CMC3

Monitor Controller

FULLY FEATURED MONITOR CONTROLLER FOR STUDIOS OF ALL SIZES.
PRECISE, COMPACT & AFFORDABLE.

The CMC3 Compact Monitor Controller consolidates the feature sets of Drawmer's
3 most po pular monitor contro llers: W hilst retaining the famed accurate, and
transparent audio quality of the MC2.1, it has the precision and control of the MC3.1
and the low profile, compact design of the CMC2. It is equally at home in a serious
home studio as in a professional recording facility.

Accurate & Transparent

W ith the same Drawmer pedig ree as the MC2.1, the CMC3 circuit is just as
transparent and accurate. It has been designed to remove the limitations that a
passive circuit brings, such as the ability to increase the volume for quiet passages
and improved mix checking, without adding the artifacts that lesser quality active
circuits introduce. You hear exactly what you've recorded!

Precision

The CMC3 supports 3 sets of stereo monitors, plus a dedicated mono speaker/
sub-woofer output, each can be switched individually and simultaneously and in
any order, especially useful for A/B comparisons. You can listen to multiple speakers
with the same sub-woofer, or turn the sub-woofer off altogether.

The volume control utilizes a parallelled custom quad pot for excellent channel
matching and smooth feel, as does the secondary preset volume control on the
front. This provides repeatable calibrated output level for the monitors, so that at
the flick of a switch the engineer can hear the mix at the same predetermined
volume, time after time, without having to meticulously adjust controls.

Multiple Connections

The CMC3 is very well connected with 4 stereo inputs in total: 1x SPDIF digital input
(24 bit/192kHz), using the same DAC chipset as our established MC3.1 monitor
controller, 2 stereo balanced jack inputs, plus a 3.5mm jack with variable level
control for your Smartphone/MP3 Player.

In addition, it has a 2 pro fessional quality headphone outputs with a separate
amplifier and level control, that provide the same audio quality and mix checking as
the CMC3 does through the speakers. Talkback is also included with internal or
external microphone, level control and audio routing to a dedicated mono output
jack & headphones.

Advanced Mix Checking

The comprehensive mix checking facilities of the CMC3 include dim, mono, phase
reverse, left and right cut as well as an easy access mute switch, allowing you to
check the quality of your recordings: tune into your mix to hear any unwanted artefacts,
test the effectiveness of the stereo mix, check for phase cancellation, listen to the
stereo difference. Features that many monitor controllers lack.
