Microphone preamplifier

LMNOPRE

A custom-shop preamp that is not a reissue of anything.

The limited edition Lmnopre Microphone Preamplifier is not another reissue of a vintage design, but a totally NEW microphone preamplifer. It not only sounds fantastic, but gives you new options allowing you to explore deeper into the control of sound.

LMNOPRE, front
what it does
  • A fully discrete gain stage with up to 74dB of clean, quiet, gain with a maximum level out of 31dB
  • A completely differential circuit topology from input to output
  • Low frequency resonance control allowing a controlled resonance creating (amongst other things) a tune-able proximity effect without being in close proximity of the microphone.
  • Selectable fully variable phase alignment the same circuit topology as the award winning Little Labs IBP phase alignment tool.
  • Phase alignment/output level trim section line level insert allows you to use the phase align and output attenuator section separately from the mic pre.
  • Front panel direct injection system utilizing its own custom xfrmr with two inputs, one passive for use with active instruments, and one active for passive pickups.
  • Rear panel external mic input Xfrmr connector allowing optional external mic Input xfrmrs to be selected by the user for special applications.
  • Switch selectable post output transformer output level trim allowing controlled transformer saturation without overloading post microphone preamplifier devices.
  • Output transformer front panel bypass switch
