Rupert Neve 5017 Mobile DI, Mic Pre and Compressor with variphase
Mobile DI, Mic Pre and Compressor with variphase
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. In
replacing the Portico 5016 Mic Pre / Variphase DI, the 5017 Mobile DPC
adds single knob compression, DI / Mic Pre blending, and a go anywhere
design to a well established classic.
With Portico Series custom transformers and silk mode, the Mobile
DPC’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.
Dual Channel Use
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.
Blended Use
Used 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 signal. The blend control is used
for mixing direct and amplified signals to achieve the desired tonal
blend between the two sources, and the variphase is used to minimize or
extenuate phase cancellations 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 a guitar and vocals.
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 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.
Vari-Phase
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.
With the 5017, the Portico sound is always within reach.
