The PreSonus TubePRE Microphone Preamp lets you add character to your signal by varying the amount of gain and tube drive. A 12AX7 tube in this single-channel mic preamp fattens your signal while dual-servo gain stages let you simultaneously output to your amp and console. Sterling specs include 10Hz-80kHz frequency response, a 94dB noise floor, and >90dB S/N ratio. Capacitor-free circuitry and wide dynamic control give you a big boost without noise. Includes 48V phantom power, phase reverse, 20dB pad, and 80Hz rumble filter. A large VU meter with a cool blue backlight keeps you informed. Balanced/unbalanced and XLR I/O give the PreSonus TubePRE flexibility. Great as a studio direct box.
