Technomad DesktopBox Series Manuale utente
Technomad User Manual - DesktopBox
Thank you for purchasing a DesktopBox!
While intended for use with Technomad weatherproof
PowerChiton amplifiers and Scoreboard systems, the
DesktopBox can be used as an audio input interface
for any amplifier which uses balanced audio inputs.
The core of the DesktopBox is the audio mixer. The
mixer offers four separate audio inputs, each with level
control. The mixer includes a three-way ducking switch
option as well as internally accessible crossover points
and a simple limiter circuit.
The DesktopBox XL has an expansion bay where
factory-installed source options such as a wireless
microphone receiver, audio player and more can be mounted. Please contact Technomad to discuss
application requirements if the unit was not ordered with the needed optional module. On the rear of
the unit is an Audio Distribution Bay, where an audio distribution option such as a wireless, twisted
pair, or ethernet audio distribution transmitter can be mounted. The unit also includes an accessory
shelf where either an audio input or output accessory module can be mounted.
Installation
The DesktopBox series are designed to be deployed on a horizontal surface such as a desk or
counter. The unit is not weatherproof so should only be used in a dry location out of any precipitation.
The unit has a locking handle which also serves as a tilt leg. This can be used to carry the unit if
needed. To reposition the handle, simply press the buttons on side of the handle hub and rotate to the
desired position.
Connecting Audio Sources
To connect an external device to the unit, use an appropriate adaptor cable for the input. While the
DesktopBox is a mono device, an audio source with stereo output can be connected using the included
3.5mm to 1/4 adaptor on line input 1.

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.
