Inputs

Cable common sense

Make all connections to the Studio 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
Studio 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 Studio 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.
