This WolfPack Seamless HDMI Matrix Switcher allows switching between inputs with a clean video cut and frame-to-frame switching with no glitches. The WolfPacks Modular HDMI Matrix Switcher advanced processor allows it to process live signals simultaneously which means it can seamlessly and instantly switch (~100ms or 0.1 second) between HDMI inputs and outputs. Most non-seamless HDMI 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.

100ms Seamless HDMI Switching: This WolfPack™ Seamless HDMI Matrix Switcher delivers 100ms instantaneous video switching at each port. This high-performance engine processes HDMI signals by executing EDID hops and HDCP handshakes simultaneously at both the source input, the display outputs and scales the inputs for the best output resolution. It sets the output clock timing and uses a frame buffer to retain the input signal information for the fastest output.

Separate Embedded Audio In and De-embedded Audio Out: The Seamless Matrix Switcher allows you to display video with separate audio coming from another audio source as it supports embedding the audio on the HDMI input cards 3.5mm audio connector and then de-embedding the audio on the HDMI output cards 3.5mm audio.

Hardware Scaling via DIP Switches on both in and out cards: The 8-pin DIP switch on the cards are for the manual scaling up/down. Each HDMI card has a 8-pin DIP switch to select multiple resolution settings to conform to your HDMI source devices and the HDMI destination devices.

Supports EDID Management: Ensure that even the most difficult display can receive audio and video with eight programmable memory presets loadable to any source connected to the matrix.

HDTV Supply has successfully installed our WolfPack, WolfPackLite and our other HDMI 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 HDMI 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 modular HDMI matrix switcher 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 shows "ERR" 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.

Our engineer in China made this video to show our 4K 60Hz Modular Matrix Switcher with a 4K 60Hz HDMI 2.0 input and an HDBaseT output to the POC HDBaseT receiver. It shows our seamless (100ms) switching without any black or blue screen interruption during the HDMI switching. It also shows our 3.5mm audio embedded and de-embedded function, the iPad control and the quick 2-key switching.

Below is a video of the WolfPack 9x9 card cage model showing the fast switching speed and its features. The larger card cage models will operate exactly the same but will allow more input and output cards.

They are:
18x18: 4U - 482 x 390 x 178mm - 18.97 x 15.35 x 7.01 inches (L/W/H)

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.

Q: How is HDBaseT technology different than others?
Unlike other HD distribution technologies, HDBaseT is the only technology which enables CAT5/6/7 connectivity from 70 meters to 100 meters, depending upon the specific product, for uncompressed full HD multimedia content and up to 100 watts of charging power via a single cable. HDBaseT is optimized for video applications and can connect all HDBaseT enabled home entertainment devices. Also, HDBaseT technology has the capacity to deliver double the resolution available today to future 2K and 4K formats. Other existing solutions also require a specific cable and/or a new proprietary connector while HDBaseT utilizes the existing Ethernet infrastructure. These WolfPack HDBaseT matrix systems have with (POC) Power Over Ethernet so you don't need AC adapters.

HDMI HDbaseT Extender Helpful Tips & Recommendations:

  • Keep cables away from any equipment with an electromagnetic wave, e.g., mobile phone, microwave, radio equipment, fluorescent lamp, high voltage power lines, etc.
  • CAT5/6 cables should not exceed 220 feet or (70m).
  • Please adhere to the TIA/EIA568B standards when terminating network cables in the field.
  • Shielded CAT5/6 with metal RJ-45 connectors are recommended to safeguard against random video flashes caused by electromagnetic interference (EMI).
