DSP sound modes

The digital sound processor (DSP) in the receiver can decode Dolby
Digital and DTS signals. It automatically determines the type of signal,
PCM, Dolby Digital or DTS, and processes it accordingly.
The DSP can add surround-like effects to stereo sources (analog or
PCM signals).
Choose from the STEREO, SURROUND, or SFC modes.
The DSP may interfere with radio reception. You can turn it off if this
occurs (á page 23).
Output is in stereo when you turn the DSP off so sound is only heard
through the front speakers.
Note
³PCM with a sampling frequency of 44.1 kHz is the digital signal for-
mat normally found on CDs. Some DVDs also use this format but
often with a higher sampling rate.
³The receiver cannot process other digital signal formats, such as
L R
MPEG and PCM signals with sampling frequencies of 96 kHz and
192 kHz.

FIXED
PCM
In rare cases, the receiver may have trouble recognizing the digital
signals on discs. With the PCM signals on CDs, this may cause the
beginning of a track to be cut off. Engage the PCM FIX mode if this
occurs.
FIXED
With DTS, the signals may not be recognized at all. Engage the DTS
FIX mode if this occurs.
This mode does not need to be changed under normal circumstances.
Change it only if the receiver appears to be having trouble recognizing
the software you are playing.
While the input source is selected and digital input is engaged:
Press and hold [DIGITAL INPUT].
The current mode is displayed. Press again to change the mode.
Each time you press the button:
AUTO>PCM FIX>DTS FIX
^--------------------------------------}
When a FIX mode is on, the receiver cannot process other signals.
This may cause noise to be output.
Select "AUTO" if this occurs.
The selected mode is stored even if the receiver is turned off.
