Description

If you have a Shure SM7B, or ribbon microphone in your audio tool box, then adding a booster preamp will ensure that you get the best results from your microphone. Mics like the SM7B, RE20, or similar large diaphragm dynamic mics, and ribbon mics, often have a pretty low output compared to condenser mics or other dynamic mics. On a quiet source, or with a low gain interface preamp, you could use some more gain.

The 7-UP preamp is a phantom powered, fixed gain pre amp that delivers 25dB of low distortion, wide bandwidth, ultra quiet gain. It combines the noiseless gain of an input transformer with the impedance matching and drive capability of active circuitry. It allows you to dial back the gain on your mixer/pre amp to it’s happy place, and still capture every delicate nuance. The 3.3kΩ input impedance lets you hear intricacies you’ve been missing. Plug your SM7B or other mics into it, and get that smooth dynamic mic sound with the sensitivity of a condenser mic.

There are other “pre” preamps, but they don’t deliver the “real world” gain of the 7-UP. They also have about 10 dB more noise, making the 7-UP both louder and quieter at the same time. And, with the 7-UP, your mic is plugged directly into a phantom blocking transformer for an extra layer of protection.
