USB-C Stereo Audio Adapter

The RCA USBC-AC2 adds separate 3.5 mm headphone and microphone ports to any USB-C equipped PC, Mac, Android phone or tablet. It works as an external sound card for gaming headsets, conference calls or casual listening. No driver installation is required on supported operating systems.

Plug-and-play thermal profile

The adapter draws power directly from the host USB-C port and runs without active cooling. In normal use it stays cool to the touch and produces no audible noise. Power consumption is negligible compared to the host device's battery or supply.

Dual 3.5 mm ports included

The single USB-C plug breaks out to one TRS headphone jack and one TRS microphone jack, letting you connect both audio output and input simultaneously. The package contains only the adapter itself; no cables, carrying case or configuration software are supplied.

Questions about this item

How do I plug the RCA USBC-AC2 into my USB-C laptop and connect a headset with separate 3.5 mm plugs?

Insert the USB-C male connector into the host port, then push the headphone plug into the jack marked for headphones and the microphone plug into the jack marked for microphone; no driver installation is required.

What part of the adapter is most likely to wear out first with daily plugging and unplugging?

The two 3.5 mm TRS sockets and the USB-C male plug are the mechanical contact points that endure repeated insertion cycles.

What is the maximum sample rate the internal DAC supports during continuous playback?

The adapter operates at a fixed 48 KHz sample rate for stereo audio.
