About Audio Cables

The connections between the PEQ-450 and your studio are your music’s lifeline, so use only high quality cables. These should be 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 to the PEQ-450 correctly by observing the following precautions:

•Do not bundle audio cables with AC power cords.

•Avoid running audio cables near sources of electromagnetic interference such as transformers, monitors, computers, etc.

•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.

•Never unplug a cable by pulling on the wire itself. Always unplug by firmly grasping the body of the plug and pulling directly outward.

And most importantly, keep connectors clean. Every few months, unplug them and wipe off oxidation with a clean cloth soaked in alcohol or contact cleaner. Insert the plugs in the jacks a few times, to clean the internal jack contacts. Although Alesis does not endorse any specific product, chemicals such as Tweek and Cramolin, when applied to electrical connectors, are claimed to improve the electrical contact between connectors.

The PEQ-450 is wired according to the modern standard of "Pin 2 (tip) = Hot". Some older equipment was wired with Pin 3 hot; check to make sure correct polarity is maintained throughout your system.
