If the signal source contains DTS encoded signals,
theMSD4 switches to DTS mode. The front panel CHAN-
NEL STATUS LEDs L, C, R, LFE, LS and RS will turn on
in accordance to the channels that are present on the DTS
sound track.
If the signal source contains only a Dolby Pro Logic
sound track, the MSD4 switches to Pro Logic mode. The
front panel CHANNEL STATUS LEDs L, R, and S will
turn on.
Volume Control
The MSD4 VOLUME control is factory preset with the
volume display indicating 75. This is the recommended ini-
tial volume calibration when the MSD4 is used in a system
with a C39 or MX130. If you wish to change the audio vol-
ume level from signal sources connected to the MSD4 rela-
tive to other signal sources selected by the C39 or MX130,
press the VOLUME push-
button to activate the MSD4
volume control. Adjust the
control until the desired level
is reached. Press the VOL-
UME push-button again to
deactivate the volume con-
trol. This will prevent an ac-
cidental change of the cali-
brated level
NOTE: If the input selector is set to (CD 1, SAT, LV or DVD)
and no digital signal is present, the Volume push-button
LED will flash on/off to indicate the outputs are muted.
When the outputs are muted the volume control
calibrated level will not function as described above.
Front Speakers (Small-Large)
When the front left and right speakers cover the full fre-
quency range down to 20Hz, set the switch to LARGE.
When the front speakers cover the frequency range only
down to 80Hz, set the switch to SMALL. A built-in elec-
tronic crossover will remove frequencies of 80Hz and

Center Speaker (None-Small-Large)
When the center speaker covers the full frequency range
down to 20Hz, set the switch to LARGE.
When the Center speaker covers the frequency range
only down to 80Hz, set the switch to SMALL. A built-in
electronic crossover will remove frequencies of 80Hz and
lower from the Center speaker and redirect them to the
Subwoofer speaker.
When there is no center speaker in the system, set the
switch to NONE. The Center channel signal is sent to the
left and right front speakers. This mode of operation results
in the listeners perceiving a Phantom center speaker.
Surround Speakers (Small-Large)
When the surround speakers cover the full frequency range
down to 20Hz, set the switch to LARGE.
When the surround speakers cover the frequency range
only down to 80Hz, set the switch to SMALL. The built-in
electronic crossover will remove frequencies of 80Hz and
lower from the surround speakers and redirect them to the
subwoofer speaker.

Set the SUBWOOF switch to ON whenever a subwoofer is
used in the system. In this mode, the LFE (Low Frequency
Effects) are always sent to the subwoofer. The subwoofer
also receives from any channel(s), that have their
SPEAKER switches set to SMALL, low frequencies of
80Hz and lower.
