Product Research


4x1 HDMI Switcher: The Metra CS-HDM4X1ASW4 lets you connect up to 4 HDMI source devices to a single HDMI input on your AV receiver or TV, while sending digital or analog audio out to another audio playback device.

HDMI 2.0 (18Gbps): Metra's CS-HDM4X1ASW4 HDMI switcher supports HDMI 2.0 and HDCP 2.2, along with Ultra HD 4K and HDR video. The switcher is capable of receiving and transmitting video bandwidths up to 18Gbps. It also supports up to 7.1ch audio, including Dolby TrueHD and DTS-HD.

  • 4K Resolution: The CS-5X1HDMSPL4 is compatible with ultra-HD video resolutions up to 4k @ 60Hz with support of YCBR 4:4:4 color subsampling. It is also compatible with high definition video up to 1080p @ 60Hz; including 3D video. In addition, the switcher offers support for 1080i, 720p, and 480i video resolutions.
  • HDR Formats: The Metra 4X1 HDMI switcher supports all the major HDR formats - including HDR 10, Dolby Vision, and HLG (Hybrid-Log Gamma).
  • HDCP 2.2 Compliant: HDCP 2.2 is supported by all of the HDMI splitter's inputs & outputs; HDCP is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with 4K Blu-ray players and 4K Satellite/Cable providers.
  • Up to 7.1ch Audio: Metra's CS-HDM4X1ASW4 HDMI switcher supports up to LPCM 7.1ch, Dolby TrueHD, and DTS-HD Master Audio.

Digital & Analog Outputs: The audio embedded in HDMI can be extracted via optical (toslink) digital, coaxial (RCA) digital, or stereo analog minijack (3.5mm); allowing you to send audio from and HDMI input source device out to another audio playback device lacking HDMI connectivity. The stereo analog minijack output can even be used to connect a set of headphones. The optical and coaxial digital outputs support 2ch or 5.1ch audio, while the stereo analog output supports 2ch only. Audio will be output simultaneously from the optical, coaxial, and stereo minijack outputs if you have them all connected at once

ARC (Audio Return Channel): If you have the switcher's HDMI output connected directly to your TV's HDMI ARC input and one of the switcher's HDMI inputs connected to the HDMI ARC output on your AV receiver, you can have the audio from the TV returned to your AV receiver.

Controls: The following controls are found on the front-panel of the HDMI switcher and on the included remote control - Source Select (1-4), ARC, and Audio Output Select (2ch or 5.1ch). The included IR remote also offers Power On/Off, Mute, and Pass (pass-through). The CS-HDM4X1ASW4's IR receiver is located on the front-panel.

Power Requirements: Metra's CS-HDM4X1ASW4 HDMI switcher operates off of standard household current using the supplied AC power adapter (Input: 100-240V ~ 50/60Hz, 0.2A; Output: 5.0V/1A).

Mounting Options: The CS-HDM4X1ASW4 HDMI switcher can simply be placed horizontally on a flat-surface, such as on top of a shelf of a piece of AV furniture. It also comes with two mounting brackets to mount in vertically on a wall or piece of AV furniture (mounting screws not supplied).

Customer Q&A

3 questions already asked

Which HDMI port out of the 4 supports ARC?
[ Amit  Nov 18, 2021 ]
1 answer
I think all inputs support ARC. There is an "ARC" button on the front.
[ CHARLES  Nov 19, 2021 ]
Does the audio output support surround 5.1 and 7.1? I have purchased boxes which separated sound in the past and the sound was very distorted. This for an amplifier input which works fine with Apple TV optical sound output.

I am using the Metra to select the HDMI inputs to my Yamaha Receiver. I have a 5.1 configuration and it works perfectly. I do not have a 7.1 set up. I am using a Harmony 950 to control all of my components including the Metra. It is import to have the Harmony 950 set to leave the Metra On.
[ Mark  Dec 11, 2020 ]
Anyone have any issues with this and the PS4 Pro running HDR?
[ Chris  May 27, 2020 ]
2 answers
We do not store information to know if one of our customers has tried it but given its specifications, we do expect it will work with the PS4 Pro and any HDR it can send out
[ Paul  Jun 20, 2020 ]  Staff
Just got mine a couple of weeks ago. Set up was easy and operation has been a breeze. Allowed me to extend my third HDMI port into 4 ports. Small, functional......a very satisfactory solution!
