How to use two RØDECaster Series units into a Windows computer

  • Updated

If you need more analogue inputs than a single RØDECaster can provide, you can connect two RØDECaster Series units to the same Windows computer. This allows you to record up to eight analogue microphone inputs simultaneously in multitrack mode.

This setup is ideal for recording larger podcasts, live performances or any production requiring additional microphone inputs.

Please note: Windows cannot natively combine multiple USB audio interfaces. You'll need to use an ASIO driver such as ASIO4ALL to aggregate both RØDECaster units into a single audio device.

Compatible Products

This process works with any combination of RØDECaster Series devices, including:

  • RØDECaster Pro
  • RØDECaster Pro II
  • RØDECaster Duo

The example below uses REAPER with a RØDECaster Pro and RØDECaster Pro II.

Before You Begin

  1. Download and install ASIO4ALL.
  2. Connect both RØDECaster units to your computer via USB.
  3. Set both devices to Multitrack USB mode.

Configure Your DAW

  1. Open your DAW's Audio Preferences.
  2. Select ASIO4ALL v2 as the audio driver.
  3. Open the ASIO Configuration window.

ASIO4ALL driver selection

Enable Both RØDCaster Units

Within the ASIO4ALL configuration:

  • Enable both RØDECaster devices.
  • Disable any other active audio inputs or outputs using the power button icon.

Enable both RØDCaster devices in ASIO4ALL

Configure the Input Range

Close the ASIO4ALL window and configure your DAW's available input channels:

  • First Input: Pro Multichannel 1
  • Last Input: Pro II Main Multichannel 16 (Input 30)

This makes every multitrack input from both RØDECaster units available within your DAW.

Configure multichannel input range

Start Recording

  1. Close the Preferences window.
  2. Create a new audio track.
  3. Select the desired input for each track.

You'll now see every available multitrack input from both connected RØDECaster units.

Tip: Once configured, you can assign each microphone input to its own track, allowing you to edit and mix every channel independently after recording.
