Lawson Inc L47MP MKII
MSRP: $1,995 Multi-Pattern Condenser Tube Microphone
Description
The L47 is a recreation and reinterpretation of the Neumann U47. It is a continuously-variable multipattern tube condenser microphone with several interesting characteristics.
The pattern-selection switch on the power supply allows selection of an infinite number of pickup patterns. In Cardioid mode, the mic’s sensitivity is increased by 3dB and the noise floor is dropped by 3dB. Set to any other position, the mic is in “multipattern” mode, which is indicated by a blue LED within the mic’s headbasket.
The capsule in the L47fet was designed by Gene Lawson, and is based on the M7 capsule originally used in the U47/U48 microphones. Note that the M7 used a relatively thick PVC diaphragm, whereas Lawson’s capsule uses a very thin (3-micron) diaphragm mostly likely made of Mylar.
The amp circuit’s 6N1P tube is socketed in a high-end socket employing “heavily gold-plated beryllium copper contacts;” it promises low-noise operation and long tube life.
The output circuit uses a Lundahl transformer.
The Lawson Inc L47MP MKII is also known as: L47MP.
The mic was released in 1997.
