Mystery Magicians M808A Dual Valve microphone preamplifier

The Mystery Magicians M808A is a premium two-channel valve microphone preamplifier that combines hand-wound transformers, Class A circuitry, up to 80 dB of gain, a bypassable active filter section, and bespoke Bakelite VU meters, all meticulously crafted to deliver vintage-inspired warmth and harmonically rich tones.

Exceptional Sound Design

The M808A draws inspiration from the revered sounds of 1960s British valve consoles, yet its unique tonal character stands apart. It provides clean, warm output with rich harmonic complexity, making it ideal for enhancing microphone, instrument, and line-level signals. Its Pentode/Triode mode operation enables versatile tonal shaping, delivering everything from pristine clarity to luscious valve saturation. Adding a Saturation (THD) detecting circuit with a real-time pilot light ensures professionals can manage headroom with precision, crafting the perfect sound for any project.

Intuitive Controls for Professional Flexibility

The M808A offers responsive vintage-style controls for Filter, Gain, and Attenuate, blending the tactile experience of classic units with the precision of modern technology. Its bypassable active filter section includes four lossless high- and low-pass filters (50 Hz, 150 Hz, 2 kHz, and 5 kHz), allowing users to sculpt their sound with precision. These features ensure seamless integration into a professional workflow, whether capturing clean signals or dialling in tube-saturated warmth.

Superior Components and Build Quality

Craftsmanship defines the M808A. Class A single-ended operation and custom-designed hand-wound input and output transformers ensure it reproduces audio with unparalleled fidelity and depth. The hermetically potted transformers feature MuMetal shielding for ultra-quiet operation, while a fully regulated power supply enhances reliability. Components such as metal film resistors, film capacitors, and new old-stock matched valves further solidify its exceptional build quality, providing a classic sound with modern reliability.

Versatile Connectivity for Studio Integration

The M808A excels in its connectivity options, accommodating microphones, instruments, and line-level sources. The dedicated Direct/Instrument inputs simplify DI recording, while Line In/Out and Send/Return connectors allow seamless integration with patch bays and outboard gear. This flexibility makes the M808A a robust centrepiece for any professional studio setup, enhancing workflows and creative possibilities.

A Masterpiece of Audio Engineering

Hand-built in Los Angeles with meticulous attention to detail, the M808A reflects a commitment to excellence. Its Bakelite VU meters, manufactured with traditional ballistics, evoke a vintage aesthetic, while custom GR-style Bakelite knobs enhance both form and function. The preamplifier’s timeless design and unparalleled performance make it a trusted tool for professionals seeking exceptional sound and reliability.

The Mystery Magicians M808A sets a new benchmark in preamplifier design, combining vintage-inspired warmth with modern engineering precision. Designed to endure years of use, this valve preamplifier delivers consistent, superior performance for discerning professionals in any studio setting.
