General Do’s & Don’ts

There are a few general Do’s and Don’ts thoughts that you should become familiar with if you have not had a
great deal of experience with professional audio systems.
Cables & Connectors - Always use good quality cables and connectors. It might seem expensive when you first
look at it, but the first time you have a problem in front of an audience you’ll curse the day you didn’t make that
small investment. Over 30 years in the business has taught us that over 75% of all problems with DJ systems
are simple connector ones. Don’t get caught out.
Switching on your system - Get into the habit of turning on the mixer and all the inputs to it before you turn on
the amplifiers. The CDM8:4s has been designed not to harm your amplifiers or speakers if you turn the
amplifiers on first, but this may not be true of the inputs plugged into the CDM8:4s Mixer. Play safe; always turn
on your amplifiers last.
Power Supply - The power supply for your CDM8:4s is built into the mixer and will be fitted with a mains plug
specifically for the mains supply in your country. 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
for your mains power supply. Worse still, it could be unsafe. Don’t take chances with Mains Power - it can kill.
Crossfader - The crossfader is the most used feature on your mixer and great care has been taken in the choice
of components for this function. Even so, it is the most likely thing to wear out first on your mixer, so we’ve made
it quick and easy to replace. Don’t get caught out, always carry a spare.
