Power On
Press the POWER Switch to ON. The Red LED, to the
right of the POWER Switch, lights to indicate the MSE1 is
in Standby Mode. To turn ON the MSE1 press the
STANDBY/ON push-button. Refer to figure 7.
Note: The POWER Switch is only intended to be switched
OFF when the MSE1 Surround Expander is not used for
extended periods of time, like while away on vacation.
During normal operation, the POWER Switch should
stay in the ON position. Press the STANDBY/ON Push-
button for turning the MSE1 ON and OFF. When the
Power Control Cable is connected to a McIntosh A/V
Control Center or Surround Decoder, the MSE1
Surround Expander will automatically switch ON and
OFF.
Reset of Microprocessors
In the event that the controls of the MSE1 stop functioning,
there is a user reset function built in. While the MSE1 is
On, press and hold in the STANDBY/ON/RESET push-
button for five seconds, this will reset the MSE1’s micro-
processors. In rare circumstances the pushing of the
STANDBY/ON/RESET push-button for five seconds might
not reset the MSE1’s microprocessors. If that were to occur,
then place the POWER Switch to the OFF position for two
to five minutes and then back ON again.
Note: The above condition is usually caused by either
interruptions in AC power and/or major changes in
voltage.

Auto Mode
Pressing the AUTO MODE push-button places the MSE1
in the Automatic Surround Expansion Mode of operation
and the LED above the push-button lights. When the MSE1
receives, via it’s data port, the correct control signal the
MSE1 will automatically switch into the Surround Expan-
sion Mode and the Back Surround Loudspeaker(s) will re-
produce the added sound track information. If there is no
control signal present, the Surround Expansion Mode will
switch Off and no sound will be heard from the Back Sur-
round Loudspeaker(s). Refer to figure 8.
Note: Currently only the MX132 has the ability to pass on that
control signal to the MSE1. The MX132 continuously monitors
the digital signal bitstream from its rear panel optical or coaxial
digital inputs. The expander will only be engaged when specially
encoded 5.1 sound tracks are recognized by the MX132. If the
bitstream changes, the MSE1 processor is notified of the change,
which lights the EXPAND indicator and the appropriate
OUTPUT FORMAT LED’s.
Manual Mode
Pressing the MANUAL MODE push-button places the
MSE1 in the Surround Expansion Mode of operation and
the LED above the push-button lights. The MSE1 will con-
tinuously operate in the Surround Expansion Mode and
provide surround expansion from any 5.1 or Pro-Logic
sound track material that are reproduced with decorrelated
surround channels. The MSE1 lights the EXPAND indica-
tor and the appropriate OUTPUT FORMAT LED’s. Refer
to figure 8.
Sys Cal
A built-in test signal generator can be switched manually or
automatically through all surround channels for level cali-
bration. The levels can be adjusted ±6dB. The MSE1 has a
super precision volume trim control, and it’s tracking accu-
racy for all four channels is within one quarter of a dB
throughout its range. Refer to figure 6.
