A 120 Watt Commercial Mixer Amplifier that provides the perfect solution for commercial and industrial applications requiring great sounding, distributed audio coupled with power conservation and reduced operating expense. Capable of delivering high-quality sound over both Low-Z (4/8 Ohm) and High-Z (70/100 V) loudspeaker configurations and offers extreme flexibility on every channel. The CMA1201 is easy to install and operate – even for non-technical personnel. Simply put, the CMA1201 is ideal-suited for bars and restaurants, retail destinations, hotels, corporate, education or other venues needing background music and/or a public address system.

Easy to Install

The CMA1201 comes equipped with rubber feet, enabling the amps to be placed on a desk, shelf or any clear surface without any additional installation requirements. However, optional rack mounting hardware is also supplied, allowing one or several models to be housed and protected inside an enclosure. This adds extensive flexibility as a single product can be housed in a half 19" rack or full rack enclosure as well as a pair of amplifiers can easily be mounted side-by-side in a single rack space. With the included brackets the unit can also be mounted to a wall or under a table/shelf.

Automatic Power On/Off

The CMA1201 has a flexible power scheme with seamless and automatic power on/off based on the input signal, which reduces consumption when a signal is not present. With virtually zero configuration required, an energy smart and hassle-free amplifier system can easily be set up for hands-off operation. If the CMA1201 is powered on but does not receive an input signal for 20 minutes, the system automatically enters sleep mode to reduce power consumption. As soon as the Auto Ramp circuit detects a signal, the system powers on and normal operation resumes. The amplifier can also be instantly forced into standby mode or awakened via the front panel power button.
