HDTV Supplys 4x8 HDMI Matrix Switch Over Coax Cables switches and extends 4-HDMI video and stereo audio signals to 8-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 4x8 HDMI Matrix Switch Over Coax cables provides digital coding processing for the HDMI signals with our DTV technology. The 4x8 HDMI Matrix Switch Over Coax Cables adopts HDTV Supplys RF modulation technology to transmit the 4 - HDMI signals up to 8 - 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 got 1,500 feet. If your distance from your source device(s) are 300 feet, or less, to the passive coax splitter you will need 4 of the above 10dB attenuators on each transmitter coax cable. If you need more info, call us.
The 4x8 HDMI Matrix Switch is a true HDMI matrix switch allowing any of the 4-inputs to be routed to any of the 8-outputs, or the same input to be routed to all outputs, or any of the millions of combinations.
Where should this 4x8 HDMI Matrix Switch Over Coax Cable be used?
Shopping malls where inputs and outputs are rarely changed
Factory complexes where inputs and outputs are rarely changed
Bars and restaurants where inputs and outputs are rarely changed
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 4x8 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 DIP switches on each transmitter and receiver. The HDMI Matrix Switch Over Coax cannot be controlled any other way.
4x8 HDMI Matrix Switch Over Coax Cables Features:
Preconfigured for an 8-HDMI in and 8-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.

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
Installs in minutes.
Includes 12-DC5V/1A power adapters
4x1 and 1x8 HDMI to Passive Coax Splitter Specs:
The coax bi-directional splitters provide a 1 GHz bandwidth and are ideal for this application.

4x8 HDMI Matrix Switch Over Coax Cables FAQ:
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
The signal strength will become weakened after adding DTV network mixers and multiple outputs as used in splitter and matrix applications.
If the signal frequency is high, the transmission attenuation is greater. So choose low channel for
When the transmission distance is short (less than 100 meters or 330 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.
Our 4x8 HDMI Matrix Switch Over Coax Cables offers solutions for noise, space and security concerns, data center control, information distribution, conference room presentation, school and corporate training environments.
NOTE: This HDMI Coax Extender includes a SEND unit and its AC adapter and RECEIVE units and their AC adapters and all must be used. It cannot work with only one box and needs both boxes and must be used in pairs. It cannot be used to convert an incoming coax signal to an HDMI signal or vice versa. Think of it as a long HDMI cable.
Q: Does this 4x8 HDMI Matrix Switch Over Coax Cables have a remote control?
A: No, its inputs and outputs are set with the DIP switches on the side of each transmitter and receiver.
Q: What are the benefits of different frequencies?
The 4x8 HDMI Matrix Switch Over Coax Cables supports 80 channels of frequency ranges from 139MHz to 950MHz. If you use many transmitters and many receivers, only the transmitter and receiver have the same frequency as it can receive the signal. This function and anti-interference and error correction allows the unit to work flawlessly.
Q: Any tips you can give me on the install?
A: In-house and existing passive splitters drop the signal strength in half, or more, so delete all of the splitters and wire this device directly as it won't work with coax splitters. They should NOT be used in conjunction with connector adapters, signal processors, switches or amplifiers between the Source and Display device. This HDMI to Coax Splitter sends only one HDMI signal to a TV with the receive unit at the TV. It does not work any other way. If you are trying to send one coax signal to a TV with an HDMI input it won't work. One set includes a transmitter and a receiver set. Think of it as a long HDMI cable.
Q: Sometimes we see a message on the screen "Searching for TX", what is that?
A: That usually happens when the source is turned off or in a standby mode with the HDMI connector not outputting any signal. The (TX) transmitter or receiver is looking for a hot HDMI signal on its input.
Q: Does this 4x8 HDMI Matrix Switch Over Coax Cables support 3D or 4K or remote IR?

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.
Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
Set the DVD player HDMI transmitter to CHANNEL 2 ID (00000010)
Set widescreens 1 and 3 HDMI receivers to CHANNEL 1 ID (00000001)
Set widescreens 2 and 4 HDMI receivers to CHANNEL 2 ID (00000010)
You now have set up the following:
The DirecTV is now displaying on widescreens 1 and 3
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.
Set the DirecTV HDMI transmitter to CHANNEL 1 ID (00000001)
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.
