Installation
The AT-GAIN-120 provides two audio ports which provide analog audio input and output. The
ANALOG IN
port can
be used to connect an audio digital signal processor (DSP) or other audio source device. Balanced or unbalanced
wiring is supported.
The
LINE OUT
port can be used to connect an audio output device or daisy-chain to another amplifier.
The wiring for the
ANALOG IN
and
LINE OUT
ports, support either
balanced or unbalanced audio, as shown below. Both ports use the
included 5-pin captive screw connectors.
Connect program/stereo speakers to the included 4-pin captive screw
connector, then connect the terminal block to the
4 / 8 Ω OUT
port.
When connecting program / stereo speakers, set the
MODE
switch to
either 4 Ω or 8 Ω, depending upon the speakers impedance.
