Rupert Neve Designs Portico 5017

Classic tone and control on the go.

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

TWO CHANNEL OPERATION

With two transformer coupled outputs, the 5017 has separate line outputs for the DI/Blend and Mic signals when the blend control is set to fully DI. The mic output is always independent.

SILK

Pushing the Silk button engages the Silk circuit, which enhances the source’s harmonic content in a manner very reminiscent of many of Rupert’s class-A vintage designs.

MIC GAIN

A 12-way precision rotary switch covering Line (0) and Mic from 0 to 66 dB in 6 dB steps.

INST GAIN

Continuous gain control from 0dB to 30dB.

THRU & INST 1/4” PHONE JACKS

Balanced or unbalanced Hi-Z input for instruments, with a THRU output to send signal to an amplifier.

+48V PHANTOM POWER

Provides 48V phantom power to microphones. Controlled by a switch on the back of the unit.

HIGH PASS FILTER

The high pass filter is a valuable aid in any signal chain, but particularly so in a microphone preamplifier. Signals below 80Hz can be attenuated at a rate of 12db / octave, getting rid of building rumble, motor hum, etc.

POLARITY

Push button inverts the polarity of the mic input signal path. The symbol “Ø” is often used to denote opposite polarity.

VARI-PHASE

When engaged, the VARI-PHASE control rotates the phase incrementally, allowing two signals with the same source to be phase aligned. This control is most apparent when the signals being combined are at roughly equal levels, and is generally used when blending an instrument’s direct signal with its amplified signal, as captured by a microphone.

THE COMPRESSOR

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 fixed attack and release. 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.

INDICATORS

Indicators on the 5017 denote signal presence and clipping on both DI and mic signals, as well as compressor activation.

INTERNAL JUMPERS

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.
