What Is a WolfPack Fixed HDMI Matrix Switcher?

A WolfPack Fixed HDMI Matrix Switcher is a single-chassis device that routes any HDMI source — such as a cable box, satellite receiver, streaming player, or computer — to any TV or display in a building, simultaneously and independently. Unlike an HDMI splitter (which sends one source to many screens) or a simple HDMI switch (which selects one source for one screen), a matrix switcher lets you show a different channel on every TV at the same time. HDTV Supply has sold WolfPack fixed matrix switchers to sports bars, restaurants, hotels, churches, schools, and commercial AV integrators since 2000.

Fixed vs. Modular: Which Do You Need?

WolfPack comes in two families: Fixed and Modular. Fixed matrix switchers have a set number of inputs and outputs built into one box — for example, 4 inputs × 4 outputs (4×4) or 8 inputs × 8 outputs (8×8). They are plug-and-play, rack-mountable, and the right choice when your input/output count won't change. Modular matrix switchers use a chassis with swappable I/O cards, scaling from a few ports up to 80×80 or beyond. If you know exactly how many sources and screens you need today, a fixed unit is typically lower cost and simpler to deploy.

Available Fixed WolfPack Configurations

HDTV Supply offers WolfPack Fixed HDMI Matrix Switchers in the following sizes:

  • 4Ă—2 — 4 sources to 2 displays
  • 4Ă—4 — 4 sources to 4 displays
  • 8Ă—8 — 8 sources to 8 displays
  • 8Ă—9 — 8 sources to 9 displays
  • 16Ă—16 — 16 sources to 16 displays
  • 16Ă—32 via CAT6 — extends signal up to 450 feet over CAT6 cable

Select models include built-in video wall processing, multiview, and picture-in-picture (PIP) — allowing two or more sources to display on a single screen simultaneously.

Control Options for Fixed Matrix Switchers

Every WolfPack Fixed HDMI Matrix Switcher supports multiple control methods so you can integrate it into any environment:

  • Front-panel buttons — manual source switching directly on the unit
  • IR remote control — included with most models
  • RS-232 serial control — for integration with Crestron, Control4, AMX, and similar systems
  • TCP/IP (LAN) control — send hex commands over your network from any device
  • Web GUI — browser-based interface for switching without additional software
  • Free iOS and Android apps — available for select WolfPack models

For RS-232 hex command strings and TCP/IP control protocols, see our WolfPack HEX Code Reference and TCP/IP Control Guide.

Frequently Asked Questions

What is the difference between a fixed HDMI matrix switcher and a modular HDMI matrix switcher?

A fixed HDMI matrix switcher has a set number of HDMI inputs and outputs built into a single unit — for example, 8 inputs and 8 outputs. A modular matrix switcher uses a chassis with interchangeable I/O cards, so you can configure it for many different port counts and expand it later. Fixed units are simpler and more affordable; modular units offer flexibility for larger or changing installations.

Can a WolfPack fixed matrix switcher show different channels on different TVs at the same time?

Yes. A matrix switcher routes any input to any output independently. In an 8×8 configuration, all 8 displays can show 8 completely different sources simultaneously, or multiple displays can share the same source — in any combination you choose.

Can I control a WolfPack fixed matrix switcher from a Crestron or Control4 system?

Yes. WolfPack Fixed HDMI Matrix Switchers support RS-232 and TCP/IP control, which are standard integration protocols supported by Crestron, Control4, AMX, and other third-party control systems. HDTV Supply provides hex command strings and driver documentation to support custom integrations.

What resolution do WolfPack Fixed HDMI Matrix Switchers support?

Resolution support varies by model. WolfPack fixed matrix switchers are available in 1080p (Full HD) and 4K 30Hz configurations. Select 4K models also support HDR and HDCP 2.2. Always check the individual product specification sheet for confirmed resolution, color depth, and HDCP version.

How far can I run HDMI from a WolfPack fixed matrix switcher?

Standard HDMI outputs on fixed matrix switchers support runs up to approximately 25–50 feet depending on cable quality and resolution. The WolfPack 16×32 model transmits over CAT6 cabling for distances up to 450 feet per run. For longer distances with other fixed models, HDMI extenders can be added at each display.

What is the best HDMI matrix switcher for a sports bar?

For sports bars with up to 16 TVs, a WolfPack Fixed 16×16 HDMI Matrix Switcher is a popular choice — it handles 16 independent sources (cable boxes, satellite receivers, streaming devices) and routes any of them to any TV. For larger venues with 20–80+ TVs, HDTV Supply's WolfPack Modular Matrix Switchers or AV Over IP systems are typically the better fit. Call 833-WOLFPACK (833-965-3722) for a free consultation.
