8K HDMI Audio Extractor OREI BK-104A 4-Output 8K@60Hz Optical & Analog

Description

Product Overview

The OREI BK-104A is a purpose‑built HDMI audio extractor designed for users who demand pristine sound from ultra‑high‑definition video sources. Supporting 8K resolution at 60Hz, this device captures the full audio bandwidth of modern content and redirects it to either optical (TOSLINK) or analog (RCA) outputs, ensuring compatibility with a wide range of legacy and high‑fidelity speaker systems. The extractor maintains the original video stream untouched, passing it through to your display without any loss of quality. Constructed from a robust aluminum chassis, the BK‑104A offers a sleek, low‑profile footprint—measuring just 8.5 x 3.75 x 1 inches—making it easy to integrate into tight entertainment centers or portable setups. Dual‑voltage capability, with a US plug and an included international adapter, allows seamless operation worldwide. The unit is engineered for plug‑and‑play simplicity: connect your HDMI source, attach the desired audio cable, and power the device. No drivers or firmware updates are required, and the extractor automatically detects the audio format, delivering clear, lag‑free sound for movies, games, and streaming content.

Usage

Designed for home theater enthusiasts, gamers, and professional presenters, the BK‑104A fits naturally into a variety of environments. In a living‑room setup, connect a 4K/8K streaming device or gaming console to the extractor, then route the audio to a high‑end soundbar or a traditional stereo system via the optical output. This configuration provides immersive surround sound without the need for HDMI‑ARC‑compatible receivers. For office or classroom presentations, the analog RCA outputs can feed a PA system or conference speaker, allowing clear voice playback from laptops or media players that output HDMI video. The extractor’s compact size makes it ideal for travel‑friendly AV rigs, where space is at a premium. Its dual‑voltage power supply means you can take it abroad for hotel room entertainment or on‑the‑go gaming sessions without worrying about plug compatibility. Whether you are watching a blockbuster, streaming a live sports event, or delivering a corporate demo, the BK‑104A ensures the audio experience matches the visual fidelity of your source.

FAQ

Does the extractor support Dolby Atmos or DTS:X audio formats?

The BK‑104A extracts the core audio channels and outputs them via optical or analog connections. While it does not pass through object‑based formats like Dolby Atmos or DTS:X directly, it delivers the underlying channel‑based audio, which can still provide an immersive experience when paired with compatible speakers.

Can I use the extractor with a TV that has HDMI‑ARC?

Yes, you can place the extractor between your source device and the TV. The HDMI‑ARC function on the TV will continue to work for audio return, but the extractor will handle the audio routing to external speakers, allowing you to bypass the TV’s internal speakers if desired.

What is the maximum cable length for the optical output?

For optimal signal integrity, we recommend using optical cables up to 10 meters (33 feet). Longer runs may require active optical cables to maintain audio quality.

Is a firmware update required to support 8K video?

No firmware update is necessary. The BK‑104A is built to handle 8K video streams out of the box, and it automatically detects and processes the incoming signal without user intervention.

What warranty does OREI provide for this product?

OREI offers a one‑year limited warranty covering manufacturing defects. The warranty includes free technical support and, if needed, repair or replacement of the unit.
