Operation Manual

Operation
Each channel has a 3-band EQ (LOW/MID/HIGH), which can be used to balance the mix of frequencies and
emphasise certain aural characteristics in the signal. Adjust these as required, noting that and overall increase may
require an equivalent reduction of the GAIN control to compensate (otherwise clipping may occur from EQ boost).
Use the PAN control to position the channel input either to the left or right side of the stereo field. This can be useful
to help separate and define sounds within a mix but be aware that extreme settings can be counter-productive by
removing the channel from certain listening positions.
Use the AUX control to feed the correct amount of the channel signal to the AUX output. This routing is “Pre-fader”
and is independent from the channel fader setting.
For CM-LIVE models, there is an EFF control, which feeds a part of the signal to the internal delay effect. Overall
controls for DELAY (time between repeats) and REPEAT (number of repeats) are on the right-hand side of the
control surface - these can be adjusted as required. An EFFECT control adjusts the overall level of the delay effect.
If external effects are to be used, plugging a jack lead into the EFFECT output defeats the internal delay effect and
acts as a mono line level “send” to the external effect unit. The output(s) from the external unit will need to be
“returned” via a mono or stereo channel and added to the mix, whereby the channel fader takes the place of the
overall EFFECT level control.
Channel faders should be used to adjust the individual levels in the mix and the MAIN fader is for overall level.
Turn down amplifier levels when changing any connections or powering down the mixer to avoid speaker damage.
USB features
For the CM-LIVE models, The USB and SD card connection is for the internal media player, which can offer
playback of compressed digital audio files through the stereo channel. When a USB pen drive or SD card with such
files on is connected via the rear panel, the player recognises this and automatically begins playback through the
stereo channel. The player status is indicated by a small backlit LCD screen, as shown below…
Transport controls allow navigation through tracks on the memory device. These are outlined below…
For CM-STUDIO models, connecting a USB A to B lead from the rear panel USB connector to a USB port on a PC
or Mac computer allows audio to be transferred between the mixer and computer. The PC or Mac will recognise the
CM-STUDIO mixer as an external USB audio device and the mixer can be selected as an audio source within
recording software and as an output to the mixer, received as a main mix return. The firmware offers plug-and-play
compatibility with Windows XP/Vista/7 and OS/X onward.
