Extron DXP 42 HD 8K – 4x2 8K HDMI Matrix Switcher with Audio De-embedding

Product Overview

DXP 42 HD 8K, part number 60-1879-01. The Extron DXP 42 HD 8K is a 4x2 8K HDMI matrix switcher that routes any of four sources to either of two displays independently. It supports HDMI 2.1 at data rates to 40.1 Gbps, covering resolutions up to 8K/60 as well as ultra-wide and 5K formats, with VRR, HDR, Deep Color to 12-bit, 3D, and HD lossless audio. HDMI audio de-embedding lets program audio route to a DSP or sound system rather than display speakers. The switcher is HDCP 2.3 compliant across all inputs and outputs.

Product Description

Two-display rooms are now standard in mid-size and large conference spaces, and the two displays rarely want the same content at the same time. A matrix rather than a switcher is what makes independent routing possible: content on one screen, a camera feed or agenda on the other, changed without disturbing either.

The DXP 42 HD 8K provides four inputs and two outputs with independent routing. Signal handling covers HDMI 2.1 at up to 40.1 Gbps, supporting 7680x4320 at 60 Hz with 4:2:0 chroma and 10-bit color, 4:4:4 at 30 Hz, and 5120x2880 at 60 Hz with 4:4:4 and 12-bit for 5K layouts. High frame rate operation reaches 3840x2160 at 120 Hz.

Variable Refresh Rate support is unusual in a commercial matrix and matters in simulation, esports, and sports analysis rooms where frame pacing affects the work being done. HDR support and Deep Color to 12 bits per color cover the image quality side, while HD lossless audio formats pass through intact for rooms with capable sound systems.

Audio de-embedding is the practical integration feature. Rather than accepting display speaker audio or adding a separate de-embedder to the rack, the matrix extracts HDMI audio for routing into a DSP, amplifier, or ceiling speaker zone. Combined with HDCP 2.3 compliance across the signal path, that makes it straightforward to specify into a room where laptops carry protected content and audio has a designed path.

For single-display rooms with two sources, the smaller Extron SW2 HD 8K covers the same signal specification in a two-input switcher. At 8K and high frame rates, specify certified 48 Gbps HDMI cable such as the Extron HD 8K series throughout.

Frequently Asked Questions

What is the difference between a matrix and a switcher here?

A switcher sends one selected source to one output. This matrix routes any of the four inputs to either of the two outputs independently, so the two displays can show different content simultaneously and be changed without affecting each other.

Does it support Variable Refresh Rate?

Yes. VRR is supported alongside the other HDMI 2.1 features, which is relevant in simulation, esports, and sports analysis spaces where frame pacing affects the work.

Where does the de-embedded audio go?

The matrix extracts audio from the HDMI signal for routing into a DSP, amplifier, or ceiling speaker zone, so program audio uses the room's designed sound system rather than display speakers.

What HDMI cable should I specify?

At 8K and high frame rates, use certified 48 Gbps ultra high speed HDMI cable such as the Extron HD 8K series on all inputs and outputs. Standard high speed cable will not reliably carry 40.1 Gbps.

Is it HDCP compliant for corporate laptops?

Yes, HDCP 2.3 compliant across all inputs and outputs, which covers current protected content requirements from laptops and media sources.

What if I only need two sources and one display?

The Extron SW2 HD 8K is a two-input switcher with the same audio de-embedding capability and an even higher 48 Gbps data rate ceiling.

When does it ship?

Extron lists this model as shipping in September 2026. Contact Creation Networks for current lead time and to reserve project quantities.

What warranty applies?

Extron provides a manufacturer warranty, and Creation Networks coordinates warranty and RMA handling.
