Installation
Verify operating voltage before applying AC mains. Replace fuse as needed for correct
voltage setting.
Install in a location that will give the MPA-2 proper ventilation on the top and sides.
Try to avoid mounting the MPA-2 near any other equipment that may emit large
magnetic fields like power amplifiers. The unit may pick up stray fields and pick up hum.
Plug in input XLR connectors and make sure they are all the way in.
Plug in output XLR connectors and make sure they are all the way in.
The two output connectors are paralleled and can drive two pieces of equipment.
Careful not to load down the MPA-2 with too low of an output impedance.
Dual outputs and be used for sending one output to monitor rack and the other to Pro
Tools rig if needed. Dual outputs have application for live sound support as well. If only
one output is needed leave the other XLR unused.
Pay close attention to the rear panel “Phantom Power Enabled” LED. Make sure what
you are plugging in to the XLR input requires phantom power. This voltage can cause
catastrophic damage to some ribbon type microphones. This LED is illuminated only
when the +48V function has been enabled from the front panel.
