The Coles 4038 studio ribbon microphone was originally developed by the BBC as a broadcast microphone. Recognized for its wide, flat frequency response and high sensitivity, the 4038 quickly became a valuable tool in the recording studio as well as broadcast applications. The pressure gradient ribbon transducer is capable of withstanding high sound pressure levels without distortion and the bi-directional (figure 8) polar pattern provides a uniform pick up response at either side of the diaphragm. The bi-directional pattern proves valuable when capturing multiple singers, musical instruments, ambiance capturing and more. The smooth, rich sonic detail of the 4038 has the made the microphone a classic among some of the recording industries most celebrated engineers.
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 to 20,000 Hz 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.
