4×1 HDMI switch with audio extraction

The Vszerda unit routes four HDMI sources to one display while pulling audio out through optical, coaxial and 3.5 mm analogue jacks. It accepts 4K signals up to 60 Hz with 18 Gbps bandwidth and supports HDR10. The switch is aimed at owners of sound bars or AV receivers that lack enough HDMI inputs.

Passive operation with no fan noise

The device draws power from the HDMI connections and adds no active cooling, so it runs silently in a cabinet. HDMI 2.0b cables up to three metres work at 4K 60 Hz, while five metres are possible at 4K 30 Hz. Maximum per-channel bandwidth is 600 MHz and the switch complies with HDCP 2.2.

Replaces manual cable swapping

It upgrades setups that currently unplug devices to change sources or that use a switch without audio breakout. The jump is worth it when you need simultaneous optical and analogue feeds for separate zones, or when your display has only one HDMI port but you run four 4K sources.

Questions about this item

How do I connect the four HDMI sources and get sound through the optical or coaxial outputs, and which step is often missed?

Connect each source to one of the four HDMI inputs, run an HDMI cable from the output to the display, then link the Toslink or coaxial port to your sound system; the step often missed is enabling ARC on the TV and setting the extractor to the correct EDID mode so audio passes through.

What maintenance or replacement will the IR remote need over time?

The IR remote uses a standard button cell that will need replacing when the range drops; no other user-serviceable parts exist inside the switch.

At what resolution and refresh limit does the 18 Gbps bandwidth cap appear first during sustained 4K use?

The 18 Gbps ceiling is reached at 4K 60 Hz with 8-bit 4:4:4 colour; dropping to 4K 30 Hz or using 4:2:2 subsampling keeps you within the limit.
