Our 12-channel amplifiers combine outstanding features with lots of clean, high-current power. Built like a tank to commercial-quality standards, they satisfy the demands of almost any multi-channel, multi-room audio need.

The most common configuration is to divide the 12 independent amplifier channels equally into 6 stereo zones. But they can also be configured to power up to 24 speakers in just a single zone or divided between a combination of up to 6 stereo or 12 mono zones.

With up to 120 watts into each stereo zone (max 4 speakers), model DMA-1240 provides plenty of power for whole-house audio. Model DMA-1240ADS offers the same power but adds an innovative, auto-switching second audio input for every amp channel. This allows a second source, such as a voice-assistant streamer or TV, to be dedicated to those speakers, yet switch back to whole-house audio when desired.
