Ever wished you could view full quality HDTV throughout your house without a closet full of equipment in every room?  CMX84 integrates everything you need to distribute all your HDTV video and audio sources to all the displays throughout your home. 

CMX84 is the most feature rich high performance matrix switch on the the market.  We support more signal types than the competition, plus we offer unique features such as analog audio volume control and easy integration with external HDMI matrix switches.

The entire CMX product line offers unmatched upgrade capability.  Please see our section on upgrades to learn more about how our switchers can meet all your future needs as well.

The CMX84 has the following features

  1. 8 input sets, each includes the following
    • HDTV component video
    • Composite video
    • Digital audio Coax / RCA
    • Digital audio TOSLINK / Optical (6 inputs)
    • Analog audio R/L
  2. 4 independently controllable output sets, each includes the following
    • HDTV component video
    • Composite video
    • Digital audio Coax / RCA
    • Digital audio TOSLINK / Optical
    • Analog audio R/L
  3. Each output type individually controllable (advanced mode) or linked (basic mode)
  4. Full 256 step volume control on the analog audio outputs
  5. 256 step volume equalization on the analog audio inputs
  6. Programmable balance control on the analog audio outputs
  7. Remote IR control with Zerokey code learning ability
  8. RS-232 input for serial control
  9. RS-232 output for expansion and HDMI matrix control
  10. Flash based micro controller which allows firmware updates over the RS-232 port
  11. Professional quality video amps capable of driving cables up to 300'
  12. High quality Burr-Brown audio amplifiers on the analog audio outputs
  13. Designed and tested to pass all video signals up to and including 1080p
  14. Steel rack mountable case
  15. Optional rack mounting ears

Flexible control options

CMX84 can be controlled by several methods, you can choose the one the best fits your home theater control scheme.

  1. Manual control using the front panel buttons
  2. IR control using a programmable remote.  You can download the Pronto codes needed here.  The raw Hex format is here.
  3. IR control using your standard remote.  Zerokey can learn any remote keys to control CMX84
  4. RS-232 control with a PC or your existing home theater controller.  RS-232 programming guide here
  5. Use our free VSXctl windows based control software

Each output is individually switch-able.  You can configure CMX84 in one of 2 control modes:

  1. Basic mode:  Component video, composite video, analog audio, and digital audio(coax/tos) switch together.
  2. Advanced mode:  Component video, composite video, analog audio, and digital audio(coax/tos) all are switched independently

Supported by:

Audio volume control

The CMX84 integrates fully independent input and output volume adjustments on analog stereo audio using the best quality Burr-Brown line level amplifiers.  Why is this important? 

The input volume control allows you to equalize the volume from all sources to a common level.  Many satellite boxes output volume levels below nominal, so without this feature you would need to adjust the volume manually every time you switch between Cable/DVD to satellite.  After equalization, all your sources will have the same volume level. 

The output volume control is mainly used for two types of applications.  The first is to control the volume on your TV speakers from the centralized system.  It eliminates the need to use the TV remote to control volume.  The second application is for in wall/ceiling speakers.  Since volume control is built into the CMX, you can use inexpensive and high quality fixed gain multichannel power amplifiers to drive your speakers.  Not only does this simplify control, but it will save you several hundred dollars on the total solution.  Please see our forum for some examples of fixed gain amplifiers commonly used with the CMX.

Video distribution

CMX84 is the ideal amplifier for driving long video cables in your home.  Many vendors claim their products can do this, but very few can accomplish this without distortion of the video.  The most important amplifier design factors in driving long cables are source impedance matching, output connector quality, amplifier bandwidth, and amplifier current drive and slew rate.  Our amplifier uses the best components for all these, resulting in the best signal distribution you can get.  If you are interested in video distribution, please see our information page for more tips on optimizing your network for zero distortion.

ZeroKey technology

The remote control interface can use ZeroKey infrared code cloning to map any remote control key to each of the inputs & outputs.   ZeroKey technology is compatible with virtually all remote controls, and does not interfere with the normal operation of the remote.  Please see our quick start guide for a description of how to program for an IR remote using ZeroKey.

ZeroKey programming is stored in flash memory, and you will not need to reprogram even if you lose power.  If you buy a new remote in the future, don't worry, the CMX84 can be reprogrammed as much as you like.

This product is covered by our 100% risk free guarantee and our standard warranty.

HDMI expansion capability

The CMX84 has the ability to seamlessly add HDMI matrix switching capability.  Simply purchase one of our HMX series rack mountable HDMI matrix switches and connect the RS-232 port from the HMX switch to the expansion port on the CMX84.  You will be able to switch the HDMI matrix through the same control interface you use to switch the CMX84.  No need for a separate remote or RS-232 controller.

Upgradeable firmware

CMX84 supports firmware updates over the RS-232 port.  Future updates will add the capability to control all our new products over the expansion port.  Follow this link for more information.
