Sontronics Mercury

The Mercury is a valve condenser microphone, meaning it uses a vacuum tube to impart a specific warmth and harmonic richness to the signal. Unlike standard solid-state condensers, this tube-based design offers a more vintage, musical character that is particularly effective for smoothing out digital recordings.

The Mercury includes a dedicated external power supply unit that features a sweepable dial. This allows you to infinitely adjust the polar pattern anywhere between omnidirectional and figure-of-eight, giving you precise control over how much room sound or off-axis rejection you capture.

Yes, it is well-equipped for high-SPL sources. It features a switchable -10dB pad, which prevents the microphone from distorting when capturing louder sound sources, making it versatile enough for everything from delicate vocals to aggressive guitar cabinets.

The 75Hz low-cut filter helps clean up your recordings by removing unwanted low-end rumble, such as air conditioning noise or stage vibrations. It is a useful tool to have engaged during tracking to save you from having to fix muddy frequencies during the mixing stage.

The Mercury uses a hand-selected, European-made ECC81/12AT7 tube. While these are durable, they are glass components that can degrade over many years of heavy use; however, they are standard types that can be replaced by a qualified technician if the sonic performance ever changes.

With a self-noise rating of less than 12dB (A-weighted), the Mercury is exceptionally quiet for a tube microphone. This low noise floor ensures that you can capture intimate details and quiet performances without introducing distracting hiss into your signal chain.
