Model CSM-42 Accepts any Remote Control


Good things come in small packages. This is a feature rich matrix switch combining analog audio, coax & optical digital audio, digital audio transcoding, and distribution capable output drivers. Don't settle for an inferior product which will degrade your signals.

The CSM42 can support the following typical applications

  • Switching 4 sets analog audio & component video to 2 displays/receivers/storage devices
  • Switching 4 sets digital coax audio & component video to 2 displays/receivers/storage devices
  • Switching 4 sets digital optical audio & component video to 2 displays/receivers/storage devices
  • Transcoding/converting Digital audio between coax and optical
  • CSM42 is designed and tested for all video signals up to and including 1080p

This unit delivers ultra clean noise performance and more bandwidth than needed for all high definition video standards. The CSM42 is also the easiest switch on the market to setup and use, and it supports all HDTV video and audio formats. Our proprietary ZeroKey technology allows switching to be performed by any key on any remote. No need for separate remotes or remote programming. The CSM42 is the optimal solution for all these applications, and the specs speak for themselves

Video distribution

CSM42 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 CSM42 switch can be controlled manually by toggle button, or by remote control. The remote control interface uses ZeroKey infrared code cloning to map any remote control key to each one of the four audio and video inputs. Here are the steps to program the CSM42 for your remote.

  1. Press the toggle button to select the input/output pair you would like to train
  2. Hold the toggle button for 3 seconds and release
  3. The LED indicator for the selected channel will now flash continuously, this means it is ready to be programmed
  4. Aim your remote control at the CSM42 and press the key you would like to use to select this input
  5. The LED indicator will stop flashing, this means the code has been stored.
  6. Repeat for the other input/output pairs (up to 16 total).

ZeroKey technology is compatible with virtually all remote controls and does not interfere with the normal operation of the remote. The best way to use this is to program the CSM42 with the same keys you normally push to switch your AV receiver or TV. The CSM42 will switch at the same time as your TV or receiver without the need for complicated macros or pushing extra buttons!

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 CSM42 can be reprogrammed as much as you like.
