The Mercury M76m MK IV is the latest evolution of our renowned Studio Microphone Amplifier, inspired by the vintage Telefunken/Siemens V76m. Used in European broadcast and recording studios in the 1950s and 60s, these classic modules were revered for their unparalleled sound quality. The M76m MK IV revives this iconic tone with modern enhancements, providing today's engineers with a versatile and powerful tool.
Vintage Inspiration, Modern Innovation
The Mercury M76m MK IV stays true to the original V76m's legendary sound while incorporating essential modern features. By maintaining the exact circuit design, quality components, and transformers, we've ensured the same warm, open tonality. Our updates include features like Phantom Power, Phase Reversal, and a High/Low Impedance switch, all designed to enhance usability and flexibility.
Exceptional Build Quality
Each M76m MK IV is crafted with precision, featuring four transformers and four tubes per channel. This meticulous construction guarantees the highest audio fidelity and durability, making it a reliable choice for professional studios. Components like custom USA-made transformers, WIMA caps, and DALE military-grade resistors ensure top-tier performance.
Innovative Features and Controls
The M76m MK IV is equipped with an array of controls for unparalleled flexibility:
- Gain Control: Adjustable from 0 to +60dB in 6dB increments, allowing precise level setting.
- Level Control: Functions as a fader, providing nuanced gain staging and the ability to introduce musical tube "break-up."
- Output Attenuation: Ranges from -0 to -10dB for additional tone shaping.
- Impedance Select Switch: Optimizes performance for high and low impedance devices.
- Phantom Power and Phase Reversal: Essential features for modern recording.
Proprietary Mercury FDI Circuit
The Mercury FDI (FET Direct Input) circuit is based on a class-A tube topology. This J-Fet circuit ensures every nuance of a direct recording is captured, allowing the tube or solid-state character of the amplifier to define the tone. The DI signal passes through the entire microphone preamp circuitry, showcasing the unique character of each preamp.
Testimonials and Expert Endorsements
Renowned audio professionals, including John Hill (Florence + The Machine, Charli XCX), have praised the M76m for its versatility and stellar sound. TapeOp Magazine's Pete Weiss describes it as potentially the ultimate vintage-style mic preamp available today, highlighting its tonal flexibility and modern conveniences.
Mercury M76m vs. M72s
While both models excel in different applications, the M76m is known for its open, airy sound, making it ideal for vocals, bass, and guitars. With nearly 70dB of total gain and high/low impedance options, the M76m also excels in room and overhead mic applications.
