The Atlona Gain™ 120 (AT-GAIN-120) is a compact power amplier designed for low or high impedance
applications. A mode selector switch allows it to deliver two channels of 60 watts each into 4 or 8 ohms, or a single
channel of 120 watts at 70 or 100 volts. This Class-D amplier is energy ecient, ENERGY STAR® qualied, and is
also convection-cooled to allow installation in conference rooms and quiet installation environments without the need
for fans. In addition to the amplied speaker output, a line level audio output allows the incoming audio to be fed
into an additional amplier or audio system. The Gain 120 is controllable via TCP/IP or external trigger, and can be
integrated with Atlona AV switchers and HDBaseT™ receivers for a wide variety of sound reinforcement applications.

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 amplier.
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.
