Input Connections

Installation Note

Keep input leads away from the output leads and AC power cables. Unless the driving source pro- vides a low-impedance output, keep the input lead under ten feet in length. Make all connections to the unit with the POWER switch in the OFF posi- tion.

source to the AUX 1 RCA jack (only works when the AUX 1/MIC 6 switch is in the AUX1 position).

AUX 2

The AUX 2 input uses an RCA plug and accepts input from a dedicated AUX source.

MIC 1 through 4 utilize female XLR-type microphone connectors. A slide switch located above each XLR connector is used to supply phantom power for con- denser microphones.

MIC 5/TEL

The MIC 5/TEL input is designed to accept input from a microphone or from a telephone line. A slide switch is provided to select MIC 5 or TEL input. To connect a microphone, place the MIC 5/TEL switch in the MIC position. Use two conductor shielded cable and con- nect the cable shield to the center GND terminal. To use the TEL input, place the MIC 5/TEL switch in the TEL position and connect the 600 ohm telephone pag- ing source (dry signal only - no DC voltage) to the MIC 5/TEL screw terminals.

MIC 6/AUX 1

The MIC 6/AUX 1 input is designed to accept input from a microphone using terminal strip connections or from a high level auxiliary source such as a tuner or CD player using the AUX 1 RCA jack. A slide switch is used to select input type. Connect a microphone to the screw terminals labeled MIC 6 (works only when AUX 1/MIC 6 switch is in the MIC 6 position). Use two con- ductor shielded cable and connect the cable shield to the center GND terminal. Connect an auxiliary input

Phantom Power for MIC 5 & MIC 6

A single internal jumper is provided to supply phantom power to both MIC 5 and MIC 6. The amplifier is shipped with the jumper in the OFF position. See the figure below for the location of the phantom power jumper.

Warning

Removal of the amplifier cover exposes internal components and presents an electrical shock haz- ard. For this reason, do not perform any functions requiring removal of the cover of the amplifier unless you are qualified to do so. Always discon- nect AC power from the unit before attempting to remove the cover.
