DPA 3506A

Even though the standard tolerances on our d:dicate™ series are extremely low, a stereo match is even closer. These specially selected d:dicate™ 4006A microphones are matched within ±0.5 dB on both frequency response and sensitivity.

For reference stereo recording, there is no better choice than a d:dicate™ 4006A Microphone. These omnidirectional condenser microphones are linear and true in character. They come as a hand-matched pair that offers the truest capture of stereo sound available. The microphone capsule The MMC4006 Omnidirectional Microphone Capsule offers total transparency in any recording situation. It picks up incredible detail and depth of sound. The definition of its high-frequency characteristics across a wide range of instruments is impressive. It offers natural sound, high sensitivity, low noise-floor and extremely linear frequency response from 10 to 20 kHz (±2 dB).

The d:dicate™ 4006A Omnidirectional Microphone is a flexible solution. Engineers, broadcasters and musicians alike can achieve clean, natural and precise sound reproduction. This mic is ideal for A-B stereo pairs for symphonic concert hall recordings. It also excels on vocals, for close-miking all types of instruments and as an outdoor interview microphone.

A selection of accessories is available, including acoustic pressure equalizers, a nose cone and interchangeable protection grids. These accessories can acoustically transform the mic. By changing grids, it is possible to gain several unique frequency responses and directional characteristics from the mic. Furthermore, these accessories will not produce any phase shift, noise or distortion that would otherwise be introduced by an electrical filter. A truly flexible range The d:dicate™ 4006A Omnidirectional Microphone is part of the flexible d:dicate™ Microphones Series. It combines the MMC4006 Omnidirectional Capsule with the MMP-A preamplifier. This combination is for the true audiophile. It offers low distortion and totally accurate and faithful sound.

Another option, the d:dicate™ 4006C Omnidirectional Microphone, Compact offers a subtle character alteration with a bit more "body" to the low end than the d:dicate™ 4006A Omnidirectional Microphone.

At any time, and with no tools needed, it is possible to transform the d:dicate™ 4006A Omnidirectional Microphone into a new configuration. You can combine it with another d:dicate™ or d:facto™ Microphone Capsule or Preamplifier.

The d:dicate™ 4006A Omnidirectional Microphone is also available individually.
