This dual-channel microphone preamplifier is a refined version of the historic Langevin AM-4 console channel. Manley developed their own discrete gain stage to provide for balanced outputs to bring the Langevin into the modern age whilst retaining the great sought after tone that well designed discrete circuitry can deliver. No ICs in this unit! They also added 1/4" DIRECT INPUTS accessible at the rear panel. The continuously variable plus and minus 10dB shelf EQ's switched turnover points have been chosen carefully at 40 or 80Hz (LF) and 8 or 12KHz (HF) and the EQ can be bypassed or set to 'flat'. Up to 53dB of gain is available to accommodate a wide range of microphones plus 48 volt phantom power. As the single most important component in a mic preamp is the input transformer, this unit features Manley's own precision transformers, wound in their own factory, delivering a natural sound with a touch of brawn that good iron provides!
