The Portico 5012 is a dual channel mic pre featuring Neve's custom input and output transformer designs. In addition to individually selectable phase, mute, phantom power and a fully sweepable high pass filter, the 5012 incorporates a Silk circuit which yields the rich warmth and presence of the renowned classic designs.
