Front Panel Controls and Indicators, continued F6 – OFFSET Switches The OUTPUT CHANNEL switches set the output frequency for a visual carrier frequency of ‘xx.25’ or ‘xxx.25’ MHz only. The exact output signal frequency, however, is relative to the input signal frequency and any additional offset (plus or minus) set by the OFFSET switches. For example, an input signal of 229.2625 MHz (+12.5 kHz offset) and an OFFSET switch setting of ‘0’ would result in an output frequency of ‘xx.2625’ or ‘xxx.2625 MHz.

Installation CONNECTIONS AND CONTROLS – All connections to and from the HCP1550 are made through the rear panel. Figure 3 shows a typical two channel processing installation involving the converting of an off-air signal and a CATV signal. Additional channels can be processed by using additional channel processor units and either multi-port combiners or combinations of two-port combiners. INSTALLATION NOTES – Level adjustment provides optimum performance in multichannel installations.
