The Mackie M48 is a phantom power supply designed to provide 48 VDC phantom power to a single microphone for musicians, producers, and audio engineers in live stage applications and home, project, and mobile-recording studios. Connect it between your microphone and preamp to supply a steady stream of phantom power. It features a balanced XLR 3-pin input and output for compatibility with most microphones and sturdy heavy-gauge steel construction for dependable use on the road or in the studio.


Its circuitry yields noise-free operation that won't color your sound. Power it via a 9V battery or the supplied AC adapter and check power and low-battery status via LED indicators.
