9. OPERATION
To operate the unit in the matrix mode, make necessary settings in advance such as the audio input/output
settings and event settings (including broadcast pattern and BGM broadcast group) according to the set
operation method.
9.1. Normal Use
In the matrix mode, the unit need not be manually operated in normal conditions since the set broadcast
patterns can be activated by means of remote control. However, it is also possible to adjust the volume,
activate the broadcast patterns directly, or turn on or off input/output channels using the front panel-mounted
keys and knobs.
This section describes operations that can be performed in normal use when the key lock function is disabled
and the unit is set to the matrix mode.

9.1.2. Power ON/OFF
Power is turned on when the power switch is pressed.
To turn off the power, hold down the power switch for 0.5 second or more.
Note
The power switch is a soft-switch, so the internal microcomputer is still operating even when the power switch
is set to OFF.
For Trigger, select "None" or "Control Input" (1 – 12). In Base settings, VOX cannot be selected for Trigger
nor can control outputs be synchronized with control inputs. Base settings are not required when only one
BGM program has been set in Route.
• BGM END
Defines the method of stopping BGM broadcasts. Only "Control Input" (1 – 12) can be selected for Trigger.
All current BGM broadcasts are stopped. Control outputs cannot be synchronized with control inputs.
To stop the specified BGM Event set in Route (including the case that the only one Base pattern is
broadcast) when two or more BGM Events are activated, turn off the corresponding input channel at the
unit's front panel.
