Yamaha MA2120 Data Sheet
Overview
Lo-Z/Hi-Z switchable Class-D mixer amplifier that provide a smart and
simple solution.
Power Amplifier MA2120
Features
• Easy setup, and a user-friendly interface for effortless operation
• Supporting Lo-Z (120W x 2ch @4Ω or 100W x 2ch @3Ω/8Ω) and Hi-Z (120W x 2ch or 200W x 1ch, 70V/100V) speaker systems
• Flexible 6 mic/line inputs and 2 stereo inputs, with all 6 mic inputs featuring a 24V settings
• DSP functions for music playback and microphone use (Feedback Suppressor, Priority Ducker, Leveler, Compressor, Reverb & Echo)
• Bass and treble stereo source EQ with an enhancer function
• Output EQ for optimizing the sound of each Output channel
• Built-in speaker EQ optimum for Yamaha VXC/VXS series speakers, as well as HPF and selectable LPF settings
• Capable of controlling sources and volumes seperately in two areas (Source/volume zoning)
• Service areas or zoning areas can be expanded by adding a PA2120
• Remote volume control and microphone on/off switching via optional DCP control panels (DCP4V4S, DCP1V4S, DCP4S, max 2 units)
• Intelligent protection function ensures safe, reliable operation
• Certified by ENERGY STAR
• Space-saving 1U rack size (*sufficient space must be provided above and below the unit for airflow and cooling.)
