The OREI HDMI 18Gbps Audio Extractor with HDCP 2.2 is a versatile device designed to enhance your audio-visual experience by separating audio signals from an HDMI source. This allows you to route the audio to a dedicated sound system while the video continues to your display. It's an ideal solution for home theater setups, gaming environments, or any scenario where you need more control over your audio output.
At its core, the extractor takes an HDMI input and provides both an HDMI output for video and separate audio outputs. This means you can connect your HDMI source, such as a Blu-ray player, gaming console (like a PS4), or a streaming device, to the extractor. The video signal, including high-resolution formats, is then passed through to your TV or projector via the HDMI output. Simultaneously, the audio signal is extracted and made available through either a digital optical (S/PDIF) output or an analog stereo L/R audio output. This flexibility allows you to connect to a wide range of audio receivers, soundbars, or active speakers, providing a more immersive and high-fidelity sound experience than what might be available directly from your display.
One of the key usage features of this device is its support for high-resolution video and audio formats. It can handle video resolutions up to 4K2K at 50/60Hz with YUV444 chroma subsampling, ensuring that your high-definition content is displayed with pristine clarity. For audio, it supports HDMI high-resolution digital audio formats bypass, including LPCM 2CH, Dolby TrueHD, Dolby Digital Plus, Dolby Atmos, and DTS-HD Master Audio. This comprehensive audio support means you can enjoy the latest surround sound technologies, bringing cinematic audio quality to your living room. The audio sampling rate can go up to 192 kHz, further contributing to a rich and detailed sound.
The device also boasts support for 10-bit HDR (High Dynamic Range) pass-through. This is crucial for modern displays and content, as HDR significantly enhances contrast and color accuracy, resulting in more vibrant and lifelike images. By supporting HDR pass-through, the extractor ensures that the visual quality of your content is not compromised when routing audio separately. Furthermore, it is compliant with HDCP 2.2, which is essential for playing protected content from many modern sources. It also supports CEC bypass, allowing for seamless control of connected devices through a single remote, if your setup supports it.
The operation of the extractor is straightforward, featuring clearly labeled ports and indicators. On the front panel, you'll find the DC 5V power input, where you connect the provided 5V/1A power adapter. A Power LED indicates when the system is receiving power. An important control is the "TV / Bit Stream / 2CH" switch, which allows you to select the desired audio format. This flexibility is vital for compatibility with different audio systems. For instance, you might choose "2CH" for stereo output to a soundbar, or "Bit Stream" to send a compressed multi-channel audio stream (like Dolby Digital or DTS) to an AV receiver for decoding. The HDMI In port is where you connect your source device, and a Link LED illuminates when an HDMI input signal is detected, providing a quick visual confirmation of connection status.
On the rear panel, the HDMI Out port connects to your display device, such as a TV or projector, carrying the video and any unextracted audio. The L/R Audio Out is a 3.5mm stereo mini-jack, perfect for connecting to analog audio inputs on an amplifier, soundbar, or active speakers. The Optical Out (S/PDIF) port provides a digital audio signal, which is ideal for connecting to AV receivers or soundbars that support optical input, offering higher fidelity and multi-channel audio capabilities.
For maintenance, the device is designed for reliability and ease of use. It comes with a metal enclosure, which provides durability and helps dissipate heat, contributing to a longer lifespan. The compact dimensions and lightweight design make it easy to integrate into any existing setup without taking up much space. While the manual doesn't detail specific cleaning instructions, general care for electronic devices, such as keeping it free from dust and ensuring proper ventilation, would apply. The robust design and support for current HDMI and audio standards mean it's built to last and remain relevant as your home entertainment system evolves.
In summary, the OREI HDMI 18Gbps Audio Extractor is a practical and powerful tool for anyone looking to optimize their audio setup. Its ability to extract high-quality audio from HDMI sources, coupled with support for advanced video formats like 4K HDR and comprehensive audio codecs, makes it an indispensable component for a modern home theater. The user-friendly interface and robust construction further enhance its appeal, ensuring a reliable and enjoyable experience.
