Aodafy HDMI ARC Audio Extractor Pro — 192KHz DAC, ARC to Optical/Coaxial/Analog (H103-ARC Pro)

Overview

The Aodafy H103-ARC Pro is a versatile HDMI ARC audio extractor and DAC designed to simplify how you connect your TV to a broader sound system. It supports three input modes—HDMI ARC, optical (SPDIF), and coaxial—and can route sound to multiple outputs at once when you enable ARC on your TV. The built-in 192kHz DAC helps translate digital signals into rich analog stereo, making it easier to feed legacy speakers, amplifiers, or multi-room setups without swapping cables.

Designed with real‑world use in mind, this adapter offers flexible routing, straightforward setup, and compatibility with a wide range of home theater gear. It’s a practical upgrade for households that want to keep TV audio options open while expanding listening possibilities across different audio paths.

Key capabilities

• ARC, optical SPDIF, and coaxial inputs with a simple switch to select your current source.
• ARC mode distributes TV audio to Optical, Coaxial, RCA L/R, and 3.5mm outputs simultaneously.
• DAC mode converts Optical or Coaxial digital audio to analog stereo for your speakers or receiver.
• 192kHz high sampling rate for clear, detailed sound reproduction.
• In ARC mode, you can adjust volume using your TV remote for RCA and 3.5mm outputs.

How ARC mode works

In ARC mode, set the device to ARC and connect it to your TV’s HDMI ARC port. Your TV’s audio signal then flows through to the Optical, Coaxial, RCA L/R, and 3.5mm outputs, enabling synchronized sound across multiple devices without extra steps.

Digital to analog converter mode

To use as a DAC, switch the input to Optical or Coaxial and connect to your TV or streaming device’s Optical SPDIF/Coaxial output. The unit converts digital signals into analog stereo, which can be fed into powered speakers or an analog‑input receiver for improved compatibility with older gear.

TV setup and important notes

• Ensure your TV has an HDMI port labeled ARC, enable CEC, and set the audio output to HDMI (ARC) with PCM/LPCM or Source format.
• In ARC mode, your TV remote can control volume for RCA L/R and 3.5mm outputs. Coaxial or Optical paths do not support remote volume control.
• Note: Some soundbars with HDMI‑only inputs may not be compatible with ARC to this adapter.

Why this can matter in daily life

This compact accessory helps you maximize the audio potential of your TV setup. By offering flexible routing and easy control, it supports varied listening scenarios—watching movies, streaming shows, gaming, or enjoying music via different speakers—without committing to a single connection path. It’s a practical, non‑restrictive upgrade for many living rooms and home theaters.
