Big Bear Audio MP1+ 500 Series

The MP1+ 500 series is the flagship unit from Big Bear Audio – designed to be a no-compromise, exceptional function preamp at a very affordable price. The MP1+ is not a replication of an existing design, or a clone of any kind. It was uniquely designed in-house at Big Bear Audio to provide engineers, producers and songwriters with an intuitive and creative microphone and instrument amplifier.

The MP1+1 combines a discrete electronically-balanced mic with the DIYRE Colour format. This means the MP1 can be used by itself as a studio reference amplifier, or in combination with any additional Colour module to transform the unit into a vast range of creative and useful tones.

In addition to quality audio features offered by the MP1, our MP1+ unit has an Elma stepped attenuator and Lundahl transformer output stage, making it the highest quality Big Bear Audio preamp and a popular purchase for audio professionals.
