## Summary description

Mozos PS400 is a power supply unit that provides phantom +48V and an additional +12V output for XLR microphones. Designed to feed professional condenser and other XLR microphone types that require external power, it supports microphone operation where in-board phantom power is unavailable. Useful for studio recording, live sound, podcasts and field recording setups needing reliable external power.

## Long description

Mozos PS400 Phantom +48V and +12V for XLR microphones is an external power supply designed to provide stable phantom voltage and an auxiliary +12V output for professional condenser and other XLR microphone types that require external powering. The unit supplies +48V phantom power for standard studio and live microphones, while the +12V output can be used for microphones or devices that need lower voltage. Mozos PS400 is intended for situations where in-board phantom power is not available or when separate, dedicated power improves consistency of microphone performance.
Advantages
The Mozos PS400 delivers reliable and consistent +48V phantom power suitable for condenser microphones, minimizing noise introduced by unstable power sources. The additional +12V output increases compatibility with microphones or inline preamps that use lower-voltage supplies. The compact external design allows placement near the microphone source or in a rack setup, reducing cable runs and electrical interference. Built-in protection and regulated outputs help maintain stable voltage under varying load conditions.
Suitable for
 Studio recording of vocals and instruments with condenser XLR microphones
 Live sound reinforcement when mixing desks lack phantom power
 Podcasting setups using XLR condenser microphones
 Field recording rigs that require a compact external power solution
Key specifications
 Phantom power output: regulated +48V for XLR microphones
 Auxiliary output: regulated +12V for compatible microphones or inline devices
 Connector type: XLR outputs designed for microphone powering
 Form factor: compact external power supply suitable for tabletop or rack placement
 Protection: built-in regulation and overload protection to maintain stable voltage
How to use
Connect the Mozos PS400 between the microphone and the preamp or mixer using an XLR cable, selecting the +48V output for standard condenser microphones or the +12V output when a lower-voltage supply is required. Ensure cables are securely connected and that the receiving device input is set to accept a mic-level signal. Power the unit from its mains input and verify voltage output with the microphone connected. Adjust microphone positioning and preamp gain as usual; the external power supply will provide the necessary operating voltage without affecting gain staging beyond enabling the microphone to function.
Usage recommendations
Use balanced XLR cables of good quality and keep cable runs as short as practical to reduce the risk of noise. When using the +12V output, confirm compatibility with the microphone or inline device to avoid improper voltage application. Store the unit in a dry, ventilated environment and avoid exposing it to extreme temperatures or moisture for reliable long-term operation.
