The 4038MP from Coles is a matched pair of studio ribbon microphones that were 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 bidirectional (figure 8) polar pattern provides a uniform pickup response at either side of the diaphragm. The bidirectional pattern proves valuable when capturing mult
