The Audio-Technica AT8801 single channel phantom power supply module provides 48V phantom power for a single microphone, and allows the use of remote powered microphones with systems that do not provide phantom power. It features a highly regulated power supply that delivers a constant voltage source, even with a heavily loaded input. The regulator IC is internally protected to prevent overheating or damage even if shorted. The rugged steel case is finished in enamel and provides shielding from electrostatic interference. Includes plug pack power supply.
