USB 1 and USB Chat

USB 1 is the primary USB audio interface. Use this to connect your RØDECaster Pro II to your computer for recording and exporting audio (USB 1 facilitates multitrack recording and is also linked to the microSD card reader). USB 1 will appear as ‘RØDECaster Pro II Main’ in your list of audio devices.

USB 1 also features a virtual channel hosted on the same interface called USB 1 Chat. This is a completely separate audio channel that can be allocated to its own fader, just like any other audio input. Use this for connecting remote callers or online guests via a computer. USB 1 Chat will appear as ‘RØDECaster Pro II Chat’ in your list of audio devices.

Note: USB 1/RØDECaster Pro II Main does not have mix-minus applied to the channel. If you use this for making calls, your guest may hear an echo. USB 1 Chat has mix-minus applied permanently, hence why we recommend using it for making calls.


USB 2 can be thought of as a secondary USB interface. Use this to connect smartphones or tablets to your RØDECaster Pro II. Mix-minus is optional on this channel, making it ideal for making remote calls, and it is also MFi-compliant, meaning it will interact seamlessly with iOS devices. It can also be used for connecting another computer (USB 2 will appear as ‘RØDECaster Pro II Secondary’ in your list of audio devices). Having a second USB interface means the audio can be routed to a separate channel, giving you more control over levels and a cleaner signal for mixing in post-production. You can also connect USB 2 to the same computer as USB 1, giving you three USB audio devices on a single computer.

The Bluetooth connection on the RØDECaster Pro II is useful for connecting remote callers wirelessly. It is easy to set up and use and can connect to smartphones, tablets, or computers. This connection features mix-minus for echo-free communication, plus wide-band speech, ensuring very high-quality audio.

Pro Tip

If your Bluetooth channel is not receiving audio, ensure that the level on your device is turned up.

Pro Tip

You can also activate Back Channel mode by pressing the ‘Listen’ and ‘Mute’ buttons for the channels you want to be able to communicate. However, using the SMART pads is much quicker and easier.
