Input/Output Connectors
Standard XLR input and output connectors are provided on the rear panel. Pin 2 is wired
positive (hot) on the MIC INPUTS. Pin 2 is positive on the LINE OUTPUT when the front panel
Polarity switch (Rev ΓΈ) is in the normal out position. Pin 3 is positive on the LINE OUTPUT
when the front panel Polarity switch is pushed in (selecting the reverse phase condition).
DC Power Input
Connect the 2108 to the DC-30 Power Supply box using the supplied 2108 DC Power
Cable. Be sure the DC-30 Power Supply is turned off before connecting the 2108 DC Power
Cable to the 2108. Important! Never plug any other device into the 2108 DC Power
receptacle on the rear chassis of the 2108!
DC-30 Power Supply
The 2108 ships with an external power supply which provides DC voltages to the 2108 via
a supplied 7 pin XLR cable. Always use the supplied DC Power Cable. Using a similar
looking cable may damage the 2108 and the DC-30 Power Supply. The DC-30 has an
illuminated AC power switch. When this switch is on, the power supply will provide the
2108 with DC power. Both the 2108 power switch and the DC-30 power switch must be on
for the 2108 to work.
