DRAWMER
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 popular monitor controllers: Whilst 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
With the same Drawmer pedigree 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 usefulforA/Bcomparisons.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 professional 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
checkthe qualityofyourrecordings:tune intoyourmix tohearanyunwantedartefacts,
test the effectiveness of the stereo mix, check for phase cancellation, listen to the
stereo difference. Features that many monitor controllers lack.

or give A/B comparisons.

bangs.

DRAWMER
INSTALLATION
The CMC3 is a free standing, desktop unit. We have endeavoured to make the
CMC3 as small as possible without compromising on controls, connections and
above all sound quality. The unit has a footprint of just 27cm x 16cm with controls
on the top, headphone and mp3/phone input on the front and all other connections
on the rear panel.

POWER CONNECTION
7
The CMC3 unit will be supplied with an external switching mode power supply that
is capable of 100-240Vac continuous (90-264Vac max) and so should work globally.
We strongly advise that the power supply that has been supplied with the CMC3 is
used, rather than one with the equivalent ratings. In addition, should the power
supply fail for any reason we strongly advise that you contact Drawmer for a
replacement rather than repairing the unit yourselves. Failure to do either of these
could permanently damage the CMC3 and will also invalidate the warranty.
The power supply will be supplied with 4 interchangeable AC pins for the UK,
European, USA and Australian socket types. For your own safety, it is important that
youuse thecorrect adapter.The powersupply mustnot betampered withor modified.
Before connecting the CMC3 to the power supply ensure that all knobs are
turned off (i.e. fully anticlockwise). A switch next to the d.c. power inlet on the rear
of the unit switches the power on/off.
To help protect the CMC3 from theft the side has a Kensington Security Slot (also
called a K-Slot) which enables the fitting of hardware locking accessories that can
attach your CMC3 to an immovable object, making the CMC3 more of a challenge for
the potential thieves to steal.

AUDIO CONNECTIONS
• Ground Loops:
If ground loop problems are
encountered, never disconnect the
mains earth, but instead, try
disconnecting the signal screen on
one end of each of the cables
connecting the outputs of the CMC3
to the patchbay. If such measures
are necessary, balanced operation
is recommended.
8
• Interference:
If the unit is to be used where it
maybe exposed to high levels of
disturbance such as found close to
a TV or radio transmitter, we advise
that the unit is operated in a
balanced configuration. The
screens of the signal cables should
be connected to the chassis
connection on the XLR connector as
opposed to connecting to pin1. The
CMC3 conforms to the EMC
standards.

CONTROL DESCRIPTION
As well as a transparent and precise signal path the CMC3 Compact Monitor
Controller incorporates many impressive features which are invaluable to the sound
engineer when listening to and examining the quality of the audio.
CHAPTER2
1SOURCESELECT
Four switches select which of the analogue inputs -I/P1, I/P2 (9) and AUX (1b), and
digital input -DIGI (8), are heard at the Speaker Outputs (10) and Headphones(6b).
Each can be operated individually or simultaneously and in any combination. When
operated simultaneously the individual signals are summed into a single stereo
signal. Note that the CMC3 does not provide individual level trims for the I/P1, I/P2
and DIGI inputs and so any level matching should be applied before it reaches the
CMC3.
The digital DAC converts up to 192kHz/24 Bit and is via SPDIF (8) phono socket
located on the rear. A LOCK led above the switch shows when the signal is strong
and the CMC3 is locked in, if not lit the digital signal should be checked.
An AUX 3.5mm stereo jack input is located on the front panel (1b) to allow easy
access to connect a MP3 player, smartphone or similar audio device. A control
knob (1c) allows the adjustment of the AUX volume to match the system level.
