Atlona AT-GAIN-120 Stereo/Mono Power Amplifier, 120-Watts

Atlona AT-GAIN-120 Stereo/Mono Power Amplifier, 120-Watts

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.

NOTE: The AT-RACK-1RU rack shelf is a required accessory to ensure a proper, secure rack installation. Additionally, 2U of space will be required to install the Gain 120 in a rack.

Key Features

• Selectable low or high impedance operation
• 2 x 60 watts @ 4 or 8 ohms
• 1 x 120 watts @ 70 or 100 volts
• Class D efficient amplifier design
• Convection cooled - no need for fans
• Automatic standby, configurable from 5 to 25 minutes of inactivity, to minimize power consumption
• Rear panel input level controls
• Integrated protection circuitry automatically activates in the event of clipping, short circuit, thermal overload, and more
• Low inrush current to prevent audible “thumps” when multiple amps are powered on simultaneously
• Balanced line level output for pass-through to an additional amplifier or audio system
• Integrated five-band equalizer
