HDTV Supplys WolfPack™ Modular SDI Matrix Routers are integrated SDI video modular matrix switchers. The chassis back plane allows any SDI input to be routed to any SDI output, or the same SDI input to be routed to all SDI outputs, or any combination. It also supports HDMI in and out allowing you to cross convert between HDMI and SDI sources and output devices, like TVs with HDMI inputs. The SDI output card includes an internal DIP switch for resolution adjustment for times when the auto-adoption cannot detect an unusual display video resolution. These SDI Matrix switchers supports SDI (SMTP 259M), HD-SDI (SMTP 292M) and 3G-SDI (SMTP 424M).

The core of these Modular SDI Matrix Routers consists of either a 9x9, 18x18, 36x36 Modular Matrix chassis and its highly configurable backplane that supports either 9, 18 & 36 SDI input cards and either 9, 18 & 36 SDI output cards. You can even convert between HDMI and SDI sources and output devices, like TVs with HDMI inputs. You can control the switch via its iOS or Android app, 2-button fast switch from the front buttons, a WEB GUI control or the RS-232 serial port. The matrix does have IR and a remote control and can be controlled with its iOS and Android App as well as above. It also has optional Elan & 2-Way Control4 Drivers.

Reasons that set our WolfPack™ SDI Matrix Routers apart from others:

  1. Supports SDI (SMTP 259M), HD-SDI (SMTP 292M) and 3G-SDI (SMTP 424M) in and out cards
  2. Supports HDMI in and out cards w/SDI Conversion
  3. Supports HDBaseT CAT5 extenders to 220 feet in and out
  4. Supports a 3G-SDI loopout on the input and output SDI cards
  5. Supports 3.5 mm analog pass-through audio on the input and output SDI cards
  6. Seamless (100ms) SDI Switching
  7. Optional Crestron, RTI, Elan & 2-Way Control4 Drivers
  8. Card cages to 160x160 HDMI ins and outs
  9. Control via an iPad, Android, Web Browser, RS232 & Front Buttons
  10. 2-Power Supplys with larger matrices if a problem occurs
  11. 2-Year WolfPack Advance Replace Warranty
  12. Free Lifetime Telephone, CHAT, TEXT and Email Tech Support
  13. Other in & out cards are available like HDMI, VGA, DVI, Fiber, CVBS, YPbPr and Audio

The WolfPack™ Modular 3G-SDI Matrix Router allows switching between inputs with a clean video cut (frame-to-frame switching with no glitches). The WolfPack™ Modular 3G-SDI Matrix Routers advanced processor allows it to process up to 36-live signals simultaneously that means it can seamlessly and instantly switch (~100ms) between 36-SDI inputs and 36-outputs. Most non-seamless matrix switchers require a delay of several seconds before they can switch between devices but with this WolfPack family that wait time is completely eliminated.

WolfPack™ 16x32 SDI Matrix Switch Configuration Example:

  • 1 - 36-card in and 36 card out card cage
  • 16 - 1-port SDI input cards = 16 SDI inputs
  • 32 - 1-port SDI output cards = 32 SDI outputs
  • 20 additional SDI input slots for future card expansion to 36-inputs
  • 4 additional SDI output slots for future card expansion to 36-ouputs

By having 1-port slide in cards the matrix is exceptionally reliable as in the unlikely even there is a loss of signal you just replace the card with a spare you have purchased or order another from us. The complete matrix doesn't have to be sent to us for repair.

Our Modular SDI Matrix Routers also can support high-resolution SDI sources routed to SDI or HDMI displays, monitors, projectors, or audio receivers, etc. The EDID can be selected between seven different modes or copied from the attached displays.

The heart of the Modular SDI Matrix Routers is the WolfPack chassis backplane which allows customization of the configuration for input and output cards to match every need of the system and application. The matrix supports hot-plugs and you can change the cards while the equipment is still working.

EDID Explained: The Modular SDI Matrix Routers EDID provides for optimal source-to-screen performance. EDID will optimize the video card output for the capabilities of the end display. The EDID ghost unit enables the copying, emulating, cloning, and "learning" of EDID data from a display. Our EDID Emulator and repeater comes with predefined presets, user programmable banks, Sink EDID sniffing bank and more. Our SDI Emulator ensures proper operation, for the best performing SDI video signal between any source and display Resolves loss of video, intermittent (flashing) video, snow, or color-space (purple or red) issues.

SwiftSwitch SEAMLESS SWITCHING: Our WolfPack™ Modular 3G-SDI Matrix Router can be configured with instantaneous video switching which delivers full 3G-SDI video powered by our WolfPack engine implemented at each output port. This high-performance engine processes 3G-SDI signals by executing EDID hops and HDCP handshakes simultaneously at both the source input and the display outputs and scaling inputs for the best output resolution while setting the output clock timing and using a frame buffer to retain the input signal information for the fastest output.

Control Drivers

DirecTV Controller


HDTV Supply has successfully installed our WolfPack, WolfPackLite and our other SDI Matrix Switchers in Sports Bars, Restaurants, Bowling Alleys, Fitness Centers, Malls, Places of Worship, Data Centers, Gaming Rooms, Nail Salons, County Clubs, Casinos, Factories, Conference Rooms, Schools, Home Theaters or many other installations requiring SDI matrix switching. The reason we are told by the users is the number of features we offer compared to other companies they looked at.

This card used with our modular SDI matrix switchers can usually be integrated with many third-party control systems using the RS232 port on the back of the matrix.

For experienced AV hardware and software professionals who want to write their own drivers for 3rd party control systems from:

  • AMX™
  • Control4™
  • Creston™
  • RTI™
  • DTVGameControl™
  • Elan g!™
  • Media Switcher™
  • OnControls™
  • Savant™
  • SimpleControl™
  • SwitchItUp™
  • SAVI Control™
  • URC Control™

...and we have created a simple and very easy to use RS232 script to write your own drivers.

EXAMPLE: If you want to switch input 8 to output 1, 8, 16, the RS232 command would be 8x1&8&16. and notice the command has a period (.) at the end of the string. The matrix even replies "OK" when the right command is received and "Failed" when receiving a wrong command. Here is the RS232 User Manual if you want to write your own drivers.

How to use the info:

END USER: If you are an end user and want to have a whole-house control system from any of the above 3rd party control houses but your budget can't support the price you were quoted, do the following:

  1. Call us for a quote
  2. Once you get our quote call a 3rd party control reseller or installer in your area and tell them "Here is the hardware I want to use, please give me a quote on writing the software and installing all of the hardware at my location." You usually can save $1,000s on larger systems.

CAVEAT: We are not certified by any of the above 3rd party control systems companies nor have the necessary hardware to verify, troubleshoot and support the 3rd party writing of the code. We do warranty, though, that the RS232 script in the above RS232 Users Manual has and will work to control the matrix directly.

Q: How do the 2-power supplies work with the matrix?
For the 2 power supply system on the card cage matrix, it's a redundant system. It also can operate with just one power supply on and the other one is for back-up

Q: Do you have any tips in the unlikely event the unit fails?
Turn it OFF and then disconnect the matrix from the AC power and all cables. Pull out each board from the rear and push back in. Plug all cables back in and turn it on.
