CardioidJoemeek JM47a

Cardioid Condenser Microphone

The JM47 is a fixed-cardioid, large-diaphragm FET condenser mic with a switchable 10dB pad and high pass filter.

JM47 PCB, circa 2000It was reportedly designed by Ted Fletcher, although its similarity to the MXL 2001/V67 circuit raises questions about its origin. Regardless of source, it was manufactured in China, and sold by Joemeek with an MSRP of $599.99.

We have come to realize that the great secret to producing superb sounds with depth and life, as so easily achieved in the 60’s and 70’s, is by using an audio balancing transformer output and as little electronics between the capsule and the transformer, to minimize the loss of subtleties and maximize sound depth.

Original JM-47, circa 2001The original model is easily distinguished from subsequent versions by its tapered body style. Since PMI’s acquisition of the Joemeek product line in 2003, and subsequent re-introduction of the JM47 in 2004, the JM47 has been built into a cylindrical body.

Alan Hyatt of PMI has described the JM47 as “a clone of the [MXL] V67 only with a pad and filter out of the Feilo factory where the V67 came from originally.”

The Joemeek JM47a is also known as: JM47, JM-47.

The mic was released in 1999.
