The WolfPack 4K60 8x8 HDMI Matrix Switcher (part number HDTV-WP-8X8-4K60-ARC) routes any of 8 HDMI sources to any of 8 HDMI displays at 4K/60Hz 4:4:4 with full 18Gbps bandwidth. Each output has its own independent 4K → 1080p downscaler, so legacy 1080p displays keep working on the same matrix as your 4K screens. Audio is de-embedded to 8 coaxial and 8 analog L/R outputs, and HDMI ARC returns TV audio back down the same cable to your soundbar or AVR.
What is the WolfPack 8x8 HDMI Matrix (HDTV-WP-8X8-4K60-ARC)? It is an 18Gbps, 1U rack-mounted HDMI 2.0b matrix switcher with 8 inputs and 8 outputs. It supports 4K60 4:4:4, HDCP 2.2, HDR10, HDR10+, Dolby Vision and HLG, per-output scaling, ARC, CEC and smart EDID management. Control it from the front panel, the included IR remote, RS-232, LAN/Telnet or the built-in Web GUI.
Why Buyers Choose This 8x8 Matrix
True 18Gbps, No Compromise
HDMI 2.0b with full 18Gbps bandwidth on every port. 4K60 at 4:4:4 chroma, 12-bit color depth, and HDR10, HDR10+, Dolby Vision and HLG all pass through untouched.
Independent Scaler Per Output
Set any output to Bypass, 4K → 1080p, or Auto. Mix 4K TVs and 1080p displays on the same system without downgrading the whole matrix.
Audio De-Embedded 8 Ways
Every output has a coax RCA and a 3.5mm analog L/R jack. Feed zone amps, distributed audio or a mixing board without an external extractor.
ARC Brings TV Audio Back
Enable ARC per output and the TV's internal apps send audio back through the matrix to the coax output feeding your AVR or soundbar.
CEC Control Built In
Power sources and displays on or off, navigate menus, and control volume and transport over CEC from the Web GUI or RS-232, with no extra IR wiring.
Five Ways to Control It
Front panel buttons with OLED readout, IR remote, RS-232, TCP/IP with Telnet, and a browser-based Web GUI with 8 savable presets.

Which WolfPack 8x8 Matrix Is Right For You?
HDTV Supply builds several 8-input matrix switchers. They differ in resolution ceiling, output count and how audio is handled. Use this to pick the right one before you order.
| Model | Max Resolution | Outputs | Audio De-Embed | Best For |
|---|---|---|---|---|
| HDTV-WP-8X8-4K60-ARC (this product) |
4K60 4:4:4, 18Gbps | 8 | Coax + analog L/R on all 8 | Sports bars, home theater and conference rooms running current 4K sources where you also need separate audio feeds and ARC. |
| WolfPack 4K30 8x8 | 4K30 | 8 | Varies by model | Budget installs where sources top out at 4K30 or 1080p and the extra bandwidth would go unused. |
| WolfPack 8K60 8x8 HDMI 2.1 | 8K60 4:2:0 / 8K30 4:4:4 | 8 | Optical + balanced analog | Future-proofing for 8K sources, or installs that need seamless switching with no screen blanking. |
| WolfPack Fixed 8x9 | Varies by model | 9 | Varies by model | When you need one more display than an 8x8 provides, such as a ninth screen for a lobby or back office. |
| WolfPack Fixed 16x16 | Varies by model | 16 | Varies by model | Larger venues running more than 9 displays, or installs expected to grow past 8 TVs. |

Frequently Asked Questions
What is the part number for this 8x8 HDMI matrix?
The HDTV Supply part number is HDTV-WP-8X8-4K60-ARC. Use this number when ordering, requesting a quote, or opening a support ticket so we can pull the correct firmware and documentation for your unit.
Does this 8x8 HDMI matrix support 4K 60Hz 4:4:4?
