What is Audio Mixer?
An audio mixer (also called a mixing board or mixing console) is a device that combines multiple audio sources, adjusts their levels, and routes them to a recording device or output. For podcasters, mixers allow you to control multiple microphones, add sound effects, and adjust EQ in real-time during recording.
Podcast mixers come in two main types:
- Analog mixers: Traditional hardware with physical faders and knobs
- Digital mixers/podcast consoles: Include built-in effects, USB output, and often sound pads
| Mixer Type | Best For | Example |
|---|---|---|
| Basic USB Mixer | Solo/duo podcasts | Behringer Q802USB |
| Podcast Console | Live shows, sound effects | RODECaster Pro II |
| Digital Mixer | Multi-host studios | Zoom LiveTrak L-8 |
Key mixer features for podcasting include phantom power for condenser mics, headphone outputs for each host, and USB connectivity for direct computer recording.
Why It Matters
While many podcasters use simple audio interfaces, a dedicated mixer gives you hands-on control during recording. You can adjust levels on-the-fly, mute guests who aren't speaking, trigger sound effects and music, and monitor everything in real-time. This is especially valuable for live podcasts, interview shows, and productions with multiple hosts.
How to Use This in Dispatch
When setting up a podcast mixer, connect each microphone to its own channel and set initial gain levels during sound check. Use the channel faders for relative volume adjustments between hosts, and the master fader for overall output level. Monitor through headphones connected to the mixer to hear exactly what's being recorded.
