HDTV Supplys 4x12 HDMI Matrix Switch Over Coax Cables switches and extends 4-HDMI video and stereo audio signals to 12-widescreens over a signal point-to-point coax cable to the TVs that can be up to 1,500 feet away on a single home run RG6 coax cable. The 4x12 HDMI Matrix Switch Over Coax cables provides digital coding processing for the HDMI signals with our DTV technology. The 4x12 HDMI Matrix Switch Over Coax Cables adopts HDTV Supplys RF modulation technology to transmit the 4 - HDMI signals up to 12 - TVs via a coaxial cable per the TVs HDMI input, not the coax input.

NOTE: The 4-HDMI transmitters are very powerful so it can be part of the system to go 1,500 feet. If your distance from your source device(s) are 300 feet, or less, to the passive coax splitter you will need up to 4 of the above 10dB attenuators on each transmitter coax cable. If you need more info, call us.

The 4x12 HDMI Matrix Switch is a true HDMI matrix switch allowing any of the 4-inputs to be routed to any of the 12-outputs, or the same input to be routed to all outputs, or any of the millions of combinations.

Where should this 4x12 HDMI Matrix Switch Over Coax Cable be used?

  1. Shopping malls where inputs and outputs are rarely changed
  2. Factory complexes where inputs and outputs are rarely changed
  3. Bars and restaurants where inputs and outputs are rarely changed
  4. Campuses where inputs and outputs are rarely changed
You set the DIP switches and change the DIP switches when you want to send different sources to different TVs. See the above FAQ for examples.

What set this 4x12 HDMI Matrix Switch Over Coax apart from other HDMI Matrix switchers?

  • The source devices can be over 1,000 feet away from the TVs
  • You probably can use the home run coax cables already installed
  • You set it once with the DIP switches and change the DIP switches when you want to send different sources to different TVs
  • The cost is very low if your in and out switching do not change much as the switch is changed by each individually DIP switch on each transmitter and each receiver
NOTE: The matrix setup uses multiple transmitters and multiple receivers and is setup via the 8-DIP switches on each transmitter and receiver. The HDMI Matrix Switch Over Coax cannot be controlled any other way.

4x12 HDMI Matrix Switch Over Coax Cables Features:

  • Preconfigured for an 4-HDMI in and 12-HDMI out matrix switch. The DIP switches will be set at the same so you will need to configure their settings per the user manual and your TV locations.
  • Contains 4-transmitters (TX) and 12-receivers plus their AC adapters (24).
  • Supports HDMI resolutions up to 1080p/60Hz.
  • The transmission distance up to 1,500 feet with RG6 Quad Shield home run coaxial cables without any need of amplification.
  • Supports 80 channels via the DIP switches with frequency ranges of 139MHz to 950MHz.
  • The matrix uses the broadcast signal transmission mode, only one line can transmit 48 channels of high-definition video signal at the same time.
  • The use of digital TV communication protocol, anti interference and error correction capability is very strong.
  • Installs in minutes.
  • Includes 16-DC5V/1A power adapters

4x1 and 1x12 HDMI to Passive Coax Splitter Specs:

  • The coax bi-directional splitters provide a 1 GHz bandwidth and are ideal for this application.

4x12 HDMI Matrix Switch Over Coax Cables FAQ:

  1. In normal conditions the transmission distance w/o amplification can be up to 500 meters or 1,500 feet using SYV-75-5 coaxial cables
  2. The signal strength will become weakened after adding DTV network mixers and multiple outputs as used in splitter and matrix applications.
  3. If the signal frequency is high, the transmission attenuation is greater. So choose low channel for long-distance transmission.
  4. When the transmission distance is short (less than 100 meters or 33 feet) the signal may be too strong and the receiver will protect the strong signal and display "NO SIGNAL" to the display. If that is the case you should choose a higher channel via DIP switches or add an attenuator in line with the coaxial cable for signal attenuation.

Here is an example of setting up an HDMI matrix over coax.

EXAMPLE 1: We have 1-DirecTV satellite receiver and 1-DVD player connected to 4-widescreens that have 500 feet home run RG6 Quad-shield coax cables between the matrix and the widescreens. You will need the users manual for this.
  1. Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
  2. Set the DVD player HDMI transmitter to CHANNEL 2 ID (00000010)
  3. Set widescreens 1 and 3 HDMI receivers to CHANNEL 1 ID (00000001)
  4. Set widescreens 2 and 4 HDMI receivers to CHANNEL 2 ID (00000010)
You now have set up the following:
  1. The DirecTV is now displaying on widescreens 1 and 3
  2. The DVD is now displaying on widescreens 2 and 4
EXAMPLE 2: In another example we will have 1-DirecTV satellite receiver connected to 4-widescreens that have 500 feet home run RG6 coax cables between the matrix and the widescreens.
  1. Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
  2. Set the 4-widescreens HDMI receivers to CHANNEL 1 ID (00000001)
You now have the DirecTV displaying on all 4-widescreens as you have changed the frequency to match the DirecTV transmitter box. The important thing to know is if you are constantly changing ins and outs the HDMI transmitters and receivers DIP switches must be accessible as this is the only way to control the coax matrix. Its design is best used where changing ins and outs is minimum. Full control HDMI matrix switchers operated via a remote control or front panel controls can be seen the the above SIMILAR tab.

Hard to understand, do this...hand draw a diagram of the source devices on the left, the matrix in the middle and the widescreens on the right. Mark the cable lengths and what source you want to go to what widescreen. That will get you close to how to set the DIP switches (frequencys). You have 80-input and output frequencys available to you.
