Avoid stopping, pausing, switching the disc, cueing, fast-
forwarding or switching the audio channel of this unit while
making this adjustment. The setting is canceled if the Decode mode
is switched.
This adjustment is ineffective when the speaker is set to CENTER
OFF in Setting the Speaker (page 45).
This function only works with two-channel signals. This operation
is ineffective when 5.1-channel DTS or Dolby Digital signals are
input.
If the setting of REAR FILL is made when REAR MIX is ON, sound
is unchanged in the rear fill setting because REAR MIX is given
priority during 2 channel decoder other than linear PCM.
For linear PCM signals, the voice is output from the rear speaker
regardless of the REAR FILL and REAR MIX setting.
Linear PCM Setting
The output when playing discs recorded in linear PCM can
be set to 2 or 3 channels.
