USB Microphone Kit

This guide walks through how to connect and configure the USB microphones.

Connecting the microphone

1. Place Microphone in Magnetic Base
The volume dial should face the same direction as the gold circle on the base.
2. Connect the USB-C Cable and Headphones to the Microphone
Connect the microphone(s) to your computer using the provided USB hub.
Connect the headphones to the microphone(s).
This allows you to hear the input of that microphone.
3. Setup your recording environment
  • Position the front of the microphone to be 6 inches from the speaker's mouth. Place the microphone on top of books or another stable surface if needed. 

  • Listen with the headphones provided while recording. If you can't hear through the headphones, click the volume knob on the microphone to enable playback.



Creating an Aggregate Device


1. Click on your desktop to activate Finder.  Navigate to the top toolbar and click Go>Utilities>Audio MIDI Setup.


2. Click the + button and select "Create Aggregate Device."  A new aggregate device will appear in the left pane. 


3. Rename to Rode USB mics. 


4. Select the newly named USB Mics Aggregate Device and check all Rode NT-USB Audio devices listed in the right pane.  Check Drift Correction. 


1. Install Voicemeeter, a free app we will use to create the aggregate device, and then restart your computer. 

2. Go to Control Panel > Hardware & Sound > Sound > Manage Audio Devices > Recording, here you may adjust the microphone levels and its recording settings. We recommend 24 bit 48000 Hz. 

3. Open Voicemeeter and select your output as your computer's speakers and configure the first two channels' inputs to the two Rode Mics. Make sure to select the mics that have the WDM label. 

This app will act as your aggregate device that you may select when opening an audio recording application such as Audacity
