Frequently Asked Questions - AT-HD520 Atlona

What is the Atlona AT-HD520 used for?

The AT-HD520 is an HDMI audio extractor/converter that extracts digital audio from an HDMI signal and outputs it via optical (Toslink) or analog stereo (RCA) simultaneously, while passing through the video to an HDMI display.

Does the AT-HD520 support 4K video?

No, the AT-HD520 supports video resolutions up to 1080p (60 Hz). It does not support 4K. For 4K applications, consider a different model.

How do I connect the AT-HD520?

Connect an HDMI source (e.g., Blu-ray player, gaming console) to the HDMI Input port. Connect an HDMI display to the HDMI Output for video pass-through. Connect your audio system (e.g., soundbar) to either the Optical Output or Analog L/R Output. Then power the unit via the micro-USB port.

How do I switch between audio output types?

The AT-HD520 outputs audio via both optical and analog simultaneously when the source provides a compatible signal. There is a built-in audio mode switch: set it to 2CH for downmixed stereo output, or BYPASS for pass-through of multichannel bitstream audio (e.g., Dolby Digital, DTS) to the optical output.

Does the AT-HD520 require external power?

Yes, the AT-HD520 requires 5V DC power via the included micro-USB cable and power adapter. It does not draw power from HDMI.

What audio formats are supported?

The AT-HD520 supports PCM 2.0, Dolby Digital, DTS 5.1, Dolby TrueHD, and DTS-HD Master Audio. In bypass mode, it can output bitstream formats via optical. In 2CH mode, it downmixes multichannel audio to stereo PCM for the analog outputs.

Can I use the AT-HD520 with a PlayStation or Xbox?

Yes, the AT-HD520 works with game consoles that output HDMI audio. Connect the console to the HDMI input, and the display to the HDMI output. If your console uses HDMI 2.0 for 4K video, note that the AT-HD520 only supports up to 1080p.

How do I reset the AT-HD520 to factory defaults?

The AT-HD520 does not have a factory reset feature. To resolve issues, try unplugging the power for 10 seconds, then reconnect. Ensure all cables are securely connected.

Why is there no sound from the analog output?

Check that the audio mode switch is set to 2CH for analog output. Also confirm that your source is outputting audio and that the analog cables are properly connected to an active input on your audio system. If using optical, ensure the receiving device is set to optical input.

What cables are included with the AT-HD520?

The package includes a 5V/1A power adapter and a micro-USB power cable. HDMI, optical, and analog cables are not included and must be purchased separately.
