Muting the Main Room Sound

From the remote control ONLY:
Press MUTING to mute the sound through all
speakers in the main room and headphones
connected.
"MUTING" appears on the display and the volume turns off (the
volume level indicator goes off).
To restore the sound, press MUTING again so that "OFF" appears
on the display.
• Turning MASTER VOLUME on the front panel or pressing
VOLUME +/– on the remote control also restores the sound.

Reinforcing the Bass

Human ears are not sensitive to bass at low volume. To compensate
for this, the bass boost function automatically boost the bass level as
you lower the volume.
On the front panel ONLY:
Press BASS BOOST (SOURCE NAME)
briefly to select the bass boost function.
• Each time you press the button, the bass boost
function turns on ("BASSBOOST ON") and
off ("BASSBOOST OFF").
– Select "BASSBOOST ON" to activate the bass boost function.
The BASS BOOST indicator lights up on the display.
– Select "BASSBOOST OFF" to cancel it.
The indicator goes off.
Note:
This function affects the front speaker sounds in the main room only.

Attenuating the Input Signal

When the input level of the playing source is too high, the sounds
will be distorted. If this happens, you need to attenuate the input
signal level to prevent the sound distortion.
On the front panel ONLY:
Press and hold INPUT ATT. (SOUND
SELECT) so that the
INPUT ATT
lights up on the display.
• Each time you press and hold the button, the
Input Attenuator mode turns on ("INPUT ATT
ON") or off ("INPUT NORMAL").
Notes:
• This effect is applied to only the main room sources connected using
the analog terminals (except "DVD MULTI").
• This function takes effect when the DSP mode is in use.
