Radial Introduces the McBoost Preamp for Dynamic and Ribbon Microphones

Wednesday 11 November 2015 By Lizanne

It's a common occurrence in the studio or during live performances - you make a recording, but the signal is low, the fader on your console is on max and you're out of headroom. The signal is simply too weak and starts to distort when you try to amplify it with a compressor or gain plugin. Radial comes to the rescue with the McBoost - a microphone preamplifier that will add up to 25 dB to the incoming signal, ideal for consoles or audio interfaces that need a little extra oomph!
