Ever wished you could view full quality HDTV throughout your house without a closet full of equipment in every room?  CMX44 integrates everything you need to distribute all your HDTV video and audio sources to all the displays throughout your home. 

CMX44 is the most feature rich high performance matrix switch on the the market.  We support more signal types than the competition.

The CMX44 has the following features

1. 4 input sets, each includes the following
   • HDTV component video
   • Composite video
   • Digital audio Coax / RCA
   • Digital audio TOSLINK / Optical
   • 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. Remote IR control with Zerokey code learning ability
5. RS-232 input for serial control
6. Flash based micro controller which allows firmware updates over the RS-232 port
7. Professional quality video amps capable of driving cables up to 300'
8. Designed and tested to pass all video signals up to and including 1080p
9. Steel rack mountable case
10. Optional rack mounting ears

Flexible control options

CMX44 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 CMX44
4. RS-232 control with your existing home theater controller.  RS-232 programming guide here

Each output is individually switch-able.  You can configure CMX44 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

Video distribution

CMX44 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.

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 CMX44 can be reprogrammed as much as you like.
