A 12AX7 tube in this single-channel unit fattens your signal while dual-servo gain stages let you simultaneously output to your amp and console. It also lets you add character to the signal by varying the amount of gain and tube drive. Sterling specs include 10Hz-80kHz frequency response, a 94dB noise floor, and >90 dB 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 offer flexibility.
