Product Overview

The Infinite Masterpiece of Valve Technology

The Sontronics MERCURY stands as the absolute crown jewel of Sontronics' microphone lineup, developed in collaboration with top-tier British producers and engineers at Abbey Road Studios. Engineered with ultra-premium components boasting a rare less-than-1% electrical tolerance, this large-diaphragm valve microphone provides an incredibly clean signal with massive low-frequency depth and coherent high-end transparency. From solo vocals and voiceovers to pianos, strings, and full orchestral miking layouts, it serves as the ultimate default studio workhorse.

Product Description

European Valve Architecture and Sweepable Polar Choices:

The soul of the MERCURY is fueled by a hand-selected ECC81/12AT7 vacuum tube, delivering a luxurious, rich harmonic profile that gives tracks immediate presence and weight. Rather than locking you into fixed steps, the included master power supply unit features a continuously sweepable rotary control. This unlocks an infinite choice of polar patterns—morphing fluidly from wide omnidirectional, through every variation of cardioid, down to a tight figure-of-eight, and everything in between—allowing you to dial in the exact acoustic balance of direct sound and room reflections.

Exceptional Headroom and Medical-Grade Power Paths:

Built to meet the demands of high-fidelity tracking spaces, the microphone maintains an exceptionally low self-noise floor under 12dB (A-weighted), which is almost unheard of for a multi-pattern tube microphone. Its internal engineering ensures outstanding phase coherence between its dual-diaphragm plates. Powered by a custom external supply unit fitted with an integrated medical-grade interference filter, the MERCURY receives flawless voltage stabilization completely isolated from mains electricity hum or wireless ground lines.

Premium English Craftsmanship and Deluxe Wood Packaging:

The physical bottle-style design of the MERCURY is a testament to top-tier industrial construction, optimizing headbasket air spacing to enhance vocal and instrument clarity. Onboard control options include a switchable -10dB attenuation pad for high-volume brass, drum overheads, or guitar stacks, and a 75Hz high-pass filter to sweep out undesirable low-end stage rumble. Reflecting its premium status, the entire system comes completely packaged with a bespoke wooden display box, a heavy-duty spider shockmount, and a tour-grade aluminum flight travel case.
