Excellent Four Device Modulator For Video Distribution - Less Expensive Than Blonder Tongue With Equivalent Results.
This review is from: Channel Plus - 4 Channel Video Modulator w/ IR (5545)
Pros: Will also power the DA-550 amplifier and four 2100A wall plates and IR targets. also has outputs for four IR emitters. Strong performance offering exceptional picture clarity of Analo signals means you get perfect picture transmission from up to four RCA cable input devices (VCR, DVD, Satellite receiver, camera, etc.) without multiple component interference. Sound reproduction is also great but mono only. Great for security video cameras. Video can be placed on selected Analog channels (but not on adjacent channels). Makes hidden components a snap using IR passing capability provided in unit.
Cons: Not stereo sound. Both RCA audio ports must be supplied with supplied audio signal or sound volume will decrease. Previously available stereo signal re-encoder component is no longer available.
Other Thoughts: Runs slightly warm - keep away from heated and/or enclosed areas. May require attenuation on the output. Must set otput channels per supplied instructions. Be sure to use blocking capacitors as needed. Also, only use RG-6 cabling with newer compression fittings. Can use coaxial power or power port in unit and supplied power transformer. (Can be powered from a 2010 powered wall plate by 75 Ohm cable) A "notch" filter or "low pass" filter may be needed on the Off-Air antenna or Cable distribution to give undisturbed perfect signals from the output modulated channels - use one that clears only unwanted or un-needed channels from the Off-Air or cable distribution.
