With a big, bold preamp and the flexibility of variable Silk/Texture, Rupert Neve designed the 511 to combine classic sonics with 500-series value. Incorporating the 517’s powerful preamp, the 5012’s universally useful sweepable high pass filter, and the transformer-saturating power of a variable silk circuit derived from our flagship Portico II Channel, the 511 is a Rupert Neve-designed micpre for the masses.
Designed for 500 Series by Mr. Rupert Neve
Rupert Neve: “While creating functional 500 series modules is relatively simple, designing those modules to equal their non-500 series counterparts with the current, voltage and space restraints is quite challenging. In creating our own 500-Series Modules, we experimented with a number of different transformer and circuit designs to achieve the same presence and sweetness found in the Portico Series of modules. The result of these efforts is that outside of the slightly lowered headroom, our 500 series modules are nearly indistinguishable from standard Portico Series modules, and are perfectly suited for studios of the highest caliber.”
Input signals may be derived from Mic or Line sources (make sure 48V is off for line sources!). The input has a 10K Ω non-reactive input resistance that handles a full 22dBu signal without the need for a pad. The pre-amp is a TLA non-reactive design that precludes the loading of microphones with limited driving capability. A primary gain control provides 66dB of gain in 6dB increments for easy recall, with a +/- 6dB trim for fine adjustment. For condenser microphones and powered DIs, there is +48V phantom power. A transient-optimized HPF continuously covering the range from 20-250Hz is included to tame rumble and proximity effect.
One of the key developments in the 511 is the Red Silk / Texture control from the Portico II Channel. Building on the “Silk” mode found in the Portico Series mic pre-amplifiers, Texture is designed to adjust the actual amount of harmonic music content from the source material, in effect, providing wide range of tonal options for the preamplifier. Like the original Portico Silk, the Silk Red / Texture works by reducing negative feedback on the output transformer and adjusting the frequency response to more closely resemble Mr. Rupert Neve’s vintage designs. With the 511, the Texture control allows these techniques to be pushed further than previous designs, adding about 10 times the desirable THD of the original silk control at its maximum setting.
With that said, we have taken great care to ensure that the musical integrity of source material itself will not be compromised by these harmonic controls (these are not to be confused with controls from other manufactures that may “incinerate”, “demolish” or “destroy” source material), and we believe they can be confidently utilized to fit the personality of any song, instrument or engineer.
Low Noise, Low Distortion Operation
Much care was given in designing the 511 to produce as little noise and non-harmonic distortion as possible. Carefully implemented signal paths and Class A operation are a large part of the 511’s sweet, whisper quiet performance.
How are you guys finding the RND 511 to compare to the API 512c?
...second part is me playing acoustic steel string in DADGAD tuning the recording chain is: Beyer m160n > Cloudlifter CL2 > Rupert Neve Designs 511 > Audient iD22 (insert input to bypass the preamps, straight into the AD converter) there is no EQ, HPF or compression of any kind, just the raw unprocessed sound.
Got my 511 today and I'm really, really pleased with it. Excellent pre. Smooth, smooth highs with reminiscent Neve lows. Mids are smooth as well and didn't stick out on Vox or guitars. The highs seem to be more open like my Helios and has more bottom than the Helios. The silk button and adjustable...
I've been using my 511 as my "money" pre since April or so. I was looking for an inexpensive pre that had both a HPF and a trim out, so I can play with saturating the input stage. Add the 'silk' control and a useable meter, and you've got a lot of features in a 500 preamp.
This is apparently...
I've had a pair for about 8 months now. I love the sound of these guys, I have some other nice pres, these are the most versatile. Really nice mids and highs, really smooth sounding. The variable HPF is really musical and is great for keeping tracks clean. The texture knob is my favorite part, I...
I've been using a pair of these for a month or so now. I'm very happy with them.
I know everyone talks about the silk/texture features a lot, but let me just come right out and say that this pre doesn't need those features to sound great. It sounds great "as is" and the silk & texture features...
