channels cannot be changed by the PRE while in “ssp” mode, the preamplifier

cannot corrupt the careful calibration of the processor’s output levels. And

since the video sources would be fed directly to the processor’s audio input(s)

at a line level, input calibration cannot be disturbed by the preamplifier.

Noise in A/V systems In some cases, connecting your audio and video systems together in this fash-

ion can result in noise, typically a 60 Hz or 120 Hz hum. The most common

cause for this noise is a “ground loop” caused by the presence of two ground

references in the system: one from the power company and another from the

cable-television company. The simplest way of solving this problem is to

break the cable company’s ground by using a 75Ω-75Ω balans (isolation)

transformer on the incoming cable line, before it reaches your television or

VCR. Contact your Proceed dealer for assistance.
