Reference Gold

Tube Microphone

From Manley Labs:

The Manley Reference Gold Mic represents the pinnacle of large-diaphragm tube microphone design, combining proprietary capsule technology with continuously variable polar pattern control for unparalleled versatility. Hand-assembled in California with an all-tube triode signal path, this microphone delivers exceptional transient response and tonal accuracy across all source material. Engineered to capture acoustic reality with minimal coloration, the Reference Gold provides the transparency and detail resolution demanded by world-class recording and mastering applications. Your vocals and acoustic instruments have never sounded this real!

At the core of the Reference Gold is a meticulously crafted one-inch capsule featuring a 24-karat gold-sputtered diaphragm, tensioned using proprietary techniques developed by David Josephson. The microphone body is precision-machined from solid brass with 24-karat gold plating, ensuring both optimal acoustic properties and exceptional build integrity. This attention to mechanical and acoustic detail ensures consistent performance and long-term stability under demanding professional conditions.

The Reference Gold employs an all-tube triode circuit operating at high voltage, delivering an astounding 150 dB maximum SPL capability, with exceptionally low noise and wide dynamic range. Powered by the Manley Power supply, the Reference Gold provides pristine output with extended headroom and minimal distortion across the full audio spectrum. This combination of tube amplification and premium capsule technology yields an open, transparent, and dimensionally accurate representation of any vocal or acoustic source.
