- Connect Audio Output:
- For RCA input devices (e.g., older stereo, soundbar): Connect an RCA L/R cable (not included) from the "AUDIO OUT" RCA ports on the DA25 to the corresponding L/R inputs on your audio device.
- For 3.5mm AUX input devices (e.g., headphones, portable speakers): Connect a 3.5mm stereo audio cable (not included) from the "AUDIO OUT" 3.5mm jack on the DA25 to your audio device.
- Connect Power: Connect the provided USB power cable to the "DC 5V" micro USB port on the DA25. Plug the USB-A end into a standard USB wall charger (not included) or an available USB-A port on your TV/media equipment.
- Power On: The PWR LED will illuminate, indicating the device is powered. The ARC LED will light up once an active ARC/eARC signal is detected from your TV.
- TV Audio Settings: Access your TV's audio settings and ensure the audio output format is set to PCM/LPCM 2.0 channel. This device does not support Dolby, DTS, or other multi-channel audio formats.

Image: A diagram illustrating the connection flow: a TV with ARC output connects via HDMI to the OREI DA25. The DA25 then outputs audio simultaneously to headphones via a 3.5mm jack and to RCA speakers via L/R RCA cables. A note emphasizes setting TV audio output to Stereo or 2.0ch PCM.
5. Operating Instructions
The OREI DA25 is designed for plug-and-play operation. Once all connections are made and your TV's audio output is configured to PCM/LPCM 2.0, the converter will automatically extract and convert the audio. There are no additional controls on the device for volume or CEC functionality.
- Ensure your TV's HDMI ARC/eARC feature is enabled.
- Verify that your TV's audio output format is set to PCM/LPCM 2.0.
- Adjust volume directly on your connected audio system or headphones.
