4-Port 4K HDMI Switch with Audio Extraction

This Vszerda unit connects four HDMI sources to a single display while extracting audio through HDMI, optical Toslink and 3.5 mm analogue outputs. It suits home-cinema and gaming setups that need to route multiple 4K devices to one screen and separate sound to an amplifier, soundbar or powered speakers.

HDMI 2.0b bandwidth and audio format limits

The switch handles 18.5 Gbps throughput, supporting 4K resolution at 60 Hz with HDR 10, HDCP 2.2 and 36-bit Deep Colour. HDMI and optical outputs carry up to 7.1-channel Dolby Digital, Atmos, DTS:X and PCM formats, while the optical port is limited to 5.1-channel Dolby Digital or DTS and PCM 2.0, and the 3.5 mm jack delivers stereo PCM only.

Check your sources, display

Verify that each source device can output 4K at 60 Hz over HDMI 2.0b and that your display accepts the same signal with HDCP 2.2. Confirm your amplifier or soundbar has an optical Toslink input for 5.1 surround or a 3.5 mm analogue input for stereo, because the switch cannot down-mix multi-channel audio to formats the optical or analogue ports do not support.

Questions about this item

How do I choose between the HDMI, optical and 3.5 mm outputs for my sound system?

Use the HDMI output for full 7.1-channel Atmos or TrueHD, the optical port for Dolby Digital or DTS 5.1 and PCM 2.0, and the 3.5 mm jack for simple stereo PCM 2.0.

What does the 18.5 Gbps bandwidth mean when I connect a 4K 60 Hz source?

It carries 4K at 60 Hz with HDR 10, RGB 8:8:8 and deep colour up to 36-bit without compression.

How does the HDMI 2.0b interface limit the audio formats I can send through ARC?

ARC over HDMI 2.0b passes Dolby Digital and DTS 5.1 plus PCM 2.0; lossless 7.1 formats need the main HDMI output.
