MuxLab IMU-500437 - 4x1 4K/60 HDMI Selector with Audio Extraction and ARC Support
The MuxLab IMU-500437 is a professional signal switching solution designed for demanding audiovisual environments that require flexibility, high performance, and superior audio management. This 4x1 HDMI switch allows you to connect up to four HDMI video sources (such as Blu-ray players, game consoles, computers, or set-top boxes) to a single 4K display or projector, simplifying cabling infrastructure without sacrificing image quality.
Unlike standard switches, this model stands out for its audio extraction capability. It allows you to separate the audio signal from the HDMI input and send it independently to external sound systems, soundbars, or amplifiers that lack an HDMI input, ensuring seamless integration between modern video equipment and dedicated audio systems. Its robust metal construction and compatibility with the latest content protection standards make it a reliable centerpiece for any AV installation.
With full support for UHD 4K resolutions at 60Hz and 4:4:4 color sampling, the device ensures transparent, lossless video transmission. It also incorporates advanced features such as Audio Return Channel (ARC) and intelligent EDID management, offering three selectable audio modes (Passthrough, 2.0, and 5.1) to suit your sound system's capabilities.

Frequently Asked Questions
-
Does the selector support HDR?
Yes, being compatible with HDMI 2.0 and supporting a bandwidth of 18 Gbps, it is capable of transmitting signals with high dynamic range (HDR) as long as the source and display support it.
-
Can I use the optical and analog outputs at the same time?
Generally, the device will output audio through both outputs simultaneously if the input format is compatible (PCM 2.0). For multichannel formats such as Dolby 5.1 or DTS, only the optical output will work, as the analog output (RCA) cannot decode surround sound.
-
Does it require an external power supply?
Yes, the unit includes its own 5V DC power supply to ensure a stable signal and proper functionality of active audio extraction.
-
What audio formats does the optical output support?
The Toslink output supports LPCM 2.0, Dolby Digital 5.1 and DTS 5.1.
