PROZOR 192KHz HDMI ARC to Optical Audio Adapter Instruction Manual

1. Introduction

This manual provides detailed instructions for the installation, operation, and troubleshooting of your PROZOR 192KHz HDMI ARC to Optical Audio Adapter. This device is designed to extract audio from your TV's HDMI Audio Return Channel (ARC) port and convert it into either Optical (Toslink/SPDIF) or Coaxial digital audio outputs. This allows you to connect your TV's audio to external sound systems such as soundbars, amplifiers, or receivers that do not have HDMI ARC inputs.

Important Notes:

This converter is designed for TV HDMI ARC ports only, not for standard HDMI or HDMI eARC ports.
It supports uncompressed 2-channel LPCM or PCM digital audio signals. It does not decode 5.1 channel audio formats like Dolby Digital or DTS.
The signal transmission is one-way; it cannot be reversed.
Volume control must be managed directly on your connected audio device (amplifier, soundbar), not via the TV remote.

Optical (Toslink) Output: Connects to your audio device's optical input.
Coaxial Output: Connects to your audio device's coaxial input.
USB Type-C Power Input: Connects to a 5V USB power source (e.g., TV USB port).

4. Setup Instructions

Follow these steps to correctly set up your PROZOR ARC Audio Extractor:

4.1. Connecting the Adapter

Identify TV ARC Port: Locate the HDMI port on your TV labeled "ARC" or "HDMI ARC". It is crucial to use this specific port. Do not use standard HDMI or HDMI eARC ports.

Image 4.1: This diagram illustrates how to correctly identify and connect the adapter to your TV's HDMI ARC port. It highlights the ARC-labeled port and shows incorrect connections to standard HDMI or eARC ports.
Connect HDMI ARC Cable: Plug the integrated HDMI ARC cable from the PROZOR adapter into your TV's HDMI ARC port.
Connect Audio Output: Connect either the Optical (Toslink) cable or a Coaxial cable (not included) from the PROZOR adapter's output to the corresponding input on your soundbar, amplifier, or receiver.

Connect Power: Connect the supplied USB Type-C power cable to the adapter's DC 5V input. Plug the other end (USB-A) into an available USB port on your TV or a 5V USB wall adapter (not included). The adapter requires 5V 1A power.

4.2. TV Audio Settings Configuration

For optimal performance and compatibility, adjust your TV's audio settings as follows:

Enable CEC: Ensure that Consumer Electronics Control (CEC) is enabled on your TV. This feature is often named differently by various TV manufacturers (e.g., Anynet+ for Samsung, Bravia Sync for Sony, SimpLink for LG).
Set Audio Output to HDMI ARC: Navigate to your TV's audio settings and select "HDMI ARC" or "Audio Out (HDMI ARC)" as the primary audio output.
Set Audio Format to PCM or LPCM: This converter supports uncompressed 2-channel PCM/LPCM audio. Access your TV's expert audio settings and set the digital audio output format to "PCM" or "LPCM". Avoid "Dolby Digital," "DTS," or other compressed multi-channel formats, as the converter will not decode them.

5. Operation

Once the setup is complete, your PROZOR ARC Audio Extractor will automatically convert the audio from your TV's ARC port to the selected digital output (Optical or Coaxial).

Audio Output: The adapter provides a stable, electromagnetic-noise-free transmission of uncompressed 2-channel PCM audio.
Volume Control: The TV remote will not control the volume of the connected audio device. Please adjust the volume directly on your soundbar, amplifier, or receiver.
High-Resolution Audio: The adapter supports sampling rates at 32, 44.1, 48, 96, and 192kHz, delivering high-resolution audio.

6. Troubleshooting

If you encounter issues, please refer to the following common problems and solutions:

Problem	Possible Cause / Solution
No audio output.	Ensure the adapter is connected to the TV's HDMI ARC port, not a standard HDMI or eARC port. Verify that the TV's audio output is set to HDMI ARC. Confirm the TV's digital audio format is set to PCM or LPCM. Check all cable connections (HDMI, Optical/Coaxial, USB power) are secure. Ensure the audio device (soundbar/amplifier) is powered on and set to the correct input (Optical or Coaxial). Try a different USB power source for the adapter.
Audio is distorted or intermittent.	Verify the TV's digital audio format is set to PCM or LPCM. Compressed formats (Dolby, DTS) are not supported for decoding. Check for loose cable connections. Ensure the USB power supply is stable (5V 1A).
TV remote does not control volume.	This is expected behavior. Volume must be adjusted directly on your connected soundbar, amplifier, or receiver. The adapter does not support CEC volume control passthrough to the connected audio device.
Adapter does not work with soundbar ARC port.	The adapter is designed to extract audio from a TV's ARC port and output to an audio device's Optical or Coaxial input. It is not compatible with soundbar ARC ports for input.
