Essential Info

This 4-channel s-video modulator allows complete MTS stereo encoding and S-video inputs in a full component size rack mountable case. Not only can you get access to cable TV, satellite TV or a security camera on every TV in the house, now you can experience it with stereo audio. Fully compatible with Dolby Pro Logic this modulator will pass stereo sources to all remote television locations. Best of all, this is the first modulators Channel Plus has offered that use the superior s-video connectors (composite to s-video adapters are included). For loop-though connections where the signal goes into the modulator then on to a local TV or audio receivers, an output jack is provided.


What's Included

  • 4-Channel S-Video Modulator with MTS Stereo Sound - SVM-24
  • More Info

    When distributing satellite signals and DVD movies think of the loss in viewing quality if you didn't have stereo sound. This 4-channel s-video modulator delivers stereo and are compatible with Dolby Pro Logic to enhance your viewing experience. Watch movies and programs the way they were intended!

    Get access to cable TV, satellite TV or a security camera on every TV in the house — and the ability to remotely control the component with any remote control — with this 4-channel modulator with IR Output. The modulator also has loop-out capabilities and integrated IR control offer IR emitter output jacks and the ability to remotely power 7712 Video Distribution Panels from up to 75' away, eliminating the need to run a power line to the panel.

    One of the challenges of having one A/V device servicing multiple TVs is controlling that device. Unless you like running back to the DVD player (to pause the movie) or satellite receiver (to change the channel), you'll need a way to get the remote control signals back to the source device. These modulators have integrated IR control engines that can manage all this. Just mount a IR Wall Plate (#7713WRA) in a room and plug in an IR Sensor (#7718WR) and you'll be able to send remote control signals back to the modulator over coaxial cable. Plug an IR Emitter (#8170 or #8171) into one of the four jacks and attach to the front of the AV device. These modulators with IR Outputs work with both 12-volt and 5-volt IR systems and accessories.

    Why You Need a Modulator
    Modulators can convert any baseband video and audio signal to a user-selected UHF or Ultraband CATV TV channel. Internal quartz crystal reference oscillators and PLL circuitry ensure drift-free performance. The user selects the output frequency (channel) using 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. This modulator with IR Output offers 75-ohm termination jumpers to loop-through the video and audio signals. The loop-through connections incorporate active termination loop outs eliminating the need for jumpers or specialized Y adapters. The loop out does not affect the quality of the audio/video signal. Includes power supply.

    Been a Longtime User of Channel Plus Products Works as designed. However some of the S-Video/Composite adapters were faulty on this recent purchase.

    After purchase contacted Channel Plus tech who confirmed that it does NOT have an integrated IR engine. Requires the $200 Video Distribution Panel in order to use IR over coax feature.
    SEAN -- great falls, VA   4/12/2010
    Fitted into the rack easily and simply. Works well.
    JEFF -- bloomington, IL   2/15/2010
    S video unit didn't work right with Dish network and comcast units. The regular composite unit works great. S video was more $$ than regular composite unit.
    BRUCE -- fitzroy harbour, ON   1/31/2010
    Works great out of the box
    ROY -- merrimack, NH   11/29/2007
    I didn't see many, or perhaps any, other 4-input video modulators on the market, and certianly no others that will take S-Video inputs and maintain stereo sound. This unit puts out high quality video and sound, is very easy to use, and fits nicely stacked with other components. The only down side is that it interferes with at least one of the high def channels from my cable provider. The manual for the unit even states that, "The high output of the Channel Plus modulator can over drive many RF amplifiers. Reduce the RF signal using an attenuator. I was able to resolve this issue by reconfiguring my distribution system, but it's an issue you'll want to be aware of if you have a single amplifier/distribution point.

    excellent worked perferctly out of the box
    KENT -- minneapolis, MN   9/20/2004
    Great, I should note that it was hard to locate this product in your mix online originally...I knew I wanted SVideo, stereo ch modualtion - but it still took a while to wade through all the options.
    TOM -- henderson, TN   6/25/2004
    Great functionality for those needing Loop input/outputs on SVIDEO - This box reduced a number of cables in my home theatre setup. Thanks for a great product
    DAVID -- harrisburg, NC   2/12/2004
    I have installed this and I am very happy with it. It is somewhat expensive, but I love having everything rack mounted.
