The first time you press the SURR/DELAY push-button the
DELAY/VOLUME display will indicate 5, which is
equivalent to a 5 millisecond delay which is the factory de-
fault setting. This would correspond to a typical listening
room where the surround speakers are 5 feet closer to the
listening area than the front speakers. If your surround
speakers are in a different location, adjust the delay to cor-
respond to their distances from the listening area relative to
the front speakers.
1. Measure the distance from the listening area to the sur-
round speakers, and then to the front left and right
speakers. If the surround speakers are the same distance
as the front speakers, the calibration delay should be set
to 0ms. If the surround speakers are closer than the
front speakers you should adjust the delay to correspond
to the difference in feet.
2. Press the SURR/DELAY push-button to start delay cali-
bration procedure.
3. Adjust the VOLUME control until the DELAY/VOL-
UME display reads a number that is the same as the
number of feet measured in Step 1.
4. Press the SURR/DELAY push-button a second time to
exit the delay procedure.
EXAMPLE: If your center speaker is 2 feet closer to the
listening area than the front speakers, set the
center delay to 2. If your surround speakers are
4 feet closer to the listening area than the front
speakers, set the surround delay to 4.
NOTE: The following table may be used to record your Delay
Calibration Settings.
The following information assumes the MSD4 is being
used in a system together with a digital signal source such
as a McIntosh MLD7020 Laser Video Disc player, a DVD
player or a Satellite Receiver. The MSD4 is operated by an
HR34/HR39/HR130 Remote Control sending IR signals to
the Control Center sensor.

Selecting inputs with the Remote Control results in the
MSD4 input selection automatically tracking with the Con-
trol Center input. If Inputs are selected manually by turning
the C39 or MX130 LISTEN switch, the matching MSD4
inputs must also be selected manually by the MSD4 IN-
PUT switch.
The DVD input on the MSD4 is the same as the V-AUX
input on the Control Center. If any input other than the four
MSD4 inputs are selected, the MSD4 will default to the
Analog input.
NOTE: If your C39 or MX130 has the THX-M module installed,
switch the Control Center back to internal processing
CINEMA 2 to take advantage of the THX
enhancements to the Dolby Pro Logic decoded sound
tracks.
FP Sensor
Set the FP SENSOR switch to OFF.
NOTE: This prevents the MSD4s built-in sensor from receiving
the remote control commands that have been already
received directly from the C39 or MX130, thus causing
improper functioning. Refer to Figure 3.
Late Night
The LATE NIGHT push-button turns a volume compres-
sion circuit on and off. This feature suppresses loud sounds
or music that might disturb neighbors or others not in the
immediate area of the home theater. Soft levels are also
raised slightly so they are still listenable at reduced overall
volume levels. This works only on a Dolby Digital sound
tracks with encoded data that supports the compression
function.
Re-EQ + TM
Re-EQualization
TM
compensates for the bright sound re-
quired in theaters that is not needed in a home theater sys-
tem. TM or Timbre Matching
TM
makes the movement of
sounds around the listening room much more natural and
realistic by compensating for how the human ear hears
sounds from the sides compared to sounds heard from the
front.
Channel Status LEDs
If the signal source contains a Dolby Digital sound track,
the MSD4 switches to Dolby Digital mode. The front panel
CHANNEL STATUS LEDs L, C, R, LFE, LS and RS will
turn on in accordance to the channels that are present on
the Dolby Digital sound track.
