Recording Audio Straight from a Portable PA System [No Mixer]?
Recording high-quality audio directly from a PA system without a mixer can be challenging, but it is possible with the right setup and equipment. Whether you’re capturing live performances, public speeches, or outdoor events, knowing how to properly connect your recording device to the PA system ensures clear and balanced sound. In this guide, we’ll explore different methods for recording audio straight from a PA system, troubleshooting common issues, and optimizing sound quality.
Why Record Directly from a PA System?
Convenience and Simplicity
Using a PA system for audio recording eliminates the need for additional mixing gear, making the setup quicker and more portable. This is especially useful for:
- Solo performers or small bands who don’t carry a full studio setup
- Public speakers who need to document their presentations
- Event organizers capturing live sound for future reference
Cost-Effective Solution
Many PA systems have built-in outputs that allow direct recording, removing the need for expensive mixing consoles or audio interfaces.
Consistent Sound Quality
Recording from a PA system ensures that you capture the same processed audio being projected to the audience, often including EQ, effects, and compression.
How to Connect a Recording Device to a PA System
1. Use the PA System’s Line Out or Record Output
Most PA systems have a dedicated line-out, rec-out, or headphone out jack. You can connect this to your recording device using:
- 3.5mm TRS to TRS cable (for smartphones, laptops, or recorders)
- RCA to 3.5mm cable (for older PA systems)
- XLR to 3.5mm adapter (for professional audio recorders)
2. Connect Directly to the Speaker Output (With Caution)
If your PA system lacks a dedicated output, you can use a DI box (Direct Injection Box) to safely tap into the speaker output. Steps include:
- Connecting speaker output to the DI box
- Using the DI box’s balanced output to feed a recorder
- Ensuring proper gain adjustment to prevent distortion
3. Use a USB-Enabled PA System
Some modern PA systems offer USB recording, allowing direct connection to a computer for digital audio capture. Simply:
- Plug the PA system into a laptop via USB
- Use software like Audacity or GarageBand to record
- Adjust input levels for optimal clarity

Troubleshooting Common Issues When Recording from a PA System
Issue 1: Distorted or Clipped Audio

Issue 2: Background Noise and Hiss
- Solution: Use shielded cables and avoid unnecessary gain boosts.
Issue 3: Unbalanced Audio or Missing Channels
- Solution: Ensure you’re using a stereo or balanced connection where necessary.
Recording directly from a PA system without a mixer is possible and can deliver high-quality results with the right setup. By using the PA’s built-in outputs, USB features, or a DI box, you can capture clean audio for music, speeches, and events. Whether you choose the Bose S1 Pro, JBL EON One Compact, or another PA system, proper gain adjustment and cable selection are key to achieving the best recording quality.
