Rupert Neve Designs 5211: 2-Channel Mic Preamp

Overview: The Natural Evolution of a Classic

The 5211 is a modern reimagining of the microphone preamp designs that made Rupert Neve a household name in audio recording. Combining the classic tonality of vintage units with updated technical precision, the 5211 provides two channels of high-gain, low-noise amplification. Rupert Neve Designs engineered this unit to be a versatile front end for any signal path, offering a simple and elegant interface that delivers uncompromising sonic performance for everything from delicate vocals to high-pressure instrumental recordings.

Key Features & Benefits

• 72dB of Pristine Gain: The 5211 features a 12-way precision rotary switch for coarse gain adjustment, paired with a continuously variable trim. This allow for the perfect gain staging of any source, whether using low-output ribbon microphones or loud line-level inputs.

• Variable Silk and Texture: A standout feature of the 5211 is the Red Silk circuit. When engaged, this reduces negative feedback on the output transformer to add musical harmonic saturation. The Texture control allows engineers to dial in the specific amount of “color”—from a subtle vintage sheen to a thick, harmonically rich character.

• Dual-Tap Custom Transformers: The custom-wound output transformers feature a unique dual-tap design. This provides both a standard MAIN output and a secondary -6dBu output, allowing the preamp to be driven hard for transformer saturation without clipping the converters of the next device in the chain.

• Sweepable High-Pass Filter: To eliminate unwanted low-frequency rumble or mud at the source, the 5211 includes a continuously variable Sallen-Key high-pass filter. This filter is sweepable from 20Hz to 250Hz, providing precise control over the bottom end of the signal.

• Discrete Class-A Topology: By utilizing +/- 24V discrete Class-A circuitry, the 5211 maintains the highest possible signal integrity. This design philosophy ensures that the preamp remains transparent and lifelike, even when pushed to the edges of its headroom.

• Concurrent Output Usage: Both the MAIN and -6dBu outputs are active and can be used simultaneously, offering flexible routing options for tracking and monitoring.

• Professional Metering and Control: Each channel is equipped with an eight-segment LED bar-graph meter for monitoring output level, along with dedicated switches for 48V phantom power and polarity reversal.
