The Rupert Neve Designs Portico 5017 is a desktop format +66dB mic preamp with "Silk" function/ +30dB direct box / single-knob compressor. The preamp and DI sections can be used separately, and the compressor can be applied to the mic preamp with an internal jumper. A blend control allows the user to dial in 100% mic, 100% DI, or any mix of the two.

The 5017 features a variphase control to variably alter the phase relationship between the mic and DI signals. The optical compressor has a fixed 2:1 ratio, a single threshold control, and an internal jumper to select a faster time constant.
