REMOTE AND FRONT-PANEL CONTROLS AND INDICATORS
1. Power
This button, located only on the remote control, allows the
user to manually turn on or off the ESC333. Please note that
the ESC333 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 if the ESC333 is shut down using this
power button, its automatic turn-on feature will remain
disabled for five minutes after the source connected to the
ESC333 is also shut down. This is to prevent the ESC333
from repeatedly turning itself back on against the user’s
wishes. The ESC333 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 ESC333 will be disabled until the ESC333
shuts down.
When the ESC333 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 ESC333 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.
