Product Overview
HDTV Supply's WolfPack™ 4K@60Hz 8x8 Modular HDMI Matrix Switcher Chassis (Part No. HDTV-MM08-4K60) is a professional-grade, rack-mountable AV distribution system engineered for demanding multi-source, multi-display installations. Built on a 16x16 backplane architecture, the 8x8 chassis accepts up to two slide-in input cards and two slide-in output cards — each providing four ports — delivering a fully configurable 8-input by 8-output routing matrix in a compact 4U rack footprint.
Unlike fixed-port matrix switches, this modular design allows you to mix and match HDMI input cards, HDMI output cards, and HDBaseT CAT6 extension cards within the same chassis. This eliminates the need for external signal converters and lets you build exactly the system your installation requires — whether you need all direct HDMI connections, all long-distance HDBaseT runs over CAT6, or a hybrid of both.
Every signal path supports 4K resolution at 60 frames per second (3840×2160@60Hz, 4:4:4 color space), delivering four times the pixel density of 1080p and the smooth 60fps motion essential for live sports, gaming, and broadcast content. The system is fully HDCP 2.3 compliant, ensuring that 4K protected content from streaming services, 4K Blu-ray players, and cable/satellite providers displays correctly on every connected screen.
HDTV Supply, Inc. is a certified HDBaseT.Org Approved Adopter of HDBaseT™ products, guaranteeing interoperability and compliance with the global HDBaseT standard for long-distance AV signal distribution.
Key Features
The WolfPack 8x8 chassis is engineered with the reliability and flexibility required for permanent commercial AV installations. The following features distinguish it from fixed-port consumer and prosumer matrix switches.
True 4K@60Hz Performance
Supports 3840×2160 at 60 frames per second with 4:4:4 color space — four times sharper than 1080p and essential for live sports, gaming, and broadcast content.
Modular Hot-Pluggable Cards
Slide-in 4-port input and output cards allow quick field replacement without system downtime. Mix HDMI and HDBaseT cards in the same chassis for maximum flexibility.
HDBaseT Extension over CAT6
Optional HDBaseT cards extend 4K@60Hz signals up to 110 feet — or 1080p up to 220 feet — over standard CAT6 cable, eliminating costly long HDMI cable runs.
HDCP 2.3 & HDMI 2.0 Compliant
Full compliance with the latest content protection standard ensures 4K protected content from Netflix, Amazon, 4K Blu-ray, and cable/satellite displays without authentication errors.
Advanced EDID Management
Intelligent EDID handling ensures each source always receives the correct display capability data, preventing resolution mismatches, black screens, and audio dropouts when switching.
40 Customizable Preset Scenes
Save and recall up to 40 custom routing configurations with a single button press — ideal for venues that switch between regular programming, events, and presentations.
18 Control Methods
Control via iOS/Android app, Web GUI, RS232 serial, LAN/IP, and front-panel buttons. Optional certified drivers for Crestron, RTI, Elan, and 2-way Control4 are available.
Dual Redundant Power Supplies
Two independent 110V–240V AC power supplies provide automatic failover, ensuring uninterrupted operation in mission-critical environments like broadcast and hospitality.
Closed Caption Pass-Through
Full CC data pass-through ensures ADA compliance and accessibility for public venues including restaurants, bars, airports, and healthcare facilities.
Optional 7" Color Touch Screen
An optional touch screen panel provides intuitive on-site control without requiring a separate control system — ideal for sports bars and smaller venues.
Optional Sports Bar Control
Dedicated sports bar control integration lets staff manage all TVs and sources from a single iPad interface — no expensive control pads required.
