Muting the Sound

Press MUTING to mute the sound through all
speakers 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.
Listening at Low Volume (Loudness)
Human ears are not sensitive to bass at low volume. To compensate
for this, the loudness function automatically boosts the bass level as
you lower the volume.
On the front panel ONLY:
Press LOUDNESS (SOURCE NAME) briefly
to select the loudness function.
• Each time you press the button, the loudness
function turns on (“LOUDNESS ON”) and off
(“LOUDNESS OFF”).
– Select “LOUDNESS ON” to activate the loudness function.
The LOUDNESS indicator lights up on the display.
– Select “LOUDNESS OFF” to cancel it.
The indicator goes off.
Note:
The loudness function affects the front speaker sounds 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 ATT indicator 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 function is available only for the sources connected using the
analog terminals.
• This function takes effect when the DSP mode is in use.
Adjusting the Subwoofer Output Level
You can adjust the subwoofer output level if you have selected
“YES” for the “SUBWOOFER” (see page 12).
Once it has been adjusted, the receiver memorizes the adjustment.

canceled before you finish, start from step 1 again.

1. Press BALANCE/SURROUND
ADJUST repeatedly until
“SUBWFR LEVEL” appears on
the display.
