Yamaha MA2030A Lo-Z / Hi-Z Switchable Class-D Mixer Amplifier

The Yamaha MA2030A is a Lo-Z / Hi-Z switchable Class-D mixer amplifier designed for background music and microphone applications in commercial environments. It delivers 30W x 2 channels in low-impedance mode and 60W x 1 channel in high-impedance mode (70V/100V), making it ideal for retail stores, restaurants, offices, and public spaces. Its compact 1U rack-mount design combines power efficiency with simple, intuitive operation.

Flexible Inputs and Built-In DSP Processing

The MA2030A offers versatile connectivity with 2 microphone inputs and 3 selectable stereo inputs, allowing easy integration of music sources and paging microphones. Advanced DSP functions enhance both music playback and speech clarity, including Feedback Suppressor, Priority Ducker, and Leveler. Bass and treble stereo source EQ with an enhancer function enables fine tonal adjustment, while the built-in high-pass filter ensures clean, controlled sound.

Optimized Speaker Support and Expandable Systems

Supporting both low-impedance (3Ω / 4Ω / 8Ω) and high-impedance (70V / 100V) speaker systems without external transformers, the MA2030A offers exceptional installation flexibility. It includes speaker EQ optimized for Yamaha VXC and VXS series speakers, ensuring consistent and balanced output. Service zones can be expanded by adding a PA2030a power amplifier, making the system scalable as needs grow.

Efficient, Reliable, and Environmentally Friendly Design

Powered by a highly efficient Class-D amplifier, the MA2030A delivers reliable performance with low power consumption and silent fan-less cooling. Intelligent protection circuitry safeguards both the amplifier and connected speakers, ensuring long-term stability. Certified as an ENERGY STAR® and Yamaha Eco Product, the MA2030A also features auto standby to reduce power usage, making it a dependable and eco-conscious choice for everyday commercial audio applications.
