Introduction
The M48 48v Phantom Power Supply allows you to use
your devices and microphones that require external power
in any setup.
Sometimes the phantom power being supplied is inadequate
as well, and with the M48, you will always get a clean,
full 48v of power for the best sound and noise performance.
Powered by either a 9v battery or supplied AC adapter.
Getting Started
The following steps will help you set up the M48 48V
Power Supply quickly.
