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.
4. Input
This control is available on both the front panel and the
remote control. It allows manual selection when the user
repeatedly presses and releases the button for any of the
ESC333’s four inputs. The ESC333 features an Automatic
Digital Input Selection feature that automatically switches
the ESC333 to the source connected to one of its two digital
inputs as soon as that device is powered on. Please read
the section on page 3 to thoroughly familiarize yourself with
the conveniences and conditions of using the Automatic
Digital Input Selection feature. The Input switch is also used
when the source connected to the ESC333’s analog input is
not the analog source that was listened to the last time the
ESC333 was on (and hence the Automatic Turn-On feature
is not available). The Input switch also turns on the ESC333
when pressed (see item 1 earlier in this section). Whenever
a specific input is selected either manually or automatically,
its indicator (14, 15, 16 or 17) on the ESC333’s front panel
will be illuminated.
5. Surround Mode
Pressing and releasing this button allows the selection of
different listening modes. Surround (18), Phantom (19) and
3-Stereo (20) are available listening options for Dolby Digital
and Dolby Pro Logic. Stereo (21) bypasses the surround
processing and outputs sound through the right and
left-front speakers only. In Surround mode, all five satellites
and the sub-woofer will play. In Phantom mode, all speakers
except the center channel will play. In 3-Stereo, all speakers
except for the two surround speakers will be active.
6. Volume
Press (+) on the remote control or the front panel to raise
the system’s volume. Press (-) on the remote control or the
front panel to lower the system’s volume. The volume
setting is indicated on the status-bar indicator (27).
7. 0 dB
Press this button to reset the Center, Surround, Balance,
Treble and Bass controls to their default positions.
8. Test
Press this button to activate the Test Tone mode.
9. Delay
The relative timing of sounds coming from the center and/or
surround speakers compared to the front-left and front-right
speakers can be adjusted. The first press of this button
allows adjustment of the center channel, all the way from
the default setting of 0 ms (milliseconds), which means no
delay (all status bars off), to a maximum of 5 ms (5 status
bars on). The indicators C (28) and DLY (30) will be on. The
second press of the Delay button allows adjustments of the
surround speakers; indicators LS (28) and RS (28) and DLY
(30) will be on. The delay can be adjusted from zero (all
status bars off) to 15 ms (all status bars on) in 5.1 Channel
Dolby Digital and from 15 ms (all status bars off) to 30 ms
(all status bars on) in Dolby Pro Logic (there is an inherent
and fixed 15 ms of delay added in the “matrixed” Dolby Pro
Logic to recreate the proper surround effect). The center
and surround delay adjustments can be done from either
Dolby Digital or Dolby Pro Logic “matrixed” modes. There
are no separate delay adjustments for the individual modes
of operation. During adjustments, the audio mutes
momentarily every time the Adjustment +/– button (11) is
pressed. Please note that the status-bar indicator (27) will
not display unless Adjustment +/– buttons are pressed.
Also, while the status-bar indicator (27) is on, channel
indicators (28) and DLY (30) will not be displayed. And, if
adjustments are done in a mode where a certain channel is
not available, the adjustment step for that channel is
skipped. For example, in Phantom mode, the
center-channel delay cannot be adjusted since Phantom
does not have a center channel. In Stereo, neither the
center nor the surround delay can be adjusted since Stereo
does not feature surround speakers or a center speaker. A
third press of the Delay button will exit the ESC333 from its
delay-adjustment mode.
10. Level
The relative level of sounds coming from each of the
ESC333’s speakers can be adjusted while listening to
program material on the ESC333. Repeated pressing and
releasing of the Level button allows access to each channel.
The display will indicate LVL (29), and the channel
indicators (28) LF (Left Front), C (Center), RF (Right Front),
LS (Left Surround), RS (Right Surround) and SUB
(sub-woofer) will illuminate to indicate the active speaker.
The level for the selected channel can then be changed
using the Adjustment +/– buttons (11). Levels set in one
mode will stay valid for all other modes and are not
independent. Please note that the status-bar indicator (27)
