With two channels of the classic tone you know and love, 72dB of gain, sweepable high-pass filters for precise control, and the power of Mr. Rupert Neve's dual-tap transformers with variable Silk saturation, the 5211 delivers a versatile, flattering, and uncompromising front end for any signal path. In short, it's everything a mic preamp should be.

History and Evolution The very first product from Rupert Neve Designs was the beloved 5012 Duo Mic Preamp, and the 5211 represents a dramatic evolution of the 5012's features, circuit design and form factor, all brought together with the custom output transformer from the flagship Shelford Channel.

First amongst the updates is the addition of variable Silk, which saturates the class-A output stage in the way that only a Rupert Neve Design can. This dials the harmonic content up to and beyond that of Rupert's classic designs, while still providing the option of a pristine, open & modern sound when disengaged. The amplifier circuity has also been refined and updated with higher voltage +/-21V rails for improved signal-to-noise ratio, superb headroom and tremendous dynamic range - a hallmark of Rupert's evolved designs over the last several decades.

Complementing the Silk circuit is the custom-designed output transformer from the renowned Shelford Channel, which uses Rupert Neve Designs' dual-tap output topology. This offers both full-headroom (+26dBu) and -6dB outputs, allowing the engineer to drive the unit fully into classic transformer saturation without clipping converters and other devices later in the chain. The 19" 1U chassis provides the space required for a robust internal auto-switching power supply, which provides ample, stable power anywhere in the world. Finally, the faceplate has been powder-coated in the distinctive "Shelford" color for an unmistakably classic look.

The "Best of Both Worlds" Design Unlike the Shelford Channel, which uses a mic input transformer for a more vintage topology, the 5211's input is fully transformerless, maximizing signal clarity direct from the microphone. Combined with the more extreme saturation from both variable Silk and the custom output transformer's lower-headroom tap, the 5211 is capable of producing tones ranging from thick & warm to breathtakingly delicate & clear. It's the best of old and new alike.

Preamplifier Details The microphone input is balanced but not floating, using a Transformer-Like-Amplifier (T.L.A.) configuration to capture the microphone's signal in as pure a manner as possible. With the +48V phantom voltage switched off, this input serves as an extremely high quality line input with an impedance of 10K Ohms. Each channel features 72dB of extraordinarily low-distortion, low-noise gain using a stepped switch in 6dB increments with a continuously variable +/-6dB trim. Individually selectable polarity, +48V phantom power, and a swept high-pass filter from 20-250Hz are available to further control the input, with Silk control available for the outputs.

Silk What is Silk In brief, Silk is a tonal option applied within the unit's output stage that manipulates the signal's harmonic content to create the sonic character associated with Rupert Neve's vintage modules. By reducing negative feedback and saturating the output transformer while adjusting the frequency spectrum, Silk provides a sweet, musical enhancement of the input signal - and when the level is driven to the edge of its headroom, the Silk's effect is multiplied.
