Overview
Bridges the gap between HDMI 2.1 eARC displays and legacy AV receivers by de-embedding ARC/eARC audio from any 8K-capable TV or HDMI source and routing it via HDMI directly to the amplifier — no AVR replacement required. Fully compliant with HDMI 2.1 and HDCP 2.3, supporting data rates up to 48Gbps FRL with zero video and audio latency.
Designed for CEDIA integrators specifying retrofit and new-build installations, the AUD-AMP-8K handles video resolutions up to 8K@60Hz and 4K@120Hz with full HDR pass-through (HDR10, HDR10+, Dolby Vision, HLG) and HDMI 2.1 protocols including VRR, ALLM, QMS, QFT, and SBTM. Eight DIP-switch EDID modes, CEC volume control, and a USB-C firmware update port ensure long-term serviceability in the field.

There is no audio from the amplifier - what should I check?
Verify the eARC button is set to the correct mode, confirm ARC/eARC is enabled in the TV audio settings if using eARC return, check the amplifier's HDMI input is connected to Amp AUDIO OUT, and try toggling the eARC button to reset the CEC handshake.
The IN or OUT LED is not lighting - what does that mean?
The green IN LED confirms a detected input signal at Source IN, the OUT LED confirms the TV(eARC) OUT port is connected to a display, and the Amp LED confirms the Amp AUDIO OUT port is connected to an amplifier; an unlit LED points to a loose or missing HDMI connection at that port.
Why choose the AUD-AMP-8K over replacing an AV receiver?
It de-embeds ARC/eARC audio from an 8K-capable TV or HDMI source and routes it directly to an existing amplifier at full 48Gbps HDMI 2.1 video bandwidth, letting integrators add eARC compatibility to legacy AVRs without a full receiver swap.
How does the AUD-AMP-8K fit into an eARC-to-AVR retrofit?
It sits between an 8K-capable source and an eARC TV: Source IN accepts the HDMI source, TV(eARC) OUT feeds the display, and Amp AUDIO OUT sends de-embedded ARC/eARC audio directly to a legacy AV receiver, adding eARC audio without replacing the AVR.
The eARC LED is flashing - what does that indicate?
A flashing eARC LED means ARC/eARC is enabled but CEC communication or the ARC channel is not established; check that Premium High Speed HDMI cables rated for 48Gbps are used on all connections and confirm CEC is enabled on both the TV and source.
How does CEC control work on this adapter?
The unit supports CEC control and CEC volume control, passing commands from the TV to the source and amplifier; the eARC button enables or disables the eARC function, and the eARC LED indicates CEC/ARC handshake status.
What HDMI and HDCP versions does the AUD-AMP-8K support?
The AUD-AMP-8K is HDMI 2.1 compliant with HDCP 2.3 support, handling video bandwidth up to 48Gbps FRL and 18Gbps TMDS.
What HDR formats and HDMI 2.1 protocols are supported?
HDR10, HDR10+, Dolby Vision, and HLG pass through, along with HDMI 2.1 protocols VRR, ALLM, QMS, QFT, and SBTM.
What HDMI cable lengths are recommended for each resolution?
For 8K@60Hz use Ultra HDMI 2.1 cable at 2m/6.6ft to 3m/10ft; for 4K@60Hz standard Premium HDMI up to 5m/16ft; for 4K@30Hz up to 10m/33ft; for 1080p up to 15m/49ft.
There is no video on the display - what should I check?
Confirm Ultra HDMI 2.1 cables are used for 8K@60Hz runs (2-3m max), use standard Premium HDMI up to 5m for 4K@60Hz, check that the EDID DIP switch setting matches the display capability, and try DIP mode [111] to copy the TV's EDID automatically.
