CMX1608A2 is not your average audio switch.  With over 1 TeraMACs DSP performance, it can process up to 46 audio streams simlultaneously.  CMX1608A2 features full DSP audio on all signal types (analog, digital coax, digital optical).  This includes industry leading features such as audio delay for lip sync correction, analog to digital conversion, input gain, output volume, treble/bass control, and balance.  Everything is performed using the highest quality DSP algorithms yielding CD quality sound or better on all outputs.

The entire CMX A2 product line offers unmatched upgrade capability. 

  • Programmable DSP architecture allows for new functionality to be added via firmware upgrades
  • Available in 16x8, 16x16 and 38x38 models.
  • Full 32x32 analog audio switching option using two 38x38 switches
  • Optional network audio board (NAB100) for streaming audio support

CMX1608A2 now fully supports the NAB100 network audio board.  Add 16 channels of streaming audio (smart phones, music servers, Pandora, etc) to your audio matrix.  Please follow the link for more details and select this option when ordering.  This board is also available as a field upgrade.  Network AV is the future, don't be left behind!

Intelligent audio switching

CMX1608A2 automatically solves all the headaches of dealing with multiple audio formats.  Our real time algorithms detect audio activity and format on the fly, automatically adjusting your output to always give you the best signal possible. 

Audio delay control

Audio video delay mismatch is the single largest problem in today's home theaters.  Scientific studies have shown that even slight mismatches cause major viewer dissatisfaction and annoyance.  In fact, the majority of viewers preferred watching 480p material with correct AV sync verser 1080p material with a small offset.  You can make your home theaters stand out from the competition by correcting this with the CMX1608A2!

Where does audio video delay mismatch come from?  In todays digitally processed video environment there are many sources.

  • TV signal processing:  Your digital TVs all have delay, and this keeps growing.  The TV speakers will normally be delay matched for this, but your in wall sound will not be!

  • Signal distribution:  While component video has no detectable delay, digital transmission does.  Each method varies.

  • Source material:  The editing methods used to create the digital source material do not always use proper methods to align the video and audio streams.  This is very common.

  • Source equipment:  Cable and satillite boxes often have firmware or design issues that create static mismatches.

We can show you how to use CMX1608A2 to correct all of these and provide the perfect video and audio environment.

Audio volume control

The CMX1608A2 integrates fully independent input and output volume adjustments on all audio channels using the best quality digital signal processing.  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

CMX1608A2 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 CMX1608A2 can be reprogrammed as much as you like.

Upgradeable firmware

CMX1608A2 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.
