Setting up

The following pages give a full description of the connectors and their purpose. You should study this carefully before you power up the mixer to ensure you get the best performance from the CDM10:4.

Cables & Connectors

Always use good quality cables and connectors. Over 75% of all problems with DJ systems are simple connector issues. Don’t get caught out.

Switching on your system

Always turn on your mixer and input devices before you turn on the amplifier. The CDM10:4 has been designed not to harm your amplifiers or speakers if you turn them on first, but this may not be true of the inputs plugged into the mixer. Play Safe and always turn your amplifiers on last.

Power Supply

The power supply for the CDM 10:4 is built into the mixer and is supplied with a BS approved IEC mains plug specifically for use in the UK. If it does not match the power socket you wish to use check with your dealer before you plug it in. It is possible you could damage your mixer if it is not the correct version.

Crossfader

This is commonly the most used feature on your mixer. Even though a great deal of care has been taken in the choice of components for this function, it is the most likely thing to wear out first on your mixer. So we’ve made it quick and easy to replace.

Connection Guide

Operation

Check mains for correct voltage as indicated near to the IEC mains inlet on the rear panel
Connect to mains supply using the IEC cable provided
Connect the Main unbalanced RCA and/or balanced XLR outputs to the main PA and ensure that the volume levels are turned down to avoid damage
Connect the BOOTH outputs to powered booth monitors or separate PA zone · Connect any turntables to the RCA PHONO inputs on CH.2 and CH.3
For external audio processing or effects, assign the required channel using AUX ASSIGN and connect SEND to inputs of the processor and RETURN to outputs of the processor
If the unit is to be rack-mounted, it is possible to unscrew the input connector section and
rotate 180° for underside connection, taking care not to disconnect any internal wiring
Earth turntables to the case grounding point on the rear panel · Connect CD players or other line level audio sources to the CD inputs
Connect CD, CD+G, laptop, TV decoder, DVD or MP3 players to LINE inputs
Connect DJ mics to the top panel jack/XLR combo sockets and rear jack sockets if needed
If required, connect personal MP3 player to top panel 3.5mm input
Connect headphones to the HEADPHONE jack
Connect rear panel USB connections to a PC or Mac for computer audio playback/recording · With MASTER LEVEL down, switch the power on
Ensure microphone levels are turned down · Gradually increase MASTER LEVEL and channel levels to check input signals
Ensure that the input selectors are moved to select the relevant input being played
Be aware that the CROSSFADER operates across assigned channels setting to centre position allows both channels through moving to either side favours that channel
Gradually increase microphone channel levels to check microphone signals.
Monitor each stereo channel via headphones selecting using the CUE switches
Whilst a channel is on CUE, adjust the GAIN so that LED meters show a full signal without showing “in the red” (overload)
Adjust Hi, Mid and Lo EQ settings to the desired tonal effect for mics and audio sources
When using DJ mics 1 and 2, push the ON AIR switch and if required, push MIC OVERRIDE to drop the music level whilst talking. Sensitivity and Depth of this function are adjustable.
Playback from PC or Mac computer is available through 2 USB ports, which act as Plug & Play audio devices
Connecting these to the computer will work the same as connecting 2 external sound cards. Once automatic installation is complete, select these as playback hardware in the relevant software menu and select “USB” on the CDM10:4 channel selector for playback.
The USB interfaces can also be selected as recording devices to record mixes from CDM10:4 (consult your software manual for further installation and setup details)
