The Rupert Neve Designs Portico 5017 Mobile Mic Pre/DI/Comp is a portable, high-quality preamp that offers simultaneous mic/DI operation with blend and variable phase controls, Silk effect, and a single-knob compressor
Portable high-quality mic preamps are generally a single channel mic preamp with an instrument input that lets you use one or the other. The Portico 5017 Mobile Mic Pre/DI/Comp not only gives you the industry leading sound of Rupert Neve, but also lets you use the mic preamp and the DI simultaneously. The Portico 5017, along with Neve’s famous silk effect, features a blend control for the mic and DI, along with a vari-phase control that enables you to align the phase of a miked amp with a simultaneous DI signal—a procedure commonly used on bass and electric guitar. An innovative departure from the ordinary in the annals of studio and mobile recording or live performance, the 5017 Mobile DPC also adds single-knob compression to its powerful features, in a go-anywhere design.

Simultaneous use of Mic and DI inputs
The 5017 offers what is, in essence, two studio-quality Neve channels for the price of one that singer-guitarists, a duo, or a bassist can take anywhere. You can use the DPC for a vocal mic pre and compressor, as well as a separate DI preamplifier via the blend control (blend off).) 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.
Single-channel blended use
As a single-channel device for instruments, the 5017 can be used to phase-align, combine, and compress direct and amplified signals. To achieve this, use the DI for the instrument’s direct signal, and the mic preamp for the speaker cabinet. The blend control mixes direct and amplified signals to achieve the desired tonal blend between the two sources, while the variphase is used to adjust phase-cancellation between the two signals. To compress the blended signal, the internal compressor jumper must be set to the blend path (this is the default setting). This technique could also be used to create a single, mixed output of guitar and vocals.
Vari-Phase control for blended use
In addition to its standard polarity-reverse switch, the 5017 has a “variphase” control to adjust the phase incrementally. This control is useful when two signals combined from the same source arrive at different times. For example, the combination of close-miked drums and overheads more often than not, arrive out of phase, which results in the hollow sound of phase cancellation. 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. Since there’s always a delay between direct and miked signals, a bassist using both can blend the two into a single output, using the variphase 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.
Using a new light-dependent resister (LDR) design, the 5017’s opto-coupler compressor has been simplified to a single threshold control with auto make up gain. When signals exceed the threshold level, gain is reduced at a controlled 2:1 ratio. An internal jumper can be set to change attack and release times to standard or fast. 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.
