Before you begin

  1. Download and install UA Connect.
  2. Register your Volt in UA Connect and install any available firmware updates.
  3. Install UAD Console if your Volt model supports it, as listed below.

Windows

The Volt Driver is required on Windows to access all of Volt's input and output channels. Before configuring OBS, complete the following:

  1. Download and install UA Connect.
  2. Register your Volt in UA Connect, install the Volt Driver, and install any available firmware updates.
  3. Install UAD Console if your Volt model supports it, as listed below.

UAD Console Compatibility with Volt

UAD Console is compatible with Volt Gen 2, Volt Max, and Volt 876. It is not compatible with first-generation Volt models. Interfaces are grouped as follows:

  • UAD Console compatible: Volt 1 Gen 2, Volt 2 Gen 2, Volt 4 Gen 2, Volt 2 Max, Volt 4 Max, Volt 4P Max, Volt 876
  • Not UAD Console compatible: Volt 1, Volt 2, Volt 176, Volt 276, Volt 476, Volt 476P

Every model in both groups will follow the same OBS configuration steps described in this article. Only the monitoring and preamp control options differ.

Connect Volt to your computer

  1. Connect Volt to your computer using the included USB cable.
  2. Power on Volt if your model features a power switch.

Note: Connect Volt directly to a port on your computer whenever possible. If you must use a hub, use a powered USB hub to ensure the interface receives sufficient power.
