IMPORTANT NOTE
Automatic On/Off and Automatic
Digital-Input Selection
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.
FEATURES
• Complete, self-powered Dolby* Digital home-cinema
sound system with five satellite speakers, subwoofer,
remote control, and all amplification built in. (Just Add TV!)
• Dolby Digital (AC-3* 5.1 channel), Dolby Pro Logic,*
including Phantom and 3-Stereo, and Stereo listening
modes.
• Automatic Turn-On and Turn-Off.
• Automatic Source Switching for the digital inputs.
• Two digital (one optical and one coaxial) inputs and two
analog inputs.
• 2-Way video-shielded micro-satellites with titanium
laminate tweeters and common voicing for all five channels,
and an 8-inch, long-throw, floor-firing subwoofer.
• Late Night compression for nighttime listening without
unexpected and objectionably loud passages.
• All amplification and controls are mounted in the
sub-woofer, eliminating the need for a separate control unit.
• Remote controllable via outboard remote eye that can be
mounted with the center channel or separately, so that the
subwoofer can be hidden away.
• Wall-mount brackets and floor stands available separately
for the satellites.
• Credit-card-type, full-function remote control.
• JBL “error free” speaker cables simplify connection and
eliminate possibility of out-of-phase wiring.
• Center foot for horizontal placement of the center channel.
• Rotatable JBL logos to allow for vertical or horizontal
placement of the satellites.
