Product Research


1x2 HDMI Splitter: The Simplified MFG SP12S is an HDMI 2.0b splitter with pass-through, downscaling, EDID management, and audio breakout. Its supports resolutions up to 4K/60Hz (4:4:4) and HDCP 2.2 or 1.4. The SP12S can be used to split a single HDMI audio/video input into two HDMI audio/video outputs, whether they are identical or not. 

Note: The SP12S HDMI splitter does not support ARC (Audio Return Channel).

HDMI 2.0b (18Gbps): The SP12S features one HDMI 2.0b input and two HDMI 2.0b outputs with support for 18Gbps video bandwidth, 4K ultra-HD resolution, HDR (High Dynamic Range), and HDCP 2.2.

  • 4K Resolution: Supports video formats up to 4k @ 24/30Hz (RGB / YcbCR 4:4:4 / YCBCR 4:2:2); and up to 4k @ 50/60Hz (YCBCR 4:4:4). It also offers support for 720p @ 50/60Hz and 1080p @ 50/60Hz.
  • HDR (High Dynamic Range): Supported HDR formats included HDR10, HDR10+, and Dolby Vision.
  • HDCP 2.2: HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players and 4K Satellite/Cable providers. Its also backward compatible with HDCP 1.4.

Video Pass-Through or Down-scaling: An HDMI video signal can be split into two identical signals or can be down-scaled. 4K, 1080p, and 720p video signals can be set to pass-through without scaling. A 4K video signal can be down-scaled to 1080p for older TVs and displays.

Note: The SP12S HDMI splitter does not offer upscaling.

EDID Management: Each HDMI output can be set to 1080p or to the EDID setting. EDID (Extended Display Identification Data) can be copied or mixed (Auto).

  • Auto Mode: The Auto mode compares the EDID settings of the two connected TVs or displays, and then selects the lowest resolution of the two. Your HDMI input source device will transmit the same video to both outputs at the same resolution.
  • Copy Mode: The Copy mode copies the EDID settings from the TV or display connected to the HDMI 1 output to the HDMI 2 output. Your HDMI input source device will transmit the same video signal to both outputs at the same resolution of the HDMI 1 output.

Audio Outputs: The Simplified MFG SP12S offers HDMI audio pass-through, as well as an analog and digital audio breakout.

  • HDMI Audio Pass-Through: The SP12S will pass-through an HDMI audio signal with a sampling rate up to 192kHz. Supported HDMI audio formats include LPCM (2/5.1/7.1ch), Dolby Digital, Dolby Digital+, Dolby TrueHD, Dolby Digital EX; as well as DTS, DTS-EX DTS 96/24, DTS-HD, and DT-HD Master Audio.
  • Analog & Digital Audio Breakout: In addition to HDMI audio pass-through, the SP12S has an optical (toslink) output and a 3.5mm analog minijack output for audio breakout. The optical (toslink) digital out will support PCM (2ch), Dolby Digital (5.1ch), and DTS (5.1ch); while the 3.5mm minijack output is only 2ch stereo.

AC Power Adapter: The included AC power adapter plugs into the SP12S HDMI splitter and into an AC wall outlet or surge protector.

Customer Q&A

1 question already asked

Will this allow me to run one hdmi from my 4k video source to my processor (which doesn't support 4k) for sound, and the other to my 4k projector? My video source is Xbox series x which has no optical and one hdmi. I currently have the hdmi from Xbox going to the processor, and an hdmi from processor to the 4k projector. Unfortunately the processor isn't 4k. So I'd have to feed directly from Xbox to the projector.

I use for video projector, should work for your application as you would have one hdmi cable from Xbox into this splitter, then you have two HDMI outputs that are always active, one goes to TV and one goes to Projector. I unplug my projector when not used. Hope this helps, and good luck.
