bers, and if decreased shows minus numbers. Calibra-
tion levels can be adjusted over a range of plus or mi-
nus 12dB.
6. When the test signal switches to succeeding channels,
repeat the level calibration process until the test signal
volume levels of all the channels are the same.
7. The calibration channel cycling mode can be repeated
as often as necessary until you are satisfied that the
volume levels of the test signal are the same from all
channels.
8. Exit the System Calibration mode by pressing the SYS
CAL push-button a second time.
NOTE: All System Level Calibrations are retained in
permanent memory and will change only if calibration
is performed again. The factory default setting for the
volume control is 75.

Calibration
1. Set the
rear panel
SYSTEM
CALI-
BRATE
switch to
MAN.
2. Adjust the
MSD4
volume
control until the display reads at least 70, an initial ref-
erence setting to ensure that the test signals will be ad-
equately loud to perform the level calibration.
3. Press the SYS CAL push-button once to start Manual
System Calibration. The first time the SYS CAL push-
button is pressed, the test signal will switch to the Left
Front channel and will stay in that channel until the
SYS CAL push-button is pressed again, followed by
the Center, Right Front, Right Surround, Left Surround
and
Subwoofer. The MSD4 DELAY/VOLUME display
will read 0 for each channel before any adjustments
are performed.
NOTE: The front panel CHANNEL STATUS LEDs will light to
indicate which channel is reproducing the test signal. A
more convenient method of manually switching the test
signal is to use the SP push-button on the optional
HR34/HR39/HR130 Remote Control which performs the
same functions as the SYS CAL push-button.
4. While seated in the listening area, note the volume
levels of the test signal from each of the channels. If
you determine that the test signal volume is louder or
softer in any of the channels, the levels should be
adjusted so you hear essentially the same test signal
volume from all of the channels. The left front channel
volume level can serve as a reference.
5. Exit the Manual System Calibration mode by pressing
the SYS CAL push-button after calibrating the
Subwoofer channel.
NOTE: All System Level Calibrations are retained in permanent
memory and will change only if calibration is
performed again. The following table may be used to
record your Delay Calibrations Settings.
