The Rupert Neve Designs Portico 5017 Mobile DPC adds single knob compression, DI / Mic Pre blending, and a go-anywhere design to a well established classic.

Comprised of a rugged, portable chassis with world-class Portico pre-amp, compressor and DI circuits as well as two-channel operation, variphase, silk and DI/mic blending capabilities, the Portico 5017 is an innovative and powerful tool for recording or live performance.

With Portico Series custom transformers and silk mode, the Rupert Neve Designs Portico 5017's sonic signature is nothing short of legendary. It's the 5017's revolutionary feature set however that make it an indispensable tool for studio recording, live recording and stage performances.

Used as a two-channel device, a lead singer and guitar player, can take the classic studio quality of the 5017 wherever they go; using the DPC for a Vocal mic pre and compressor, as well as a separate DI preamplifier.

To achieve this, the blend control should be selected as fully DI (blend off), and an internal jumper can be selected to apply the compressor to the mic pre signal. When engaged, Silk mode would effect both vocal and guitar tracks, and the HPF control would effect only the mic path.

Based around a new LDR (light dependent resister) design, the 5017's opto-coupler compressor has been simplified to a single threshold control with auto make-up gain. By default, the compressor is set to a fixed 2:1 ratio with an internal jumper to change between standard and fast time constants.

To set the compressor, simply dial the threshold control down until the desired amount of compression is achieved. An LED light indicates when the compressor is active. Two internal jumpers in the 5017 can be set to change the compressor from the mic channel to the di/blend channel, and to change the compressor time constant from standard to fast.

In addition to the standard polarity reverse, the 5017 also incorporates a vari-phase control to adjust the phase incrementally. This control is useful any time two signals derived from the same source are combined.

For instance, even with careful placement, the combination of close miced drums and overheads, can often yield hollow sounding results. By using the variable phase adjust, the direct signal can be phase rotated until the signals are naturally aligned.

This technique is also extremely useful when combined with the internal blend control on instruments. A bassist, using both direct and miced signals can blend the two into a single output, using the vari-phase to reach an optimal alignment. By adjusting the phase in the 5017, the musician or engineer can find the absolute best mic position without regard to the phase relation to the direct signal.
