BZBGEAR 4x1 HDMI 2.1 8K UHD Switcher with Audio De-Embedding (8K60/4K120Hz 4:4:4, VRR/FVA/ALLM)

The BZBGEAR 4x1 HDMI 2.1 switcher combines four HDMI sources into a single 8K-capable output while providing audio de-embedding for external sound systems. It is HDCP 2.3 compliant to ensure compatibility with current copy-protection requirements. Video enhancement features include Variable Refresh Rate (VRR), Frame-Velocity Awareness (FVA), Auto Low Latency Mode (ALLM), Quick Media Switching (QMS), Quick Frame Transport (QFT), and Source-Based Tone Mapping (SBTM). HDR and audio are passed through intact with support for HDR, HDR10, HDR10+, Dolby Vision, and HLG. Compatible HDMI audio formats include LPCM 7.1CH, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS. CEC control lets the TV send commands to source devices and enables the TV to control volume on any connected eARC sound system. Advanced EDID management optimizes handshake and signal compatibility across different devices. The unit handles high bandwidths—48Gbps FRL and 18Gbps TMDS—and conforms to HDMI 2.1 bandwidth requirements, supporting up to 8K@60Hz 4:2:0 12bit, 8K@30Hz 4:4:4 12bit, and 4K@120Hz 4:4:4 12bit resolutions. Firmware can be updated via the USB Type-C port for future improvements. The switcher routes four HDMI inputs to a single HDMI output and supports HDMI input plus TV eARC audio de-embedding to SPDIF and L/R outputs. It is suitable for sending audio to SONOS ARC & Beam or any eARC-compatible soundbar.
