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.
