Balanced Inputs
The DIGITAL MPA II’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 DIGITAL MPA II ‘s flexible active balanced outputs are available on both ¼” and cannon connec-
tors. They offer low impedance for driving long cable runs and are intelligent enough to maintain the
same output level weather it is balanced or unbalanced.
The DIGITAL MPA II’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.
