Dsp Ram Through - Yamaha RX-Z9 Service Manual

2. DSP RAM THROUGH

• When using the digital PCM input, this is the signal path
through which the DIR output signals are inputted to all
the input ports of the decoder (SHARC) with the selector
(PLD) set to "DIAG MODE1". With other signal types, they
are reproduced using the ordinary process.
• Sp Config is always invalid.
• The operation of each SRAM is checked by the channel
output as listed below.

SRAM#1....... L/R, LFE (SWL/SWR)
SRAM#2....... L/R, SL
