Yamaha Amplifier Technology

Yamaha is a world leader in the field of professional audio equipment.

Yamaha mixing consoles and amplifiers are used in many of the world’s top recording studios and music venues, setting the standard for pure, natural sound.

This expertise and experience are behind the creation of the KMA-980, so they deliver powerful output with clear, rich sound that’s perfectly tuned to make voices sound their best.

Choice of 2 Great Echo Modes


Yamaha’s exclusive Echo Modes, the same as Karaoke Echo on the legendary REV100 Digital Reverberator.

The sound is full and dynamic, and the left-right delay time gives a wider stereo effect than ordinary echo. The KMA-980 offers a choice of Normal and Wide Echo.

With Echo Modes, every song and every singer sounds great!

High Power, High Quality


Using EEEngine technology, this amplifier delivers 150W of clean, reliable power.

Their high efficiency means it operates with low heat and low noise, and unlike ordinary analog amps do not require a low-pass filter that degrades audio quality.

Designed to maximize quality from microphone input, the sound has good response in all frequency ranges, low distortion, no coloration and plenty of power in the midrange for dynamic vocals.

Active Howling Canceller

Annoying howling sounds are a thing of the past, thanks to Yamaha’s Active Howling Canceller.

It automatically limits howling without affecting the vocals, so is convenient and improves sound quality.

Music Out Preout for Greater Clarity

Unlike the usual four-channel output that mixes the Vocal and Music signals in each channel, these amplifiers can output the Vocal signal and Music signal separately.

This allows a four-speaker system with different Vocal and Music channels, so you enjoy stereo Vocal with clearer sound quality.

Four-Gang Rotary Encoder Knobs

The large control knobs are four-gang rotary encoder types, ensuring smooth, responsive operation with a professional feel.

The volume knob has LED number indications, so it is easy to see in a room with low lighting.

Convenient Input Jacks

The KMA-980 has 2 front and 2 rear mic inputs, and 1 speaker terminal.

In addition, it has 3 audio and 2 video inputs.
