The ChannelPlus 5600 Series are digitally-tuned video modulators that convert any baseband video and audio signal to a user-selected UHF, or Ultraband CATV. An internal quartz crystal reference oscillator and PLL circuitry ensure drift-free performance. The user selects the output frequency (channel) using the "select" button to choose which modulator and the "program" button to enter the number of the desired channel. Any TV connected to the output via coax can receive the signals, when the TV is tuned to the proper channel.

In addition, the 5600 series encodes each channel using the MTS stereo standard. Stereo sound and surround sound information will be received by any MTS compatible television receiver.

Models available:

5615 1 channel modulator

5625 2 channel modulator

5645 4 channel modulator

Option:

To connect the video and audio to a local monitor, use RCA type ‘Y’ adaptors and remove the ’LOOP’ jumper for this channel.

The model 5615 has built in loop through connectors, so it does not require the use of ‘Y’ adaptors.

Cable HRC and IRC considerations

Most cable services use IRC frequency assignments. This is the default for the ChannelPlus 5600 series modulators. However, if the cable service uses HRC or the TV appears to search for the "house channels," the modulator can be reprogrammed to use HRC assignments by entering the number “ 98”. Set to IRC by entering a “99”. Both of these settings are only used for setting HRC/IRC. Note: This setting can be entered on any modulator channel, A, B, C, or D, and affects all channel assignments for that unit. Cable channels must either be all IRC or all HRC.
