Description
The Atlona AT-GAIN-M240 is a mixer amplifier designed for low or high impedance education and commercial applications. A mode selector switch allows the GAIN-M240 to deliver two channels of 120 watts each into 4 or 8 ohms, or a single channel of 240 watts at 70 or 100 volts.
Advanced Configuration Features
The GAIN-M240 is a highly flexible audio amplification platform that can be tailored to the specific requirements of virtually any application.
- Configurable inputs – Four analog inputs configurable for mono or stereo, mic (with phantom power support), or line level
- Signal processing – Gain and ducking per input, plus delay, high/low pass filters, equalization, and attenuation per output
- Multiple output mixes – Discrete mixes and independent gain control for amplifier and line outputs
- Ducking – Automatically lowers program audio when a priority signal (such as a teacher microphone) is detected
- Standby mode – Reduces power consumption and energy costs when idle
- Mute – Audio can be muted via contact closure, IP, or RS-232
Control
The amplifier supports IP, contact closure, and RS-232 control for integration with Atlona Velocity™ or third-party automation systems. Remote volume control is also supported via the optional AT-GAIN-VOL wall plate.
Mounting
The GAIN-M240 is housed in a rack-mountable 1RU, half-rack-width enclosure and ships with a short rack ear, long rack ear, and a dual mounting plate for installing two units side-by-side in a single 1RU rack space.
Networked Audio Interfaces
The optional AT-GAIN-NET audio bridge card supports two channels of Dante®, AES67, or Atlona OmniStream™ encoder audio over a network interface. The amplifier can also route audio to and from Dante® devices via API commands without the need for a Dante controller.
Applications
- Classrooms – Distribute lesson audio to low-impedance speakers, reduce program audio when a teacher microphone is active, and mute audio for PA announcements
- Meeting Rooms – Receive audio from an AV switcher or DSP and feed a high-impedance distributed speaker network
