Developed through an official collaboration with Sound Techniques, it brings the distinctive preamp design associated with historic Trident Studios recording equipment into a modern studio format. The circuit was designed by Geoff Frost, the engineer behind the original console design. Its Class-A architecture is intended to preserve the depth, punch, and musical character associated with the original equipment.\u003c\/p\u003e\n\u003cdiv class=\"iframe-container\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/yI63DFfcoVM\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eAuthentic Signal Path\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eJude preserves key elements of the original A-Range preamp design rather than simply recreating its general sonic character. The signal path includes a dual-discrete 3035 Class-A amplifier and the original-style impedance-matching control developed around Geoff Frost's design. This approach allows the preamp to respond dynamically to different microphones and source signals. The resulting architecture provides a broad range of tonal interaction for engineers working with both vintage and modern microphones.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eZ-Match Impedance Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 9-position Z-Match control provides variable microphone input impedance and changes the interaction between the microphone and preamp. By selecting different impedance settings, engineers can alter the response and tonal character of connected microphones. The available settings include 60Ω, 200Ω, and 1.5KΩ input impedance ranges through the Z-Match circuit. This makes the Jude particularly useful when experimenting with different microphones, recording techniques, and desired tonal responses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCustom Transformer Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eJude uses custom-wound CineMag transformers selected specifically for the preamp design. Its input stage incorporates a 3-impedance CineMag transformer, while the output stage uses a high-purity nickel CineMag transformer. These transformer stages work with the discrete Class-A circuitry to shape the overall response and character of the preamp. Premium Wima and Nichicon audio-grade capacitors are also incorporated into the circuit for a carefully selected component configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHand-Wired Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Jude is manufactured using a hand-wired construction approach based on specifications supplied by Sound Techniques. Its component selection, PCB layout, transformers, and signal path are designed around the original console architecture. The aluminum faceplate and steel chassis provide a durable enclosure suitable for professional studio environments. A VU meter provides visual level indication, giving engineers a convenient way to monitor signal levels during recording.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStudio Recording Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Jude is designed for engineers and producers seeking the character of a classic British console preamp in a dedicated single-channel unit. Its combination of variable impedance, transformer coupling, Class-A circuitry, and flexible input and output connections makes it suitable for a wide range of recording sources. It can be used with vocals, guitars, piano, drums, and other microphones requiring additional tonal shaping. The 48V phantom power, polarity switch, and line-level switch further support common studio recording workflows.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Single-Channel Console Microphone Preamp\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCircuit Design:\u003c\/strong\u003e Sound Techniques A-Range Console Preamp\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmplifier Design:\u003c\/strong\u003e Dual-Discrete 3035 Class-A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePreamp Gain:\u003c\/strong\u003e 65 to 76 dB at 40Ω Source Impedance\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 60Ω, 200Ω, 1.5KΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImpedance Control:\u003c\/strong\u003e 9-Position Z-Match\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Transformer:\u003c\/strong\u003e Custom-Wound 3-Impedance CineMag\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Transformer:\u003c\/strong\u003e Custom-Wound High-Purity Nickel CineMag\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCapacitors:\u003c\/strong\u003e Nichicon Audio Grade and Wima\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEquivalent Input Noise:\u003c\/strong\u003e -128 dBu, A-Weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelf-Noise:\u003c\/strong\u003e -99 dBu, A-Weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD:\u003c\/strong\u003e 0.008%\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10 Hz to 25 kHz, ±2 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhantom Power:\u003c\/strong\u003e 48V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolarity Switch:\u003c\/strong\u003e Yes\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLine-Level Switch:\u003c\/strong\u003e Yes\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMicrophone Input:\u003c\/strong\u003e XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstrument Input:\u003c\/strong\u003e 1\/4 in.
