De-embedder audio HDMI 4K analog 7.1 optical 5.1 - CYP AU-11SA-4K22

The CYP AU-11SA-4K22 is a 4K HDMI audio de-embedder that takes stereo or multi-channel audio from an HDMI source and makes it available through 7.1 analogue outputs, a 5.1 optical output and an HDMI bypass output. It handles LPCM 7.1, Dolby TrueHD, Dolby Digital Plus, Dolby Atmos and DTS-HD Master Audio, with sampling rates up to 192 kHz.

The unit processes 4K video at 60 Hz with 4:4:4 sampling, supports HDMI 2.0, HDCP 2.2 and DVI, and incorporates an HDMI repeater to keep the signal stable. Resolution support reaches 4K × 2K at 60 Hz YUV 4:4:4. The optical output carries LPCM, Dolby Digital and DTS up to 5.1, while the HDMI bypass path retains support for Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio. The analogue outputs handle LPCM 2.0, 5.1 and 7.1, and HDMI high-bit-rate HBR audio is supported.

The converter allows amplifiers and multi-channel analogue audio systems without the HDMI interface to be connected. It supports UHD 4K 60 content together with high-resolution audio formats, provides a 5.1 optical output for older soundbars and AV receivers, and keeps the original video on the HDMI bypass output without degradation. The integrated HDMI repeater helps preserve connection stability.

Applications include home-theatre installations with analogue multi-channel amplifiers, professional AV systems requiring 7.1 audio extraction from HDMI sources, conference rooms and corporate environments with advanced audio/video routing, soundbar or AV receiver integration through the 5.1 optical output, and setups that need multi-channel audio separated from 4K video. The manufacturer’s technical areas include video, audio, power, field firmware update through USB and enclosure.
