Warm Audio Sound Techniques Jude Stereo Microphone Preamp

The Warm Audio Sound Techniques Jude Stereo Microphone Preamp is an official collaboration between Warm Audio and the legendary British console manufacturer Sound Techniques, bringing the authentic sound of the original A Range console preamp to modern recording studios. Designed from the original schematics by Geoff Frost, the engineer behind the iconic Sound Techniques consoles at Trident Studios, Jude faithfully recreates the complete signal path that helped define some of the most celebrated recordings in music history. Its genuine dual discrete Class A circuitry, custom CineMag transformers, premium audio grade components and hand-wired construction deliver the unmistakable warmth, depth, and musical detail associated with classic British recordings.

Unlike modern recreations inspired by vintage designs, Jude features the original Sound Techniques preamp circuit, preserving every element that made these consoles so highly regarded by engineers and producers. The unique 9-position Z Match impedance control allows microphones to interact differently with the preamp, unlocking a wide range of tonal possibilities whilst maintaining exceptional sonic integrity. Whether recording vocals, guitars, piano or drum overheads, Jude offers remarkable clarity, punch and harmonic richness. Built to exacting standards, hand tested in Austin, Texas and backed by a five-year warranty, the Jude Stereo Microphone Preamp delivers authentic analogue character and legendary console performance for today's professional studios.

• Authentic Sound Techniques A Range Console Circuit - Designed directly from the original Sound Techniques console schematics, delivering the genuine stereo preamp sound that shaped countless classic British recordings.
• Original Z Match Impedance Tone Control - The unique 9-position impedance control optimises microphone interaction, providing a wide range of tonal character and gain response with vintage and modern microphones.
• Premium Hand-Wired Construction - Built using custom CineMag transformers, Nichicon and Wima capacitors, carbon resistors and carefully hand-wired construction for authentic console performance.

Original British Console Sound:

The Jude Stereo Microphone Preamp captures the unmistakable character of the original Sound Techniques A Range consoles installed at London's renowned Trident Studios. Developed in partnership with Sound Techniques, every aspect of the preamp follows the original design, including its dual discrete 3035 Class A amplifier stages and carefully selected components. Rather than simply recreating the sonic character, Jude reproduces the genuine signal path responsible for the warmth, punch and musical detail heard on landmark recordings by artists including David Bowie, Elton John, Queen and Paul McCartney.

Versatile Tone Shaping with Z Match:

One of Jude's defining features is the original Z Match impedance control, which allows engineers to fine-tune how microphones interact with the preamp. Offering nine tonal settings across multiple impedance values, it provides subtle and dramatic changes in gain structure, transient response and overall character. This flexibility makes it equally suited to ribbon, dynamic and condenser microphones, helping users discover new sonic textures whilst preserving the natural qualities of every source.

Built for Professional Recording Studios:

Every Jude Stereo Microphone Preamp is manufactured to the demanding standards specified by Sound Techniques. Hand-wired construction, premium Nichicon and Wima capacitors, carbon resistors and custom-wound CineMag transformers ensure exceptional reliability and sonic consistency. Dual channel operation makes it ideal for stereo recording applications, including drum overheads, acoustic instruments, piano and room microphones. With comprehensive connectivity, low noise performance and a five-year warranty, Jude is built to deliver dependable results for years of professional studio use.
