Stereo/Mono Audio Power Amplier - 120 Watts
AT-GAIN-120
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.
