Manley Laboratories, Inc Reference Cardioid
Cardioid Tube Condenser Microphone
The Manley Reference Cardioid is a premium tube condenser microphone, built by Manley Labs in Chino, CA. It uses a tube-and-transformer topology and a large-diaphragm capsule.
Only the front membrane is metallized; the rear half of the capsule has a clear membrane, as do most single-pattern K67 capsules; this is required for Cardioid pattern control.
The capsule in the Reference Cardioid differs from the one in the Reference Gold; this is one of the primary component differences between the two mics. The Gold uses a CK12-style, dual-diaphragm capsule manufactured for Manley by Josephson Engineering.
The Reference Cardioid capsule is manufactured by Feilo, then subjected to selection and testing in the US.
The tube, as of 2011, is a low-noise 12AT7. In its history, the Reference Cardioid (and Reference Gold) have been built with other tubes, depending on availability:
We originally used 6072A until it became impossible to find quiet ones out of the NOS dreck left on the market, then we used 12AX7 for awhile.)
The microphone’s output transformer was designed and is built in-house by Manley Labs staff.
Manley Labs’ test procedure includes comparison of every new mic against the original “reference” microphone to ensure consistency of performance.
The Reference Cardioid ships in a padded metal suitcase with its power supply and cables, a very slick compact swivel adapter, a leather dust cover for the top half of the microphone, and the mic’s integral shockmount (with spare elastics).
(Additional specs on this mic are forthcoming.)
