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. Models available: 3425 3445 2 channel system 4 channel system Common questions C D pll frequency control A BCD Remove jumper for Hi-Z (See manual) Can a splitter be used on one or more outputs in order to add more TVs? … No. The 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 remote control feature will be defeated. CH A B POWER 15VDC 600mA CH C A program CH B CH D model 3445 four channel integrated modulator and distribution system OUTPUT select Most cable services use IRC frequency assignments. This is the default for the ChannelPlus 3400 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. Can an amplifier be used on an output to drive signals over longer cable paths? … No. The IR remote control feature will be defeated if an external amplifier is used.

Check that the TV and the modulator are tuned to the same channel. For example, if the modulator is broadcasting on UHF channel 16, make sure the TV is on UHF 16 rather than CATV 16. UHF 16 and CATV 16 are at different frequencies. Sample System Diagram SATELLITE RECEIVER In this system, CATV or antenna channels are available on all TVs. In addition the following channels have been added: Weak ChannelPlus UHF channel … If the TV has a separate UHF input, be sure that it is connected. Audio volume is low … The left and right audio inputs are combined for monaural. For proper audio level, both right and left inputs must be used. If you have a mono source, connect it to both right and left inputs using an RCA ‘Y’ connector. No color on ChannelPlus channels … You may have chosen the incorrect cable standard. Not all televisions can accommodate the 1.25MHz frequency difference between the H and I cable standards. See the section on programming. Infrared Remote Control Problems … Use the red IR DATA light on the side of the modulator section as a trouble shooting aid. This light will blink as remote control signals are relayed.

Often, you can cure the problem with a simple attenuator. Use a variable attenuator and try to find a signal level where the interference just disappears. Sometimes, the problem is one station that is far stronger than the rest. In this case attenuating all of the signals with a simple attenuator will cause the desired stations to be weak (snowy). In this case you must reduce the strength of only the offending station. A common FM trap will help if the problem is a nearby FM tower. If the problem is a nearby TV station, often the station management can provide suitable filters. Video/audio outputs CH C Herringbone interference on ChannelPlus channel (diagonal lines) ... You may have chosen a channel number that is not completely vacant. Distant UHF stations may be un-watchable, but will cause interference if you try to create a new channel at the same frequency. Also, cable companies often have extra signals where there should be none. Try moving the ChannelPlus channel to another number. You may have to add a low pass filter to remove cable company noise. If a filter does not work, try adding a DC-block to remove common mode interference. VIDEO Use only shielded 75 ohm coax LEDs blink ... You need to have one unused channel space between channels. The display will blink if you have made an ‘illegal’ choice. See the section on programming. AUDIO L AUDIO R VIDEO AUDIO L Model 2173 IR emitter repeats what the IR target ‘sees’ in the other room. AUDIO R Video/audio outputs Video/audio outputs Attach the IR emitter directly over the IR sensor. 12:00 VCR RG6 coax preferred VCR DVD If the light is on constantly, one or more IR targets is receiving electrical or optical noise. At the modulator section unit, begin to disconnect the outputs to the TVs until the IR DATA light goes off. This will tell you which IR target is the source of the noise. Next cover the front of the offending IR target. If the IR DATA light turns off, the IR target is ‘seeing’ a source of IR noise, such as a solid state flourescent lamp. If the light does not go out, the problem may be radiated electrical noise from the TV. Reposition this IR target. If repositioning the IR target does not help, the TV may be conducting noise from its input. Place a DC block between the IR target and the TV. If the IR DATA light seems to indicate proper operation, but the component is not being controlled, the IR emitter may be mis-located. Be sure the emitters are in front of the IR sensor.
