Volume Control
Adjust the VOLUME Control to select the desired level in
Zone A. The Volume Control adjusts all eight channels si-
multaneously, and level is indicated from 0 to 99 in the cen-
ter of the front panel display. To change the volume level in
Zone B when it is active, first press the Zone B Push-button
and adjust the front panel VOLUME Control to select the
desired level in Zone B. The Zone B volume level may also
be adjusted in the Zone B Room with a Remote Control or
Keypad.
System Off
Normally, Remote Zones are turned On and Off individually
in each respective zone by pressing the Power Push-button
on a Keypad or Remote Control. If you desire to switch Off
all zones of an entire McIntosh System simultaneously, in-
cluding a control center and accessory source components,
you can press the SYS OFF Push-button on the MX120
Front Panel. Refer to figure 34.
Note: The Sys Off Push-button on a Keypad or Remote
Control may also be used to switch Off the entire
system.
Setup
Pressing the SETUP Push-button for three seconds activates
the MX120 SETUP Mode for making changes to the Home
Theater System.
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 Track with encoded data that supports the compres-
sion function.
Reset of Microprocessors
In the event that the controls of the MX120 stop function-
ing, there is a built-in user reset function. Press the POWER
Switch to OFF and wait for two minutes. Then Press the
POWER Switch to ON. This will reset the MX120 micro-
processors. Refer to figure 33.
Note: The above condition is usually caused by either
interruptions in AC power and/or major changes in
voltage.
Front Panel Status
The front panel LEDs indicate the status of Operating/De-
coding Modes. Refer to figure 34.
