Switchable Class-D Power Amplifier

Lo-Z/Hi-Z switchable Class-D amplifier (Lo-Z: 120W x2 @4, 100W x2ch @3/8,?Hi-Z: 120W x2ch or 200W x1ch, 70V/100V) equipped with 1 stereo/2 mono line inputs; can be combined with the MA2120 mixer amplifier.

Key Features

• Easy setup, and a user-friendly interface for effortless operation
• Supporting Lo-Z (120W x2ch @4 or 100W x2ch @3/8) and Hi-Z (120W x2ch or 200W x1ch, 70V/100V) speaker systems
• 1 stereo/2 mono line inputs
• 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
• Certified as Yamaha Eco Products
• Space-saving 1U rack size (*sufficient space must be provided above and below the unit for airflow and cooling.)
