Stereo / Mono Power Amplifier – 120 Watts
The Atlona AT-GAIN-M120 is a mixer amplifier designed for low or high impedance education and commercial applications. A mode selector switch allows the GAIN-M120 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.
Advanced Configuration Features
The GAIN-M120 is highly flexible audio amplification platform that can be tailored to the specific requirements of any application:
- Configurable inputs – Four analog inputs may be configured for mono or stereo as well as mic (with support for Phantom power) or line levels.
- Signal processing – Supports gain and ducking adjustments for each input as well as delay, high/low pass filters, equalization, and attenuation for each output.
- Multiple output mixes – Discreet mixes and gain control are available for the amplifier and line outputs.
- Ducking – Lowers the level of program audio sources when a signal, such as a teacher microphone, is present on the selected input.
- Standby Mode – Reduces power consumption and energy costs when the amplifier is not in use.
- Mute – Audio from the amplifier can be muted via contact closure, IP, or RS-232.
Control
The amplifier includes IP, contact closure, and a RS-232 interfaces for control operations from Velocity™ or third-party control systems. It also supports remote volume control via the optional AT-GAIN-VOL wall plate for more simplified control.
Mounting
GAIN-M120 is housed in a rack-mountable 1RU, half rack width enclosure and ships with a short rack ear, long rack ear, and mounting plate for installing two of the amplifiers side-by-side in a single 1RU rack space.
Networked Audio Interfaces
AT-GAIN-NET is an optional audio bridge card that accepts two channels of Dante®, AES67, or Atlona OmniStream™ encoder audio over its network interface. Additionally, the amplifier has the ability to make routes to/from available Dante® Devices via API commands without the need for an Dante controller.
Applications
- Classrooms: Distribute lesson audio to low impedance speakers in the room, lower program audio when teacher speaks in a microphone, and mute audio for PA announcements.
- Meeting Rooms: The GAIN-M120 receive audio from an AV switcher or DSP, and then feed the audio to a high impedance distributed speaker network in the room.
Features
- Four analog inputs may be configured for mono or stereo as well as mic (with Phantom power support) or line levels.
- On-board mixer supports gain and ducking adjustments for each input as well as delay, high/low pass filters, equalization and attenuation for each output.
