The ESC333 offers two unique
user-convenience features:
Automatic Turn-On/Shut-Down
and Automatic Digital-Input
Selection. 

The Automatic Turn-On feature
will turn the ESC333 on as soon
as a source connected to its
digital inputs (such as DVD, CD
player with digital output, or
any other device featuring a
coaxial or optical digital output)
is switched on, or as soon as the
unit connected to its last-used
analog input starts outputting
sound.

When using digital inputs, the
Automatic Turn-On can be
activated by turning on either
one of the connected digital
sources such as a DVD player or
a CD player with digital output.
When using analog inputs (TV or
AUX), Automatic Turn-On is
available only for the device
that was last listened to before
the ESC333 shut down. In order
to listen to the other device, the
ESC333 input needs to be
manually selected by using the
Input button on the product and
on the remote, which, in turn,
disables the Automatic Digital-
Input Selector until the ESC333
is shut down.

The Automatic Turn-Off shuts
the unit down five minutes after
all sources connected to its
digital inputs are powered down
and the device connected to its
selected analog input stops
playing.

The Automatic Digital-Input
Selector automatically selects
the source connected to its
digital inputs when that source
is powered on. Upon power
down of this digital unit, if no
other source is on, the ESC333
will switch itself off after five
minutes. 
If the analog source that was
selected prior to the digital
source turning on is still
playing, the ESC333 will switch
back to that other source.  Once
a digital source is powered on
and selected as an input,
turning on a device connected
to the other digital input will
not switch the input until the
selected digital device is first
powered off. 
These two features can only be
used if the customer does not
manually turn the ESC333 on or
off, and does not manually
select an input source. Once
either of these selections is
made manually, the automatic
features are disabled as follows:

1. If the ESC333 is turned off
manually, it will not turn back
on automatically until five
minutes after the source
connected to the ESC333 is shut
down. During these five
minutes, it can be turned on
either from the front panel or
via the remote control.
2. Once an input source is
selected manually, the
Automatic Source-Selection
feature will remain disabled
until the ESC333 shuts down.
3. Once any one of the two
devices connected to the ESC333
digital inputs is powered on and
its input is selected by the
ESC333, the device connected to
the other digital input of the
ESC333 cannot be automatically
selected until the already-
selected digital device is
powered down.
