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.
