Connecting To Equipment With Xlr Inputs And Outputs; About Audio Cables - Alesis ModFX Reference Manual

Connecting to equipment with XLR inputs
and outputs:
If you are connecting the Philtre to a product with XLR balanced
inputs and outputs, you will need to convert this signal to a 1/4"
unbalanced connector. Make sure that Pin 2 of the XLR
connector is connected to the Tip of the 1/4" adapter or cable.
Watch out for high levels, however: some XLR sources put out
levels close to the maximum the Philtre can accept (about +12
dBu) even when its trim is at minimum. Lower the level of the
source if the [SIGNAL] LED flashes red.

About audio cables

The connections between the Philtre 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 Philtre 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.
