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 decrease the level
of high-frequency information.

14–17. Input
One of these four indicators will

22. Dolby Digital

Dolby Digital indicator (22).
This indicator illuminates when
the Dolby Digital signal

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.

compression is selected.

the back panel is in On/Standby
