CHAPTER 1 ONE YEAR LIMITED WARRANTY Drawmer Electronics Ltd., warrants the Drawmer CMC2 Compact Monitor Controller to conform substantially to the specifications of this manual for a period of one year from the original date of purchase when used in accordance with the specifications detailed in this manual.
DRAWMER CMC2 Compact Monitor Controller Building on their success in the stereo monitor controller market, Drawmer are aiming to complete their range with the CMC2, a low cost, low profile, compact desktop controller. Using the same audio circuitry as the ever popular MC2.1 & MC3.1 monitor controllers, Drawmer have reduced the feature set to produce a more cost effective solution, primarily aimed at the home studio market. The CMC2 has 2 Stereo Inputs on ¼” balanced jacks, plus a 3.
Can you trust the audio that your current monitor controller is providing? Is it colouring the sound? For all Drawmer monitor controllers it is imperative that what you record is exactly what you hear. The active circuit has been designed to faithfully produce the audio signal whilst removing many of the problems that a passive circuit will bring. There is one thing that should always be absolutely guaranteed that you can rely on the accuracy of your monitor controller.
DRAWMER INSTALLATION The CMC2 is a free standing, desktop unit. We have endeavoured to make the CMC2 as small as possible without compromising on controls, connections and above all sound quality. The unit has a footprint of just 18cm 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 The CMC2 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 CMC2 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.
DRAWMER AUDIO CONNECTIONS • 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 CMC2 conforms to the EMC standards.

CHAPTER 2 DRAWMER CONTROL DESCRIPTION As well as a transparent and precise signal path the CMC2 Compact Monitor Controller incorporates many impressive features which are invaluable to the sound engineer when listening to and examining the quality of the audio. 1 SOURCE SELECT Thee switches select which of AUX (1b) , I/P1 and I/P2 (6) inputs are heard at the Speaker Outputs (7) and Headphones (5). Each can be operated individually or simultaneously and in any combination.
2 MIX CHECK Phase Reverse: Inverts the polarity of the signal on the Left Channel and is used primarily to outline any phase problems that may be occurring in the mix/recording such as phase cancellation, or an unbalanced stereo signal. As the switch is toggled any phase issues will become more apparent and easier to identify. Mono: With the switch active both Left and Right stereo signals are combined into a single mono signal.
DRAWMER 5 HEADPHONE The CMC2 has a dedicated headphone output, via 1/4” TRS jack on the front face (5b), with individual headphone amplifier and level control (5a) on the front face Note that the level control is not affected by the main large monitor volume knob (3), and have no bearing on volume of the rear panel outputs (7). Just like the main volume control the headphone knob circuit design incorporates a parallelled custom quad potentiometer, for excellent channel matching and a smooth feel.
Mix Checking Tips Due to the versatility of the CMC2 some very useful techniques for checking your mix can easily be achieved, that can help improve the balance within a mix, pinpoint stereo width, phase and mono problems, and also aid when monogising. The following are a few handy tips to help eradicate problems and bring about a balance within the mix: Not too loud... Give your ears a break.
DRAWMER Monogising Check your mix in mono - often! Just because a mix sounds good in stereo doesn't mean it will sound good when the left and right channels are combined. Why should you care if your mix sounds good in mono? Well, most live music venues and dance club sound systems are mono - running the PA or sound system in mono is common practice to ensure music sounds good everywhere in the room because it removes the ‘sweet spot’ and the complex phase issues of stereo.
