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).
