Controlling the Portico 5045 plug-in parameters

This is a processor that accurately models the Portico 5045 Primary Source Enhancer made by Rupert Neve Designs. Operation is extremely easy, allowing you to suppress background noise that enters the mic while increasing clarity, enhancing the primary source and also improving the feedback margin. It is suitable not only for a hand-held mic but also for a lavalier mic or headset mic, and can be used in a variety of situations including event PA, concerts, or broadcast. This processor is also equipped with the audio transformer and discrete amp circuit that are the signature of the Portico series, so that simply passing the signal through it will increase the luster and depth of the sound.
