Fader Cleaning
With heavy use in harsh environments, the faders may need
lubrication. This treatment extends longevity and can make used
faders as good as new. The fader assembly must be removed from
the MP 2 for proper cleaning. We recommend any of the follow-
ing cleaning solutions:
Caig DeoxIT FaderLube F100 spray lubricant (www.caig.com)
Caig DeoxIT FaderLube F5 spray cleaner (www.caig.com)
CRC 2-26 (www.crcindustries.com)
Order DeoxIT® from:

IMPORTANT NOTE
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units some-
where. Your mission, should you accept it, is to discover how your particular system wants to be grounded. Here are some things to
try:
1. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord grounding
pin or the rack screws to another grounded chassis like the amplifier.
3. Units with outboard power supplies do not ground the chassis through the line cord. Make sure that these units are grounded
either to another chassis which is earth grounded, or directly to a known ground by means of a wire connected to a screw on the
chassis with a star washer to guarantee proper contact.
Refer to the RaneNote, “Sound System Interconnection” included with this manual for further information on grounding.
