Designed by industry visionary Paul Wolff , the SPM5 features a Class A discrete front end while utilizing the same TX100 output transformer used in our Tonelux products.  The Radiance control adds the right amount of filtering creating a presence of 2nd order harmonics without increasing your gain.

A 70 Hz HI Pass filter was added to eliminate unwanted low end and rumble from your tracks. An impedance switch allows your preamp to work properly with Ribbon microphones that have a 50 Ohm load, and on the front panel is a combo XLR/1/4" jack making it easy to use different microphones as well as D.I. boxes.

 Features

  • Mic, Instrument, Line Level Inputs
  • Radiance Control for Harmonic Distortion
  • Adjustable Input & Output Gain Controls
  • Selectable Impedance for Ribbon Mics
