Completely immerse yourself in the moment. With seven channels of massive power, the M27 can effortlessly create a truly
realistic surround sound experience that will transport you directly into a new hyper-reality. Rated at 180W continuous power
per channel, the M27 will provide over 300W dynamic power per channel with all channels driven. The M27 can accept both
balanced and single-ended inputs, and features high-quality binding posts for speaker connection. The compact dimensions of

with conventional IC driver circuitry. An added control loop
incorporating an integrator with adaptive clipping enables
20dB more feedback to be used across the audio band
because of its extremely low phase shift resulting in a dramatic
reduction in distortion across the audio band. This is added
to UcD’s already amazing characteristics of load invariance
and high current capability, common characteristics of great

exclusive SoftClipping™ feature is also included to protect
your speakers (and ears) from damaging clipping distortion.
Control for PowerDrive is derived by sensing the average
output power, applying a time constant, and then cleanly
hard clipping the signal thus limiting it to the rated continuous
clipping power over a sustained loading. By controlling the
power envelope maximum clean power is obtained for every
operating condition.
