4K60 1×4 HDMI Splitter with Optical + Analog Audio Extraction

Feeds one 4K60 4:4:4 HDMI source to four displays while handing a clean audio feed off to a legacy amp or DSP — without a separate de-embedder in the rack. Housed in a black metal enclosure and powered by an external 5V/1A supply, this 1×4 distribution amplifier passes the full 18Gbps of HDMI 2.0b to all four outputs with HDCP 2.2 and 1.4 compliance. It is the right choice for boardrooms, signage clusters, lecture halls and media rooms where deterministic EDID, an onboard downscaler and audio breakout matter more than 8K bandwidth or KVM.Dial-selectable EDID COPY and AUTO modes give integrators a deterministic handshake across mixed displays instead of the lowest-common-denominator guess of a basic splitter, and a single global 4K to 1080P downscale switch drives older 1080p screens and projectors from the same 4K source. Audio de-embeds to two destinations at once: optical S/PDIF carrying LPCM, Dolby 5.1, Dolby TrueHD, DD+ and DTS bitstream for a surround processor, and analog L/R (PCM 2.0) on a 3.5mm jack for a stereo amp or ceiling-audio zone. That combination — full 18Gbps distribution, deterministic EDID, onboard downscaling and dual audio de-embed in one metal chassis — is what sets it apart from disposable prosumer splitters.
