The Presonus TubePRE is a professional compact tube preamp featuring phantom power and low-noise dual-servo gain stage. Bulletproof steel construction means this will last you a lifetime!
You might not expect to get a professional-quality preamp with the trimmings in a 1/3U box that with a price that’s barely in 3 figures. But the Presonus TubePre is definitely all-pro, starting with a dual-servo (no capacitors) gain stage that lets you boost the program signal to smoking hot levels without significantly increasing the background noise.
The 12AX7 vacuum-tube-based preamp includes a Gain control and a Tube Drive control that lets you decide how much signal to put through the tube. You get 48V phantom power, a 80 Hz high-pass filter, -20 dB pad, and polarity-reverse switch, just like with the big preamps. And of course, the TubePre delivers that highly prized tube warmth we all love. It even sports an analogue, backlit VU meter.
The Presonus TubePre is more than a mic preamp, though. Thanks to separate instrument and mic inputs, it also serves as a dynamite direct box (DI) for guitars and basses. And it’s small enough to carry almost anywhere, although you also can rack-mount it using the optional 3UMR rack adapter.
