The Coles 4038 Studio Ribbon Microphone is a British Broadcasting (BBC) design for broadcasting and recording applications. It is used where a clear smooth wide range frequency response, absence of transient distortion and relatively high sensitivity is essential. The 4038 is a proven performer, and is in use around the world by broadcasting networks such as the BBC as well as top engineers and studios on hit recordings.
Frequency response of the 4038 is exceptionally flat from 30 Hz to 15 kHz 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 sonic quality with smooth frequency response.
Each microphone comes in a foam lined rigid plastic carrying case with 4071B three-pin signal to XLR adapter, and a soft cloth protective bag for safe keeping. Also included is the rigid microphone stand adapter for mounting on standard 5/8" mic stands.
Low mass damped ribbon to control transient response
Substantially flat frequency response from 30 to 15,000 c/s
Magnetic Fields: By use of hum neutralizing wiring and magnetic shielding of the toroidal ribbon to line transformer 30 to 40 dB reduction is achieved in response to stray disturbing magnetic fields
Extremely low (non-linear) distortion
Exceptionally low hum pick-up
Bi-directional (figure of eight) polar curve shape accurately maintained in both horizontal and vertical planes
