A Neve Module for Your 500 Series Rig

The first 500 series module designed by Rupert Neve, the 517 microphone preamplifier/compressor, brings fantastic sound quality and tone shaping capability to your 500 series rack. True to the lofty standards of Rupert Neve Designs, the 517 boasts transformer-coupled circuitry for untainted sound and an incredibly versatile feature set. The 517's preamp section, which is based closely on the full-sized 5017 design, sports 66dB of gain and an interdependent direct input with 30dB of gain. The mic preamp includes phantom power and phase reverse, and the instrument input includes a ground-lift switch and instrument thru function.

One of the things that separates the 517 from other 500 series modules (and preamp in general) is its capability to blend both microphone preamplifier and the direct input together, giving you the option of combining, for example, the sound of a bass cabinet with the direct bass signal as you track. To go with this function, the 517 also features Neve's Vari-Phase control, which allows you to adjust the relative phase between the preamp and DI. When used with just the preamp or DI, this same Vari-Phase function allows you to continuously adjust the phase of your signal, an option which gives you considerably more control over how the tone balances in the mix compared to only a standard phase switch.

The compressor section of the 517 is equally as refined at the preamp section. This compressor uses a genuine LDR (light dependent resister) to achieve true opto compressor smoothness. In the tradition of many of the most heralded opto compressors, the 517's compressor section has a fixed attack, release, and 2:1 ratio, allowing you to dial in the degree of compression with a single threshold control. Finally, the 517 also features Neve's famous Silk function, which subtly enhances the signal by reducing negative feedback and shifting the 517's frequency response slightly. If you're unfamiliar with this effects, it's incredibly sweet and musical.

Great MicPre/Comp

517 is a real big step up for me after TL Audio. Incredible sound, incredible compressor (in spite of the fixed ratio and fixed attack&release times).
Music background: Producer

Nice fixed compressor

I combined it with an API 550A.........nice sweet sound. Tried it with vocals and a Neumann 193, bass thru the DI, guitar cab........smooth controlled sound. Very musical and clean. I see lots of potential for this preamp.

A. Not an A+

This is a good preamp. I worked on a 5088 for about a year, tracked lots of guitar and bass... some drums... some vocals. These pres really shine on guitar and bass. Nice, big, round bass. They are quite forgiving on heavy distortion guitar and smooth on clean guitar. Drums sound good, too. This is just a great pre... it is not even close to a 1073 or 81.... but it is just an entirely different beast. With the addition of the vari-phase and compressor, this is a tough one to beat. Get 2 and you will not be disappointed.
