The 4030L from Coles is a studio ribbon, figure 8 polar pattern microphone manufactured using CNC machinery and magnet technology as used in the Coles 4040 and 4050 microphones. The frequency response of the 4030L is exceptionally flat, from 50 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.
The 4030L is a versatile microphone designed for critical recording applications. Its frequency response characteristics and ability to capture detail make it useful for many instruments. The 4030L can be used alone or as a pair with an optional stereo mount, which can be rotated through 360 degrees; for the popular "Blumlein" (crossed figure-of-eight) stereo configuration, or other configurations of choice. The red dot indicates the front of the mic for phasing purposes.
The 4030L microphone is delivered in a foam-lined rigid carrying case with an adjustable universal stand mount.
