ART MPA Gold™ Microphone Preamplifier
When you plug into this jack it DISABLES the balanced input on the rear of the unit.
This feature allows you to keep the rear input patched in, and use the instrument input
to switch to a different source. The instrument input allows the MPA Gold to serve as a
great DI device as well.

Rear Panel Connections

Balanced Inputs

The MPA Gold's XLR connectors follow the AES standard of Pin 1 = Ground, Pin 2 =
Hot (+), Pin 3 = Cold (-). The Balanced inputs have an input impedance that is variable
from 150 to 3K Ohms via the front panel control. The Maximum input level is +19dBu
balanced and +17dBu unbalanced.

Balanced Outputs

The MPA Gold's flexible active balanced outputs are available on both ¼" and cannon
connectors. They offer low impedance for driving long cable runs and are intelligent
enough to maintain the same output level whether it is balanced or unbalanced.The
MPA Gold's XLR connectors follow the AES standard of Pin 1= Ground, Pin 2= Hot (+),
Pin 3= Cold (-). The balanced ¼" phone jacks are typical Tip = Hot (+), Ring = Cold (-),
Sleeve = Ground. Maximum output level is +26 balanced and +20 unbalanced.
