With a big, bold preamp, a swept high-pass filter and the powerful saturation control of variable Silk, the 511 combines legendary Rupert Neve tone with 500 Series value.

What is Silk?
One of the key features of the 511 is the Silk / Texture control. The Silk circuit was initially developed for the original Portico series mic preamplifiers, and was only a single switch – on or off – that added a specified amount of musical, pleasing harmonic saturation to the unit’s output stage.

Taking this concept one step further, the Texture knob is designed to adjust the actual amount of harmonic content from the source material.

So how does it work? By reducing negative feedback across the output transformer and adjusting this feedback’s frequency response, the Silk / Texture circuit provides the sweet, musical saturation found in Rupert’s legendary vintage designs – but with complete & precise control over the amount of classic tone you want.
