Introduction
CMA1201
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.
