Introduction

The Atlona Gain 60 (AT-GAIN-60) is a compact power amplifier designed for low or high impedance applications. A mode selector switch allows the Gain 60 to deliver two channels of 30 watts each into 4 or 8 ohms, or a single channel of 60 watts at 24, 70, or 100 volts. This Class D amplifier is energy efficient and ENERGY STAR qualified, and is also convection cooled without the need for fans. Additionally, the Gain 60 is UL 2043 plenum rated, allowing convenient yet discreet installation in a plenum airspace above a drop ceiling. Balanced and unbalanced inputs are provided for system design versatility. The Gain 60 is controllable via TCP/IP or RS-232, and can be integrated with Atlona AV switchers and OmniStream AV systems for a wide variety of sound reinforcement applications.

Applications

• Meeting rooms, huddle rooms, and classrooms - The Gain 60 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.
• Plenum airspaces - The Gain 60 can easily be concealed above a drop ceiling, minimizing the need for AV equipment space in a room.
