAR CENTER: -3dBFS
FL/FR: -6dBFS
RL/RR: -18dBFS
SWFR: Add L/R signal at -20dBFS.
