Behringer PS400｜Switchable 12V / 48V Phantom Power Supply

A compact phantom power supply that gives condenser microphones stable power right away

The Behringer PS400 is a phantom power supply from Behringer, offering switchable 12V / 48V phantom power. With a low-noise signal path and all-metal chassis, it is ideal for creating a stable, clean connection environment for various condenser microphones that require external power.

Compared with the traditional approach of relying on a mixer or audio interface’s built-in phantom power, the Behringer PS400 uses an independent power architecture so devices without phantom power can still be used with condenser microphones. Compared with similar entry-level power boxes, its advantages are 12V / 48V switching, compact size, and low-noise transmission, making it especially suitable for mobile recording and simplified signal-chain setups.

Who should buy the Behringer PS400?

User Recommendation Analysis (Click to expand)

▼

Who Should Buy

New creators who already have a condenser microphone but whose mixer or recording device has no phantom power
People who need to record on the go or set up a temporary audio system and want a compact device to quickly add microphone power
Small studio users who want to keep their existing gear and make condenser microphones work properly via an external solution

Who Should NOT Buy

Users who already have recording interfaces or mixers with multiple built-in stable phantom power supplies and do not need an extra power box
Users who only use dynamic microphones and have never needed phantom power for their system

Behringer PS400 Core Technology and Features

12V / 48V phantom power switching：Supports two-level phantom power output, allowing switching according to different microphone or device requirements for greater system compatibility and flexibility.
Independent power architecture：Operates via an external power supply, so it does not rely on built-in phantom power from a mixer, preamp, or audio interface, allowing older gear to work with condenser microphones.
Low-noise signal path：The official design emphasizes low noise, helping maintain the cleanliness and stability of the original audio signal while supplying microphone power.
Simple Mic Input / Mic Thru connection concept：Connect the microphone to Mic Input, then send the signal from Mic Thru to a mixer or other downstream device; the wiring logic is intuitive and suitable for quick deployment.
All-metal chassis：The enclosure uses an all-metal structure, offering better durability and interference resistance for daily carrying, desktop use, and live mobile setups.
Compact and portable：Small size and minimal configuration make it easy to fit into a recording bag, live-streaming kit, or small PA toolbox as a temporary power solution.

12V / 48V Phantom Power Switching

Outputs either 12V or 48V phantom power to match different microphones and real-world recording system needs.
Offers greater flexibility for condenser microphones that require standard 48V power, as well as some devices that can accept lower voltage.

Low-noise microphone signal transmission design

The PS400 is not just a power box; it also uses a low-noise design for the signal path, reducing the risk of introducing extra noise.
It can help maintain more stable signal quality for voice recording, live streaming, simple vocal recording, and conference systems.

All-metal chassis and mobile-use convenience

The all-metal enclosure is more suitable than a typical plastic shell for long-term carrying and repeated plugging/unplugging, making it safer for live use.
The compact size makes it easy to integrate into desktop recording, small PA, mobile live streaming, and presentation audio pickup systems without adding much cabling burden.

Behringer PS400 FAQ

Q：Can the Behringer PS400 let a mixer without phantom power use a condenser microphone?

▼

A：Yes. The PS400 can power the condenser microphone first, then send the signal to downstream equipment.

Q：What is the difference between 12V and 48V on the PS400?

▼

A：The difference is the supply voltage. 48V is more common, while 12V provides compatibility with specific devices.

Q：Is the PS400 suitable for podcast recording or live streaming beginners?

▼

A：Yes. If you already have a condenser microphone but your equipment has no phantom power, the PS400 is very practical.

Q：What is the difference between the PS400 and an audio interface with built-in phantom power?

▼

A：They are different. The PS400 only provides power; an audio interface also includes conversion, monitoring, and connectivity functions.

Q：Can the PS400 be used with a dynamic microphone?

▼

A：It can be connected in the system, but the PS400’s main value is providing the power required by condenser microphones.
