Acurus Multi Channel Amplifiers
The M4 uses a patented Class D amplifier topology that is incredibly efficient, quiet, and free of any hint of audio distortion. While the M4 is ideally paired with the Acurus MUSE immersive processor for a supreme marriage of world-renowned Acurus audio engineering, this amplifier is flexible enough to pair up with virtually any high-quality preamplifier to deliver high power and outstanding audio specifications.
Perfectly sized for media and multipurpose rooms, the Acurus M4 is bristling with control options in its compact 2RU frame. Interface through IR, 12V trigger, RS232, ethernet, and use the M4’s beautiful mobile app for control, or through one of the many 3rd party control solutions supported by the M4.
Combine with the MUSE and an Acurus M8 for an exhilerating 7.1.4 immersive experience.
