Reference Cardioid

Tube Microphone

From Manley Labs:

The Reference Cardioid utilizes a center-fixed cardioid capsule featuring a 6-micron gold-sputtered diaphragm engineered to emulate the high-frequency resonance, proximity effect, and tonal balance of vintage European tube microphones. This capsule design delivers rich midrange presence with controlled high-frequency response, providing flattering vocal capture with minimal need for corrective equalization during tracking and mixing stages.

The Reference Cardioid's all-tube circuitry provides low-noise operation with 150 dB maximum SPL capability, accommodating sources from intimate vocals to high-level percussion and brass instruments. A switchable -10 dB pad enables tracking of elevated sound pressure levels without distortion. Manley Power® supply technology delivers high-voltage operation for extended headroom and low-noise output, requiring minimal gain from connected preamplifiers.

Each Reference Cardioid is hand-assembled and tested at Manley's Chino, California facility using carefully selected vacuum tubes and components throughout the signal path. The microphone includes professional shock mount, protective carrying case, and genuine leather capsule cover for transport and storage. This combination of proven tube topology and meticulous assembly provides consistent performance for demanding professional recording applications.
