MONITOR CONTROLER

The MC3 is a compact passive monitor controller, designed to enable the studio engineer to
switch between two sets of monitors. This means that unlike some switchers that process the
recorded signal through active buffers, the MC3 is essentially a passive ‘straight wire’ device.
This means that it will not add noise, distort or color the main stereo signal. A custom-made
stereo potentiometer provides smooth control without introducing artifacts. A separate sub­woofer output lets you turn on or off the sub to compare mixes. All outputs may be calibrated
using the top-mounted recessed trim controls. Separate DIM switch and control lets you
reduce playback levels are return instantly without changing the master level control. A built
in headphone amp will power up to 4 sets of headphones including ear buds.

“It should be no big surprise
that Radial Engineering, those
devilishly clever Canadians with a
habit of inventing dozens of clever
little boxes that solve dozens of
studio problems, should eventually
address the question of easy­to-use, great-sounding monitor
control that anyone can afford to
install in even the smallest studio
arrangement.”
