d:dicate 3506A is a complete 4006A stereo kit with two carefully factory-matched phantom powered omni condensers. The 4006A's are matched within +/-0.5 dB on both frequency range and sensitivity in the microphone's entire frequency bandwidth. With the 4006A, engineers, broadcasters and musicians alike can achieve extremely clean, natural and precise reproduction in a variety of applications. Ideal for A-B stereo pairs for symphonic concert hall recordings, the 4006A also excels on vocals and for close-miking instruments like grand piano, guitar, double bass and percussion.

The high sensitivity, low noise-floor and extremely linear frequency response of the microphone pair makes the 3506A the perfect choice for all professional A-B stereo recordings.

Several tools in one: a selection of acoustic modification accessories, including interchangeable protection grids and acoustic pressure equalizers, allows the 4006A's to be acoustically transformed into different microphone versions, making it the most multifaceted mic in your collection and a tremendous value.

By simply changing a grid or adding a ball, it is possible to gain several unique frequency responses and directional characteristics from a single mic. Furthermore, these grids and elements will not produce any phase shift, noise or distortion that would otherwise be introduced by an electrical filter.
