Connect

Make the necessary connections as called out in the following

diagrams. Connect power last.

CAUTIONS:

lKeep the device unplugged until all of the input and

speaker wiring is complete.

lCheck the speaker wires for shorts and frayed wiring

around the speaker output connector.

NOTES:

lEnsure that the unit is properly grounded by

connecting the chassis ground lug to an earth ground

(building steel).

lTo prevent overheating, do not operate this product

in an area that exceeds the environmental

temperature range listed in the table of specifications

on the product web page.

Input Wiring

The amplifier inputs can be wired for stereo or mono audio

using balanced and unbalanced connections.

The audio inputs are summed as follows in Hi-Z (70 V or

100 V) and LoZ (4 ohm or 8 ohm) operation:

lLeft channel summing

oLeft input channel of terminal block (AUDIO IN +L-)

oLeft RCA input channel (AUDIO IN L)

oLeft channel of 3.5 mm audio input (AUDIO IN)

lRight channel summing

oRight input channel of terminal block (AUDIO IN +R-)

oRight RCA input channel (AUDIO IN R)

oRight channel of 3.5 mm audio input (AUDIO IN)

Balanced and Unbalanced Audio

The amplifier can receive balanced audio through the terminal

block connector and unbalanced audio through the terminal

block connector, RCA connectors, or the 3.5 mm connector.

Refer to the following diagrams when wiring the terminal

block connectors.

LoZ Operation

When the amplifier is set to LoZ operation (4 ohm or 8 ohm),

the MONO/STEREOswitch affects the input signals as fol-

lows:

lWhen set to STEREO, the amplifier will maintain separation

of the left and right audio input channels for stereo output.

lWhen set to MONO, the amplifier will sum the left and right

audio input channels for mono output.

Hi-ZOperation

When the amplifier is set to Hi-Z operation (70 V or 100 V),

the MONO/STEREOswitch affects the input

signals as follows:

lWhen set to STEREO, the amplifier will only use the left

audio input for mono output.

lWhen set to MONO, the amplifier will sum the left and right

audio input channels for mono output.

Speaker Connection

The amplifier can be configured for low impedance (4/8 Ω) or

high impedance (70 V or 100 V) operation. Refer to the

following diagrams:

Low Impedance (4/8 Ω, Mono or Stereo)

High Impedance (100 V, Mono Only)

High Impedance (70 V, Mono Only)

ALSOUT

The ALS OUT port provides a fixed audio output that pre-

serves left and right channel separation for use with assisted

listening devices. It is not affected by adjustments to volume,

bass, or treble.

Remote Control

The amplifier can be remotely placed in standby mode by a dry

contact closure connected to the REMOTE port.

Configure

Hi-Z/LoZ Switch

The amplifier can be configured to work with 4/8 Ω low

impedance (LoZ) loads or a distributed audio high impedance

(Hi-Z) 70/100 V system.

lLoZ: Set the switch to LoZ to use the amplifier with

4/8 Ω low impedance loudspeakers.

lHi-Z: Set the switch to Hi-Z to use the amplifier in a

70 V / 100 V distributed audio system. The Hi-Z LEDon the

front panel will illuminate.

MONO/STEREO Switch

The MONO/STEREOswitch operates as described below for

LoZand Hi-Z operation:

lLoZ Operation

oSTEREO: Set the switch to STEREO to maintain

separation of the left and right audio input channels for

stereo output.

oMONO: Set the switch to MONO to sum the left and

right channels for mono output.

lHi-Z Operation

oSTEREO: Set the switch to STEREO to only use the left

input channel for mono output.

oMONO: Set the switch to MONO to sum the left and

right channels for mono output.

Operate

Once the amplifier has been wired and configured, it is ready

for operation.

Apply Power

Apply power to complete the installation.

LEDBehavior

The LEDs on the front panel provide the following

information:

lPWR: When white, the amplifier is operating normally.

When red, the amplifier is in standby mode.

lHi-Z: When white, the Hi-Z mode is enabled (70 V or

100 V).When off, the LoZ mode is enabled.

lFAULT: When red, a fault is present or output protection is

enabled.

lSIGNAL:When white, indicates the presence of an audio

signal. When red, the input signal is too high and should be

lowered.

Adjust the Output

Adjust the VOLUME,BASS, and TREBLE controls to the

desired levels.
