RGB-to-HDMI Audio Add-On

The new RGBtoHDMI Audio Add-On for our RGBtoHDMI adapters allows the audio signal from the Amiga 500 or Amiga 2000 to be output through the adapter via the HDMI cable.

The small circuit board must be soldered to the adapter, and the solder pads for Left – G (Ground) – Right must be connected to the corresponding RCA jacks.
In the Amiga 500, this can be done very easily internally; for the Amiga 2000, we recommend connecting it to the jacks from the outside via an external cable, as shown in our retail kits.

Technically, the add-on works by tapping into the analog audio signal from the output (RCA jacks) and integrating it into the HDMI stream via an analog-to-digital converter. For this to work, the HDMI adapters also need new firmware!

Soldering skills and an adjustable soldering iron are required for installation. Caution: Do not solder at too high a temperature, as the add-on board is only 0.8 mm thick and excessive heat can very easily damage the AD converter. On the Amiga 500, the RGB-to-HDMI adapter must be raised slightly using a 48-pin adapter socket; otherwise, the add-on board will rest on top of the CIA, causing a short circuit.

Upon request, we can also install the add-on on RGBtoHDMI adapters purchased from us previously! To do so, please send us the adapter, including the SD card, properly packaged after purchase. Please note: We do *not* repair broken pins on the adapter!

The RGB-to-HDMI adapter was developed by @LinuxJedi Andrew Hutchings based on designs by “IanSB,” “c0pperdragon,” and “hoglet67.” Many thanks also to Daniel Jameson @drdpj @danielj (Bluesky) for the RGB2HDMI Audio Add-on. We’re happy to offer a little support for this outstanding project.
