3 ELIAS PX delivers optimum sound, so you should
provide it with optimum input signals! Noise such as
humming is generally caused by defective cables, the
wrong type of cords, or unbalanced signals routed
into the mixing console. Check all signal and mains
cables.
4 Prevent distortion! Not only is it unpleasant to
your audience’s ears, it can also damage your equip-
ment. Make sure all components that are connected
directly and indirectly to ELIAS PX have sufficient
power ratings, and that they don’t distort as a result
of operating at or beyond their respective limits.
Provide an undistorted signal to the system in the
first place, so that it doesn’t have to be cleaned up
by backing off the system’s Gain knob.
5 Avoid ground loops! A ground loop can occur when
the mixer and ELIAS PX are each connected to two
different mains circuits. To prevent this problem,
always connect the ELIAS PX system and the mixing
console to the same electrical circuit (same phase!).
If your equipment hums despite this precaution, the
Ground Lift switch can be a great help.
CAUTION: Never tape over the plug’s ground
terminal - this endangers lives!
