## Summary description

Mackie M 48 is an external 48V phantom power supply designed to provide stable phantom power for condenser microphones and other audio equipment requiring 48 volts. The unit delivers standardized 48V phantom voltage to XLR-equipped devices, enabling professional microphone operation in recording, broadcast, live sound, and studio setups where onboard phantom power is unavailable or insufficient.

## Long description

The Mackie M 48 48V External Phantom Power is a dedicated external power supply that provides standardized 48V phantom power to condenser microphones and other XLR-equipped audio devices. Designed for situations where onboard phantom power is unavailable or insufficient, this unit supplies a stable DC voltage to ensure reliable microphone operation in recording, broadcast, live sound, and studio applications. The compact external format allows flexible placement and easy integration with mixers, preamps, and microphone chains.
Advantages
The Mackie M 48 offers stable and standardized 48V output appropriate for most professional condenser microphones. Its external design removes dependence on a console or preamp's internal phantom supply, reducing the risk of noise or voltage fluctuation affecting microphone performance. The unit is compatible with XLR-wired devices and is intended to maintain proper polarisation and headroom for sensitive capsules, improving consistency across recording and live setups.
Suitable for
 Condenser microphones that require 48V phantom power
 Portable recording rigs and external microphone preamps without built-in phantom power
 Broadcast and podcast setups where a reliable external supply is needed
 Live sound and stage applications requiring remote phantom sourcing
 Studio workflows that use multiple standalone microphones or DI boxes with XLR inputs
Key specifications
 Output voltage: 48V DC phantom power
 Output connector type: XLR (balanced output for microphone use)
 Intended use: External phantom power supply for condenser microphones and XLR devices
 Compatibility: Standard XLR-wired condenser microphones and audio equipment requiring 48V
 Form factor: External compact power unit for portable or rack-adjacent placement
How to use
Connect the Mackie M 48 to the microphone or input device using an XLR cable, ensuring the cable and connectors are properly seated. Power the unit according to the manufacturer's instructions (use the correct mains or DC input as specified) and verify the 48V indicator if present. Once active, the unit will supply phantom voltage to the connected condenser microphone; confirm the microphone's operation by monitoring signal levels on your preamp, mixer, or audio interface. Disconnect power before connecting or disconnecting microphones when possible to avoid pops or transient signals.
Usage recommendations
Use quality XLR cables and place the external phantom supply away from noise sources and strong electromagnetic fields. If multiple microphones require phantom power, verify each microphone's specifications and avoid supplying phantom to devices that do not require or are incompatible with 48V. Regularly inspect connectors and cables for wear to maintain reliable audio performance.
