This ChannelPlus 3400 Series video distribution system contains digitally-tuned
video modulators that convert any baseband video and audio signal to a user­selected UHF, or Ultraband CATV channel. 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 whichmodulator 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.

Models available:

3425 2 channel system
3445 4 channel system

Cable HRC andIRC considerations

Most cable services use IRC frequency assignments. This is the default for the ChannelPlus
3 . However, if the cable service uses HRC or the TV appears to search

400 series’modulators
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. : 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 IRC or

HRC.

Common questions

Can an amplifier be used on an output to drive signals over longer cable paths?

The IR remote controlfeature will be defeated ifanexternal amplifier is used.

Can a splitter be used on one or more outputs in order to add more TVs?

model 3425/3445 Multi-room Video Distribution System is a pre-engineered system providing
optimum signal levels to each TV for clear, crisp picture quality. Each time a splitter is added,
there is lowering of signal level called insertion loss. Insertion losses upset system
performance. Additionally, the IR remotecontrol feature will be defeated.
