Warm Audio Sound Techniques Jude Microphone Preamp

The Warm Audio Sound Techniques Jude Microphone Preamp brings one of the most sought-after British recording console designs to modern studios through an official collaboration with Sound Techniques. Based on the original A Range console microphone preamp found in the legendary Trident Studios consoles, Jude faithfully recreates the authentic circuit designed by Geoff Frost, delivering the unmistakable warmth, depth and musical character that helped define countless iconic recordings. From classic albums by David Bowie, Elton John and Queen to timeless recordings by The Beatles and Paul McCartney, this celebrated preamp sound has shaped generations of music.

Rather than offering a modern interpretation, Jude preserves the complete original signal path, including the dual discrete 3035 Class A amplifier, original Z Match impedance circuit and carefully selected premium components. Hand-wired construction, custom-wound CineMag transformers, Wima and Nichicon capacitors and carbon resistors all contribute to an authentic console experience with exceptional sonic performance.

The unique 9-position Z Match control provides remarkable flexibility, allowing engineers to optimise the interaction between microphones and the preamp for a wide range of tonal possibilities. Whether recording vocals, guitars, piano or drums, Jude delivers rich harmonic detail, outstanding clarity and classic British console character. Built to exacting standards and backed by Warm Audio's five-year warranty, the Jude is an exceptional choice for professional studios and serious recording enthusiasts seeking genuine vintage console tone.

• Original Sound Techniques A Range Console Circuit - Faithfully recreates the authentic microphone preamp circuit from the legendary Trident Studios consoles, delivering the unmistakable British console sound heard on countless classic recordings.
• Authentic Hand Wired Construction - Built using premium Wima and Nichicon capacitors, carbon resistors and custom CineMag transformers for outstanding reliability, performance and faithful vintage character.
• 9 Position Z Match Tone Control - Optimises microphone impedance to unlock nine distinctive tonal responses, allowing vintage and modern microphones to reveal their full sonic potential.

Authentic British Console Heritage:

The Jude is more than a vintage-inspired preamp. Developed in direct partnership with Sound Techniques, it delivers the genuine A Range console microphone preamp design that became an essential part of recording history. Designed by Geoff Frost, every stage of the signal path remains true to the original hardware, preserving the musicality, punch and harmonic richness that made the consoles at Trident Studios so highly regarded. This meticulous recreation allows engineers and musicians to capture the unmistakable sound of an iconic British recording console with complete confidence.

Premium Components and Studio Performance:

Every element of the Jude has been carefully selected to maintain the integrity of the original design. Custom wound CineMag input and output transformers provide exceptional clarity and headroom, while premium Wima and Nichicon capacitors and carbon resistors ensure consistent sonic performance. The dual discrete 3035 Class A amplifier delivers generous gain with remarkably low noise, making the preamp equally suited to dynamic, ribbon and condenser microphones. Hand-wired construction further enhances reliability and preserves the authentic console-grade build quality expected from such a faithful recreation.

Flexible Tone Shaping for Any Recording:

One of Jude's defining features is its original Z Match impedance circuit, offering nine carefully calibrated tonal variations that change the interaction between the microphone and preamp. This unique control allows subtle or dramatic adjustments to gain, frequency response and overall character without relying on additional processing. Whether capturing intimate vocals, powerful drum performances, detailed acoustic instruments or richly textured electric guitars, Jude provides an impressive range of creative possibilities while retaining the warmth, depth and musicality associated with classic British recordings.
