Connections CONNECTIONS Inputs Cable common sense Make all connections to the Multimix 12R with the power turned off wherever possible. If you must connect or disconnect inputs while power is on, make sure the channel fader and [TRIM] are turned all the way down to avoid sudden pops and clicks which may damage speakers or other equipment. Use good-quality cable: 99% of all mixer problems turn out to be cable or connector problems. Use the best quality cable you can, for highest reliability and lowest noise. If something goes wrong, check the cable and its connection to the mixer first. If the connectors are dirty or corroded, clean them with isopropyl alcohol or other approved electrical contact cleaner before inserting them into the Multimix 12R. High quality cables are low-capacitance shielded cables with a stranded (not solid) internal conductor and a low-resistance shield. Although quality cables cost more, they do make a difference. Route cables in your system correctly by observing the following precautions: • Do not bundle audio cables with AC power cords. • Avoid running audio cables, or placing the Multimix 12R itself, near sources of electromagnetic interference such as transformers, monitors, computers, etc. • Never unplug a cable by pulling on the wire itself. Always unplug by firmly grasping the body of the plug and pulling directly outward. • Do not place cables where they can be stepped on. Stepping on a cable may not cause immediate damage, but it can compress the insulation between the center conductor and shield (degrading performance), or reduce the cable's reliability. • Avoid twisting the cable or having it make sharp, right angle turns.
