VigilLink VLHA-H21DWM HDMI 2.1 eARC Audio Adapter for AV Receivers

The VLHA-H21DWM extracts audio from HDMI sources or ARC and eARC televisions and hands it to an AV receiver over HDMI. When a display upgrade outruns the receiver in the rack, this adapter keeps the existing amplifier in the signal path.

It handles 48Gbps FRL and 18Gbps TMDS bandwidth under HDCP 2.3, supporting 8K@60Hz 4:2:0 12-bit and 4K@120Hz, with VRR, ALLM, QMS, QFT, and SBTM as specified in HDMI 2.1. EDID management and cable equalization are built in.
