Remote and Front-Panel Controls and Indicators
Front Panel
Remote Control
1. Power
This button, located only on the
remote control, allows the user to
manually turn on or off the Media
3000. Please note that the Media
3000 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 Media 3000 is shut
down using this power button, its
automatic turn on feature will
remain disabled for five minutes
after the source connected to the
Media 3000 is shut down also.
This is to prevent the Media 3000
from repeatedly turning itself
back on despite the user’s wishes.
The Media 3000 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
Media 3000 will be disabled until
the Media 3000 shuts down. 
When the Media 3000 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 Media
3000 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.
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
with the loud sound effects that
may be present. The Late Night
indicator (26) illuminates when
this feature is active.
-10-
4. Input
This control is available on both
the front panel and the remote
control. It allows manual selec-
tion when the user repeatedly
presses and releases the button
for any of the Media 3000’s four
inputs. The Media 3000 features
an Automatic Digital Input
Selection feature that
automatically switches the
Media 3000 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 Media
3000’s analog input is not the
analog source that was listened
to the last time the Media 3000
was on (and hence the
Automatic Turn-On feature is
not available). The Input switch
also turns on the Media 3000
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 Media 3000’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 out-
puts sound through the right-
and left-front speakers only. In
Surround mode, all five
satellites and the subwoofer 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 (see Test Tone
section).
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 (milli-
seconds), 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 re-create 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 Media 3000 from its
delay-adjustment mode.
10. Level
The relative level of sounds
coming from each of the Media
3000’s speakers can be adjusted
while listening to program
material on the Media 3000.
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
(subwoofer) will illuminate to
indicate the active speaker. The
level for the selected channel
can then be changed using the
Adjustment +/– buttons (11).
-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 display 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
available, 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 Media
3000 from its level-adjustment
mode.
11. Adjustment
These buttons are used in
conjunction 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
Works in conjunction with the
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
multichannel).
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 speaker delay.
28. Speaker Indicator
Identifies the speaker that’s
being adjusted. LS is Left
Surround, LF is Left Front, C is
Center, RF is Right Front, RS is
Right Surround, and SUB is
Subwoofer.
29. Level
Illuminates when the Media
3000 is in speaker-level
adjustment mode.
30. Delay
Illuminates when the Media
3000 is in speaker-delay
adjustment mode.
31. On
Indicates that the Media 3000 is
fully powered up.
32. Standby
Indicates that the Media 3000 is
plugged into an active wall
outlet and the master switch on
the back panel is in On/Standby
position, but the unit is not
powered on.
33. Mute
Illuminates when the mute
function is activated (the Media
3000 will be on but will not
produce any sound).
-12-
LED Bar Indicators illuminate in
response to adjustments in 
volume, delay, level, bass and
treble controls.
