1. Power
This button, located only on the
remote control, allows the user
to manually turn on or off the
ESC340. Please note that the
ESC340 features Automatic Turn-
On/Off, and the power switch is
not normally used unless it is
necessary to override this
automatic feature, or in case the
analog input to be used is not
the last one that was used and
so Automatic Turn-On is not
available for that input. Please
read the details regarding

Automatic Turn-On/Off on page
3 of this manual, and keep in
mind that the ESC340 automatic
turn-on feature will be disabled
for five minutes if the ESC340 is
shut down manually. The ESC340
can also be powered on by using
the Input button (4) on the
front panel of the subwoofer or
on the remote control. Please
note that if input selection is
done by pressing the Input
button, the Automatic Digital
Input Selection of the ESC340
will be disabled until the ESC340
shuts down. 

When the ESC340 is plugged into
a working electrical outlet and
its master switch on the back
panel is set to On/Standby, the
Standby (32) indicator will
illuminate. The ON (31) indicator
will light as soon as the ESC340
is turned on either automatically
or via the pressing of the Power
or Input buttons.

2. Mute
From either the front panel or
the remote control, press (Mute)
to lower the volume completely.
The mute symbol indicator (33)
will illuminate. When you press
either of the mute buttons
again, the volume will return to
its previous setting.
Note: The mute function can
also be turned off by pressing
either of the volume buttons on
the front panel or the remote
control.

3. Late Night 
This feature is available for
Dolby Digital only. It compresses
the inherently dynamic digital
sound so that the quiet and loud
passages are not quite as
different in sound levels as they
ordinarily are. This feature
allows the user to watch movies
and listen to dialogue at toned-
down levels so as not to disturb
others by the loud sound effects
that may be present. The Late
Night indicator (26) illuminates
when this feature is active.
