The MA2120 from Yamaha is a 2-channel, Class-D mixer amplifier designed to provide high-quality audio in music playback and microphone use. It’s equipped with six flexible mic/line inputs and two stereo inputs, with all mic inputs featuring a 24V setting. Its powerful DSP functions include Feedback Suppressor, Priority Ducker, Leveler, Compressor, and Reverb & Echo.
Experience easy setup and intuitive operation. Switch between Lo-Z (120W x2ch @4 or 100W x2ch @3/8) and Hi-Z (120W x2ch or 200W x1ch, 70V/100V) speaker systems. Optimize each channel using Output EQ. Other features include bass and treble stereo source EQ with an enhancer function, as well as Intelligent Protection to ensure safe, reliable operation.
Taking up a compact 1U rack size, the MA2120 requires sufficient space above and below the unit for adequate airflow and cooling. It also incorporates speaker EQ that’s optimized for Yamaha’s VXC/VXS series speakers, as well as HPF and selectable LPF settings. This mixer amplifier can be remote-controlled for volume and mic on/off switching by using up to two optional DCP control panels (external components sold separately).
The MA2120 is ENERGY STAR certified.
