Operating Guidelines
Below is a chart showing the proper operation level for the
CA-30/870AR
. Please note the listed performance criteria is
for SPECIFIC numbers of channels, and must be de-rated accordingly when inserting additional channels. Also note the
amplifier’s gain does not change. However, as the number of channels increases from 7 channels, the input level
(hence, the output level) must be reduced. Exceeding the input levels listed below will cause intermodulation and
picture distortions.
