Cable and Wiring Information

Use high-quality, shielded cables to connect your mixing
console, workstation or other source to your monitors. Foil-
shielded cables should do quite well. Other high quality cables
that incorporate better shielding will yield an overall higher noise
rejection, lowering your systems susceptibility to external inter-
ference. Another important tip to keep in mind when wiring your
system is to route all line level cables away from the AC and other power sources, this will reduce the
probability of having AC hum emanating from your studio monitors.

Product Cleaning Instructions

Prior to cleaning the PM841 / PM641 monitor, the power must be disconnected from the PM841 /
PM641 monitor. Once the power has been terminated, cleaning can be accomplished using a damp
(not wet) cleaning rag. A light common household cleaner can also be used, but care must be taken
not to use harsh cleaning fluids. Regular dusting or cleaning with a damp rag will keep your product
looking new for years.
