HDMI audio extractor with eARC and 8K support
With the Marmitek Connect AE34, you can play sound from your TV—whether it's from apps, a built-in decoder or a connected HDMI source—simultaneously through a soundbar and a separate home cinema system or amplifier. Ideal if you want to control multiple audio systems or zones without hassle.

This device supports the latest video standards such as Ultra HD 8K@60Hz, 4K@120Hz and HDR10+. So you can enjoy the very best picture and sound, without compromise. Thanks to support for Deep Colour and full 4:4:4 chroma, colour gradients are razor-sharp.

The Connect AE34 extracts the audio signal from the HDMI source (audio de-embedding) and sends it via a HDMI, digital (Toslink) or analogue 3.5 mm output to an amplifier, receiver or active speaker system. The video signal continues on to your TV or projector without interruption.

Unique: use your TV’s eARC function, even if your audio equipment doesn’t support it. That way you get the most out of your setup—without needing to replace your entire system.

With the built-in EDID switch, you can easily set the desired audio format. Whether you use stereo, 5.1 or 7.1—you always have control over the signal.

The Marmitek Connect AE34 is the perfect solution for anyone looking to intelligently split and distribute audio without any loss of quality.

Use the optical (TOSLINK), HDMI or 3.5 mm analogue outputs to feed your soundbar, amplifier or active speakers.

The video signal continues to the display uninterrupted while audio is extracted for external systems.

Recommendations

For best results, use high-quality HDMI 2.1 cables to maintain full bandwidth and enable features like 4K@120Hz or 8K@60Hz. If you rely on eARC from the TV, ensure the TV’s audio output settings are configured to pass-through or eARC and adjust EDID to match your audio equipment capabilities.
