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 amplier.
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.
