• You can adjust bass/treble enhancement level only for front left/right 

channel. However, the supplied speakers cannot add the effective 
change to the bass sound because of their cutoff frequency even if the 
bass sound adjustment is made. (

output level of the subwoofer. (

When you play a disc (or software) encoded with Dolby Digital or 
DTS Digital Surround, the following symptoms may occur;
• Sound does not come out at the beginning of playback.
• Noise comes out while searching for or skipping chapters or 

tracks.

In these cases, change the decode mode to “DOLBY D” (for Dolby 
Digital) or “DTS” (for DTS Digital Surround).

The current decode mode appears on the display window.

Example: When “AUTO/PCM” is selected.

Each time you press the button, the decode mode changes as 
follows;

beginning)

• AUTO/PCM: Normally select this. The system automatically 

detects the incoming signals.

• DOLBY D:

Select this if the symptoms above occur when 
playing a disc (or software) encoded with Dolby 
Digital.

• DTS:

Select this if the symptoms above occur when 
playing a disc (or software) encoded with DTS 
Digital Surround.

• When “DOLBY D” or “DTS” is selected, if a signal encoded with 

another digital format comes in, you cannot listen to the sound. (The 
GDIGITAL or C indicator flashes.)

• Changing the source returns the decode mode to “AUTO/PCM” 

automatically.
