Delay and Level calibration procedures are made relative to
the listening area. The ideal listening area is defined as fac-
ing directly toward and centered between the front speak-
ers, and in line with the left and right surround speakers.
NOTE: Refer to the Front Panel Drawing on the opposite page
and Figures 1 & 2 on this page for the following steps.
Center Speaker Delay
If the center speaker is located closer to the listening area
than the left and right front speakers, its sound will reach
the listener before the sound from the left and right front
speakers. This difference in sound arrival times can degrade
the listening perception of some sound tracks. The MSD4
allows you to adjust the center speaker time delay to cor-
rect for this difference so the sound from the center speaker
reaches the listening area at the same time as sound from
the front left and right speakers.
NOTE: The MSD4 center delay can be adjusted from 0 to 5ms.
Each millisecond delay corresponds approximately to 1
foot in distance.
The first time you press the CNTR/DELAY push-button,
the DELAY/VOLUME display will indicate 0ms, which is
the factory default setting equivalent to no delay. This cor-
responds to a listening room where the center speaker is the
same distance from the listening area as the front left and
right speakers. If your center speaker is closer to the listen-
ing area than the front left and right speakers, adjust the de-
Figure 1
lay to correspond to the difference in feet.
1. Measure the distance from the listening area to the cen-
ter speaker and then the front left and right speakers. If
the center speaker is the same distance as the front
speakers, no calibration is necessary since the default
factory setting is 0ms. If the center speaker is closer
than the front speakers you should adjust the delay to
correspond to the difference in feet.

Press the CNTR/DELAY push-button to start delay
calibration procedure.
3. Adjust the VOLUME control until the DELAY/VOL-
UME display reads a number equivalent to how many
feet closer the center speaker is to the listening area.
4. Press the CNTR/DELAY push-button a second time to
exit the delay procedure.
Surround Speaker Delay
If the surround speakers are located closer to the listening
area than the front speakers, their sound will reach the lis-
tener before the sound from the front speakers. This differ-
ence in sound arrival times can degrade the listening per-
ception of some sound tracks. The MSD4 allows you to
adjust the surround speaker time delay to correct for this
difference so the sound from the surround speakers reaches
the listening area at the same time as sound from the front
left and right speakers.
NOTE: The MSD4 surround delay can be adjusted from 0 to
15ms. Each millisecond delay corresponds
approximately to 1 foot in distance.
