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 indica-
tors (28) LF (Left Front), 
C (Center), RF (Right Front),
LS (Left Surround), RS (Right
Surround) and SUB (sub-
woofer) will illuminate to indi-
cate 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) will not dis-
play unless Adjustment +/–
buttons are pressed. And,
while the status-bar indicator
(27) is on, channel indicators
(28) and LVL (29) will not be
displayed. Also, if adjustments
are done in a mode where a
certain channel is not avail-
able, the adjustment step for
that channel is skipped. For
example, in Phantom mode the
center-channel level cannot be
adjusted since Phantom does
not have a center channel. In
stereo, neither the center nor
the surround levels can be
adjusted since Stereo does not
feature surround speakers or a
center speaker. A seventh
press of the Level button will
exit the ESC333 from its level-
adjustment mode.

11. Adjustment
These buttons are used in con-
junction with Test (8), Delay
(9), and Level (10) to increase
or decrease a setting.

12. Bass
Press (+) to increase the level
of low-frequency information.
Press (–) to decrease the level
of low-frequency information.

13. Treble
Press (+) to increase the level
of high-frequency information.
Press (–) to decrease the level
of high-frequency information.

14–17. Input
One of these four indicators
will illuminate, depending on
which input is selected.

18–21. Surround
One of these will illuminate,
depending on which surround
mode is chosen.

22. Dolby Digital
Indicates the presence of a
Dolby Digital-encoded AC-3
digital signal.

23. 5.1-Ch

Dolby Digital indicator (22).
This indicator illuminates
when the Dolby Digital signal
contains 6 discrete channels of
information (one subwoofer
and five satellite channels).

24. Dolby Pro Logic
Illuminates when Dolby Pro
Logic decoding of a 2-channel
signal is taking place. This
indicator may be on by itself
(when analog inputs are
used), in conjunction with
Dolby Digital (when using a
digital input where the AC-3
format signal contains two
channels and needs to be
decoded into multichannel) 
or together with PCM (when
using a digital input where 
2-channel PCM-format data 
is being decoded into multi-
channel).

25. PCM
Illuminates when the signal
supplied through the selected
digital input is in PCM format.

26. Late Night
Illuminates when the Late
Night compression is selected.

27. Status-Bar Indicator
These LEDS show the relative
setting of volume, bass, 
treble, speaker level and

is in speaker-level adjustment
mode.

outlet and the master switch
on the back panel is in
On/Standby position, but
