Coles Electroacoustics 4038 Studio Ribbon Microphone with Rigid Mic Mount, 30 to 15000Hz Frequency Response, 300Ohms Impedance, -65dB Sensitivity

The Coles Electroacoustics 4038 Studio Ribbon Microphone is of British Broadcasting design (BBC) and used for broadcasting and recording such sounds where a clear smooth wide range frequency response, absent of transient distortion and relatively high sensitivity is essential. It has a proven reliable performance capability, being since its introduction, used by broadcasting networks throughout the world such as the BBC. The frequency response is exceptionally flat from 30 to 15,000 c/s and throughout this range the shape of the bi-directional (figure of eight) polar response is maintained substantially constant both in the horizontal and vertical planes, giving a natural smooth sonic quality textured response to sound signal being picked up. Comes in a foam lined rigid plastic carrying case with 4069 jack plug, and soft cloth protective bag, for safe keeping.

Ribbon
Low mass damped ribbon to control transient response

Magnetic Fields
By use of hum neutralizing wiring and magnetic shielding of the toroidal ribbon to line transformer 30 to 40dB reduction is achieved in response to stray disturbing magnetic fields.

Body Housing
Made of heavy gauge perforated brass backed by finely woven monel mesh. Rotating hinge connection allows microphone to tilt through 90 degree and turned in any direction when either suspended or free standing.
