Key Features
• 2 x 60 watts @ 4 or 8 ohms
• 1 x 120 watts @ 70 or 100 volts
• ENERGY STAR® qualified
• Convection cooled – no need for fans
• Optional AES67 / Dante networked audio interface
• Available 1RU rack shelf – required accessory for rack installation
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 1RU rack shelf is a required accessory to ensure a proper, secure rack installation.
Networked Audio Interface (optional)
The Atlona AT-GAIN-NET is a networked audio interface card for the Gain 120 power amplifier. It features an AES67 and Dante dual-channel audio bridge, adding the capability to accept two channels over a network from a Dante or AES67-equipped DSP, as well as Atlona OmniStream AV encoders.
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.
