Pre-Amp On/Off: Turn on/off amplifier function for each RF-INPUTS.
Antenna Power: Turn on/off amplifier function for each Antennas. (The input ports can supply
12V, 100mA to active antennas.)
FM Pre-Amp: Turn on/off amplifier function for FM signal.
CAP 532 is an active device which amplifies signal power, but also increase the system noise and
degrade signal quality. Misused amplifier could significantly increase distortion and reduce
signal quality. Therefore, it is necessary to know about its gain, tilt, bandwidth, and noise figure
when applying an amplifier to measure its impact in the coaxial network.
Recommendation: Turn on the Pre-Amplifier only when the input signal level is too low
(Lower than 60
dBμV)
. The user may refer to the automatic input signal power level
measurement when adding a channel on CAP 532.
NOTE: Even target channel’s signal level is low but other high levels’ channels in the same
band could saturate Pre-Amplifier and cause poor signal quality. Refer to all receiving
channels’ quality to decide turn on pre-amplifier or not.
