Product Description
Additional Information
  • Product Description

    The UnderToneAudio MPEQ-1 is the amalgamation of the UTA EQ and UTA's new custom mic pre. You can use the equalizer and the mic pre separately or as a complete channel strip.

    The mic pre has a custom input transformer and a carefully chosen output transformer. Both are optimized to accentuate the most flattering sonic qualities inherent in audio transformers.  The unique mic pre design makes both of the transformers bypass-able.  This offers users a choice between the detailed clarity of a Class-A transformer-less design or the vintage musicality of a dual transformer mic preamp.
