This dual-channel microphone preamplifier is our refined version of the historic Langevin AM-4 console channel. We developed our own discrete gain stage to provide for balanced outputs to bring the Langevin brand into the modern age while still retaining that desirable tone that discrete circuitry delivers.
No IC’s in this unit, please! We also added 1/4" DIRECT INPUTS addressable from the rear panel. The continuously variable plus and minus 10dB shelf EQ’s switched turnover points have been chosen carefully at 40 or 80Hz (L.F.) and 8 or 12KHz (H.F.). All EQ can be completely switched out or set to ‘flat’ positions. Up to 53dB of gain is available to accommodate a wide range of microphones and high-current 48 volt phantom powering is built in.
Because the most single influential component in a mic pre has to be the input transformer, this unit features our precision MANLEY mic input transformers which are wound right here in our factory, for that natural sound with a touch of brawn good iron provides.