Yes. On the HDTV Supply WolfPack HDTV-WP-8X8-4K60-ARC, all eight inputs and all eight outputs support 4K2K@60Hz at full 4:4:4 chroma with 18Gbps bandwidth, HDMI 2.0b and HDCP 2.2. No chroma subsampling is required.
Can I mix 4K and 1080p displays on the same matrix?
Yes. This is one of the main reasons integrators choose this WolfPack matrix. Each output has its own independent scaler that can be set to Bypass, 4K → 1080p, or Auto. Set the outputs feeding 1080p displays to downscale while your 4K outputs stay in bypass at native resolution.
Does it support HDR and Dolby Vision?
Yes. The WolfPack HDTV-WP-8X8-4K60-ARC passes HDR10, HDR10+, Dolby Vision and HLG through untouched when the output is set to bypass mode and the source, cable and display all support the format.
How do I get audio out to an amplifier or soundbar?
Every one of the eight outputs on this WolfPack matrix has a coaxial RCA audio output and a 3.5mm analog L/R output. Coax carries LPCM 2.0, Dolby Digital / Digital Plus and DTS 5.1. The analog L/R jacks carry PCM 2.0. No external audio extractor is needed.
What does the ARC feature do on this matrix?
ARC returns audio from a smart TV's built-in apps back down the HDMI cable to the matrix, where it is output on that output's coax port to your AVR or soundbar. Turn ARC on per output in the Web GUI or with s hdmi y arc 1! over RS-232.
What is the default IP address and login?
On the HDTV Supply WolfPack HDTV-WP-8X8-4K60-ARC, the default IP address is 192.168.1.100 with subnet 255.255.255.0, TCP/IP port 8000 and Telnet port 23. The admin login is username Admin and password admin. A limited User login is available with username User and password user. You can read the current IP from the front panel OLED or by sending r ipconfig! over RS-232.
What are the RS-232 serial settings?
115200 baud, 8 data bits, 1 stop bit, no parity. Every ASCII command ends with an exclamation point. The baud rate can be changed to 57600, 38400, 19200, 9600 or 4800 from the front panel, the Web GUI System page, or with s baud rate 9600!.
Can I save routing presets?
Yes. The matrix stores 8 named presets. Save the current routing with s save preset 1! and recall it later with s recall preset 1!, or manage presets from the Video page of the Web GUI.
Will this work with Control4, Crestron, Savant or Home Assistant?
Yes. The WolfPack HDTV-WP-8X8-4K60-ARC accepts standard ASCII commands over RS-232 at 115200 baud, over TCP/IP on port 8000, and over Telnet on port 23. HDTV Supply also publishes third-party drivers for Control4, Elan and RTI. Any control system, automation platform or custom script that can send ASCII strings can drive it.
How far will HDMI run from this matrix?
Using Premium High Speed HDMI cable, expect 16 ft / 5 M at 4K60, 32 ft / 10 M at 4K30, and 50 ft / 15 M at 1080p60 on both the input and output side. For longer runs, add HDBaseT or fiber HDMI extenders on the affected outputs.
What is the rack size and power draw?
The WolfPack HDTV-WP-8X8-4K60-ARC is a 1U rack-mount chassis measuring 440mm wide by 200mm deep by 44.5mm high, weighing 2.8 kg. Two mounting ears are included. It draws 43W from the supplied 12V/5A external power adapter.
What if my display shows no picture or the wrong resolution?
This is almost always EDID, and it is the single most common support call HDTV Supply gets on any matrix switcher. Set the affected input to a defined EDID that matches your lowest common display, such as mode 1 for 1080p Stereo 2.0 or mode 16 for 4K2K60_444 Stereo 2.0, using s edid in 1 from 16! or the Input page of the Web GUI. You can also copy the EDID directly from a connected display with modes 24 through 31.
Specifications, default network settings and the RS-232 command set on this page were verified by HDTV Supply against the manufacturer documentation on August 6, 2026. Firmware updates may add commands; contact support at 833-WOLFPACK (833-965-3722) if your unit behaves differently.
