Introduction

The Atlona Gain 120 (AT-GAIN-120) is a compact power amplifier designed for low or high impedance applications. A mode selector switch allows the Gain 120 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 amplifier is energy efficient and ENERGY STAR qualified, and is also convection cooled to allow installation in conference rooms and quiet installation environments without the need for fans. In addition to the amplified speaker output, a line level audio output allows the incoming audio to be fed into an additional amplifier or audio system. The Gain 120 is controllable via TCP/IP or external trigger, and can be integrated with Atlona AV switchers and OmniStream AV systems for a wide variety of sound reinforcement applications.

Networked Audio Interface Available
Available for the Gain 120 is the AT-GAIN-NET networked audio card, featuring an AES67 and Dante dual-channel audio bridge. The AT-GAIN-NET adds the capability to accept two channels over a network from a Dante or AES67-equipped DSP, as well as Atlona OmniStream AV encoders.

Applications

Applications
Meeting rooms, conference rooms, training rooms, and classrooms - The Gain 120 can receive audio from an AV switcher or DSP, and then feed the audio to program speakers on the front wall, or a distribution of ceiling speakers.
Facility audio systems - The Gain 120 can be integrated with a centralized audio distribution system for paging and background music, as well as audio content targeted to specific zones.
