A new era of preamp portability
Maker Hart, famous for their tiny mixers, now brings you the equally tiny Just Mic Power, a microphone preamp that makes it possible to connect any condenser or electret microphone to your mixer, phone, computer or other recording devices. Microphones that require phantom power or plug-in power, as is the case with many professional condenser mics, lapel/lavalier mics, etc., can now be used with any mixer or device.

Powered by USB, the Just Mic Power can be connected to USB power banks or by using the included power supply, making it both versatile and easy to take on the go. Finally, a preamp that fits in the palm of your hand and can power virtually any popular microphone on the market! (Note: Just Mic Power does not contain batteries and must be powered externally.)

Well connected
Despite its tiny size, the Just Mic Power preamp has a standard XLR input as well as a 1/8" (3.5 mm) audio jack input. On the output side, it features a 1/8" output jack as well as a 1/8" monitor headphone output. Output is managed by a volume knob and there is a red indicator LED to show power is on. Need to sneeze? Press the handy MUTE button! The MUTE button also features a backlight to let you know if it's on.
