Connecting Audio Outputs
The DesktopBox has a mono, balanced line
level 1/4” TRS output jack on the rear of the
unit. That output is paralleled by the Audio Dis-
tribution Bay on the rear of the unit, where an
audio distribution module can be factory-in-
stalled. The DesktopBox does not offer multiple
output levels when more than one output is
used.
3rd party modules
The DesktopBox features a storage shelf
where a wide range of 1/2U 3rd party modules
can be installed, including wireless mic re-
ceivers, assistive listening transmitters, and
more. For convenience, the Desktop Box in-
cludes a 12VDC power jack on the rear of the
unit to power these units.
Operation
The DesktopBox provides four separate audio level
controls, one for each channel. When setting levels
for an audio channel be sure to monitor the ‘Clip’
LED to ensure that the mixer inputs are not being
overdriven. Overdriving, or clipping, the inputs can
lead to damage of the speakers connected to the
system and should be avoided. The DesktopBox
has a on/off power switch on the rear of the unit.
Be sure all input level controls are turned fully
down (max. counter-clockwise) before turning the
unit on or off.
Ducking Switch
The unit includes a three way switch which controls the ducking feature. When the switch is set to the
‘Mic’ setting, any input from the wired microphone connection will override (or duck) any active input
on other channels. When the switch is to the ‘W. Mic’ setting, any input from Line Input 3 will override
any active input on other channels.
