The output levels of the modulator should be the same as the output of the off-air strip amplifiers. The M860 modulators are usually combined with either the SP860 signal processor, LBS/MBS/FMS/UBS series strip amplifiers. Two methods are suggested to combine strip amplifier, modulator and processor outputs which are then amplified with the PIDA distribution amplifier serving as a launchamp.

The PHC-12Utwelve channel passive headend combiner consists of two rows of directional couplers combined by a hybrid splitter. The directional coupler combining provides high isolation (40 dB) between the inputs. Normally, the odd channels are combined on one row while even channels are combined on the other row of directional couplers. The combiner loss is 16 dB per channel.

Another method of combining signals uses three hybrid splitters per headend rack. The odd channels are combined in one splitter, the even channels in another splitter and the two splitters are combined to a single output with a third splitter. Each rack is then combined with a final splitter prior to the PIDA amplifier.
