HDMI ARC Audio Extractor 4K@60Hz with Optical & 3.5mm Output - Compact

In this review of the HDMI ARC Audio Extractor 4K@60Hz from Arvitek, the bottom line is simple: this tiny converter is for anyone who needs to pull clean, high-resolution audio from a TV or HDMI source to an external sound system without replacing existing components. Its single biggest advantage is flexibility - it can operate as an ARC device to return TV audio to an amp or as a one-way HDMI audio extractor delivering optical S/PDIF and 3.5mm outputs while passing 4K video. The unit is compact and straightforward, making it a practical, no-frills solution for small home theater setups.

Key Features

• HDMI ARC support: Allows compatible TVs to send audio back to an external amplifier or receiver so you can use better speakers instead of the TV's internal speakers.
• Two audio outputs: Provides both optical S/PDIF and a 3.5mm AUX output so you can connect a soundbar, amplifier or powered speakers without needing RCA outputs.
• 4K@60Hz pass-through: Supports 4Kx2K at 60Hz and common resolutions including 1080p and 720p to keep picture quality intact while extracting audio.
• Multiple audio modes: Offers Pass, 2.0CH and 5.1CH settings so the extractor can output stereo or multichannel audio formats depending on your source and downstream device.
• Compact footprint: The unit measures about 2.3 x 2.3 x 1 in, which makes it easy to tuck behind equipment or near TV inputs without taking much space.

Who It's For

This product is best for homeowners or renters who want to route TV audio to an external amplifier or receiver using ARC, or for users who need to extract audio from a single HDMI source (such as a Blu-Ray player or TV box) while still outputting HDMI video to a display. It is helpful for small living rooms, bedrooms, or offices where a compact, simple converter is preferred.

It is not the right choice for systems requiring eARC support, RCA analog outputs, or multiple simultaneous HDMI inputs. Audiophiles needing advanced audio passthrough features or those with equipment that depends on eARC metadata should look for a more fully featured processor.

Pros & Cons

Pros

• Small and unobtrusive, making installation behind TVs or in AV cabinets straightforward.
• Supports 4K@60Hz video pass-through so there is no compromise in picture quality when extracting audio.
• Optical S/PDIF supports multichannel formats such as Dolby Digital and DTS-HD for surround-capable systems.
• Simple setup with either ARC return or HDMI input extractor operation for versatile use.

Cons

• Does not support eARC, so it cannot pass higher-bandwidth audio formats that require eARC.
• No RCA analog outputs are provided, limiting connection options for older receivers.

Frequently Asked Questions

Can I use my TV as an HDMI input with this device?
The TV cannot be used as an HDMI input in extractor mode; ARC mode requires both the TV and amplifier to support ARC.

Does this unit support eARC or high-resolution audio formats?
No, the device does not support eARC; optical output supports common multichannel formats like Dolby Digital and DTS-HD but not eARC-only formats.

Is a power adapter included?
A Type-C power cable is included, but a 5V power adapter is not supplied and must be provided separately.
