Overview

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.

Key features

HDCP 2.2 and HDCP 1.4 compliant.
Supports HDMI resolution up to 4K2K@50/60Hz (4:4:4), per HDMI 2.0b.
Passes the full 18Gbps of video bandwidth to all four HDMI outputs.
Extracts digital and analog audio from the HDMI source.
Output bypass and 4K to 1080P downscaler, selected by a panel dial switch; the downscale switch is global to all four outputs.
EDID set to COPY or AUTO mode via a panel dial switch. In COPY mode the unit copies OUT 1's EDID to all outputs, cascading to OUT 2, then OUT 3, then OUT 4 if no capable EDID is detected. In AUTO mode it compares OUT 1 through OUT 4 and outputs the best shared resolution.
Analog audio output: PCM 2.0 on a 3.5mm stereo mini-jack.
Optical S/PDIF output supports LPCM 2.0/2.1CH, Dolby 5.1, Dolby TrueHD, Dolby DD+, DTS 5.1, DTS-ES 6, DTS-HDMA 5.1 and DTS HD-HRA 5.1.
Metal enclosure with an external 5V/1A power supply.

What is the maximum video bandwidth of the SP-HDMI1X4A-18G?

It handles 18Gbps, supporting HDMI 2.0b signals up to 4K2K at 50/60Hz with 4:4:4 color.

Which HDCP versions does the SP-HDMI1X4A-18G support?

It is compliant with both HDCP 2.2 and HDCP 1.4.

Does the SP-HDMI1X4A-18G need a control system or network to run?

No. It is configured entirely by two front-panel dial switches, one for EDID mode and one for 4K-to-1080p scaling, with no external control connection required.

Can the SP-HDMI1X4A-18G feed displays and a separate audio system at the same time?

Yes. A typical setup drives up to four UHD TVs from the HDMI outputs while the optical output feeds an amplifier and the analog L/R output feeds a pair of 2.0 speakers, all from the single source.

What connects to each port on the SP-HDMI1X4A-18G?

The HDMI source, such as a Blu-ray/DVD player or games console, connects to the IN port, and your four displays connect to OUT 1 through OUT 4. The optical S/PDIF output and the 3.5mm analog L/R output each carry the audio extracted from the HDMI input.

How is the SP-HDMI1X4A-18G powered?

Connect the supplied 5V/1A DC adapter to the DC 5V jack and plug the adapter into an AC outlet rated 100-240V, 50/60Hz. The POWER LED lights when the unit has power.

The SP-HDMI1X4A-18G shows no signs of life. What should I check?

Check the POWER LED on the front panel; it lights only when the unit has power. If it is dark, confirm the 5V/1A DC adapter is connected to the DC 5V jack and plugged into a live AC outlet.

No picture reaches one of the displays on the SP-HDMI1X4A-18G. How do I isolate it?

Look at that port's HDMI OUTPUT LED, which lights when the OUT port is connected by cable to an active display; if it is off, check the cable and the display at that end. Then confirm the HDMI INPUT LED is lit, which shows the source is connected and active on the IN port.

My install mixes a 4K TV with an older 1080p projector on the same source — will this drive both?

Yes, with one switch. Set the downscale switch ON and all four outputs get 1080p, so the projector and the TV both take the feed; set it OFF and all four get the native signal. It cannot run one output at 4K and another at 1080p at the same time.

How do I get sound to an amplifier or DSP that has no HDMI input?

The unit de-embeds audio to two outputs at once: optical S/PDIF (carrying LPCM, Dolby 5.1, Dolby TrueHD/DD+, and DTS 5.1 formats) for a surround processor, and analog L/R on a 3.5mm jack (PCM 2.0) for a stereo amp or ceiling-audio input. No separate de-embedder needed.
