Question 4

How does CEC control work on this adapter?

Accepted Answer

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.

Question 5

What are the dimensions and weight of the AUD-AMP-8K?

Accepted Answer

3.74 in x 2.68 in x 0.71 in (95 x 68 x 18mm), 0.39 lbs (0.18kg), housed in a black metal enclosure.

Question 6

What is included in the box?

Accepted Answer

The package contains the AUD-AMP-8K adapter, a 5V/2A multinational power supply (CE/FCC/UL certified), and a user manual.

Question 7

There is no audio from the amplifier - what should I check?

Accepted Answer

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.

Question 8

The eARC LED is flashing - what does that indicate?

Accepted Answer

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.

Question 9

How does the AUD-AMP-8K fit into an eARC-to-AVR retrofit?

Accepted Answer

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.

Question 10

Why choose the AUD-AMP-8K over replacing an AV receiver?

Accepted Answer

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.
