Question 1

Four HDMI inputs and two HDMI outputs, routed independently. HDMI 2.0, HDCP 2.2/1.4 and DVI 1.0 compliant at 18Gbps.

Question 2

What is the maximum video resolution?

Accepted Answer

Up to 4K@60Hz YCbCr 4:4:4, with all HDMI 3D formats, and Dolby Vision, HDR10+ and HLG pass-through.

Question 3

What audio can I take off it separately from the displays?

Accepted Answer

Optical Toslink S/PDIF carrying PCM 2.0, Dolby Digital, Dolby Digital Plus and DTS, plus an analog L/R output at PCM 2.0.

Question 4

How is it controlled?

Accepted Answer

By the front panel or the supplied IR remote.

Question 5

How is it mounted and powered?

Accepted Answer

Two mounting ears are supplied for rack or shelf fixing. Power is a 12V/1A locking adapter, 3.8W maximum. The chassis is 9.88in x 0.79in x 4.13in and weighs 1.37 lbs.

Question 6

What is in the box?

Accepted Answer

The 4x2 matrix switcher, a 12V/1A locking power adapter, two mounting ears, an IR remote and the user manual.

Question 7

The analog L/R output has gone silent.

Accepted Answer

The L/R output mutes while ARC is active. That is by design, not a fault.

Question 8

A display shows nothing on one input.

Accepted Answer

Check that the source is within HDCP 2.2 or 1.4 and inside the 18Gbps budget: 4K@60Hz 4:4:4 at 12-bit exceeds what the link can carry to every output at once.

Question 9

Can it feed two displays and a separate audio system at the same time?

Accepted Answer

Yes. The two HDMI outputs run independently and the optical and analog audio outputs are extracted at the same time.

Question 10

Does it handle HDR?

Accepted Answer

Yes, Dolby Vision, HDR10+ and HLG pass through, with 8-bit, 10-bit and 12-bit colour depth.
