The Rupert Neve Designs' 517's mic pre is based on the TEC Award-winning Portico 5017, providing up to 66dB of gain, polarity-reverse and phantom power switches, plus the “Silk” circuit for that beautiful vintage warmth and smoothness. The separate instrument amplifier provides 30dB of gain, variable phase, a ground lift and an instrument Thru connection.

Blended Use
The 517 can be used to phase align, combine and compress direct and amplified signals when used as a single channel device for instruments. Just use the DI for the direct signal from the instrument and use the preamp for the speaker cabinet signal. Mix direct and amplified signals with the blend control while mixing to achieve the blend you want between the two sources, and use the variphase to minimize or extenuate phase cancellations. The internal compressor jumper is pre-set to the blend path by default to compress the blended signal or to create a mixed single output of guitar and vocals.

The Compressor
The 517′s opto-coupler compressor has been simplified to a single threshold control with auto make up gain, based around a new LDR (light dependent resister) design. The compressor is pre-set to a fixed 2:1 ratio with fixed attack and release.Simply dial the threshold control down until the desired amount of compression is achieved and an LED light shows you when the compressor is active.

In addition to the standard polarity reverse, the 517′s vari-phase control may be used to adjust phase incrementally. This control is useful any time two signals derived from the same source are combined. By adjusting the phase in the 517, the musician or engineer can find the absolute best mic position without regard to the phase relation to the direct signal.
