Listening to your system

Choosing the listening mode

This receiver offers a variety of listening modes to 
accommodate playback of various audio formats. Choose 
one according to your speaker environment or the source.

 …

While listening to a source, press the listening mode 
button repeatedly to select a listening mode you want.

The listening mode is shown on the display on the front 
panel.

Important

The listening modes and many features described in this 
section may not be available depending on the current 
source, settings and status of the receiver.

Listening in surround sound 

Using this receiver, you can listen to any source in surround 
sound. However, the options available will depend on your 
speaker setup and the type of source you’re listening to.

If the source is Dolby Digital, DTS, or Dolby Surround 
encoded, the proper decoding format will automatically be 
selected and shows in the display.

The following modes provide basic surround sound for stereo 
and multichannel sources.

a.

You can also adjust the 

C.WIDTH

DIMEN.

, and 

PNRM.

 effect 

(see 

Setting the Audio options

 on page 26

).

b.

You can also adjust the 

C.IMG

 effect (see 

Setting the Audio 

options

 on page 26

).

Playing back in the STEREO mode 

When you select 

STEREO

, you will hear the source through

just the front left and right speakers (and possibly your
subwoofer depending on your speaker settings). Dolby 
Digital and DTS multichannel sources are downmixed to 
stereo.
When the headphones are connected, 

STEREO

 can only be 

selected.

Using the DSP 

The DSP feature creates a variety of surround effects. Try 
different modes with various soundtracks to see which you 
like.

Using Direct 

Use the Direct modes when you want to hear the truest 
possible reproduction of a source. All unnecessary signal 
processing is bypassed.

Using the Advanced Music Optimizer 

When audio data is removed during the compression 
process, sound quality often suffers from an uneven sound 
image. The  Advanced Music Optimizer feature employs new 
DSP technology that helps bring CD quality sound back to 
compressed 2-channel audio by restoring sound pressure 
and smoothing jagged artifacts left over after compression.

 …

Press 

M.OPT

 to switch the M.OPT (Advanced Music 

Optimizer) ON or OFF.

Note

The Advanced Music Optimizer mode cannot be set to 

ON

when the 

DIRECT

 mode is switched on.
