DPA d:dicate™ 4006A Omni Mic DPA

4006A OMNIDIRECTIONAL MICROPHONE

The d:dicate™ 4006A Omnidirectional Microphone is linear and true in character. It has earned its status as a worldwide recording standard and is the most popular mic in our d:dicate™ Series.
This highly sought after mic has forged its enviable reputation over the past quarter of a century by repeatedly exhibiting its total transparency in any recording situation.

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. The MMC4006C is also easier to position due to its smaller size.

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 available as a sensitivity-selected stereo pair ST4006A and surround kits 5006-11A and 5006A. The d:dicate™ 4006A replaces the non-modular legacy 4006 Omnidirectional Microphone.
