What else you need to use it

Revelator io24
An XLR microphone and an XLR cable for each input you use
Headphones with a 1/4-inch plug, or a 3.5 mm adapter
A USB-A port on your computer

Worked out from PreSonus’s own specifications and box contents for this model. The setup builder checks the same parts against your computer and the rest of your gear.

You need

  • An XLR microphone and an XLR cable for each input you use. Its microphone inputs: 2 XLR microphone preamps with 48 V phantom power; Instrument input. USB versus XLR
  • Headphones with a 1/4-inch plug, or a 3.5 mm adapter. Its headphone socket is 1/4-inch.

Check first

  • A USB-A port on your computer. The cable in the box is USB-C to USB-A. If your computer only has USB-C ports, use a USB-C to USB-C cable instead.

When this model makes sense

  • Connect your microphones to the computer through one interface; count how many voices you need at once before choosing.
  • Listen on its headphone outputs, and give a remote guest a separate mix so they don’t hear themselves.
  • Record each channel you need into OBS or your recording app, then play each one back to check it went where you meant.

The Interface versus mixer guide weighs it against the other ways to fill the same role.

Check these conditions first

Not yet confirmed from PreSonus’s documents: operating systems. The builder treats it as unknown, never as a yes.

For an interface, count the microphone inputs and headphone outputs you need. Loopback sends your computer’s sound back in so you can record or stream it; mix-minus sends a guest everything except their own voice. They solve different problems, so check for the one you need.

What is included, and what may be missing

  • Revelator io24 USB audio interface
  • 1 m USB-C to USB-A cable
  • Quick Start Guide
  • PreSonus Health, Safety and Compliance Guide
  • Warranty/registration card

Both cable ends and the data rating matter more than the plug shape: streaming cables and ports explains how to match them.

The diagram shows a simple USB setup. Find where the PreSonus Revelator io24 goes, then follow each input back to what feeds it and each output on to where it goes. HDMI and XLR gear needs a capture card or audio interface between it and your computer; it doesn’t plug straight in the way this USB example does.

The setup builder turns this into a connection list for your own computer and gear, and the pre-stream checklist covers the rehearsal once it is wired.
