Overview

The 4006 Omni Mic 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 linear frequency response from 10 to 20 kHz (±2 dB).

This mic is linear and true in character. It has earned its status as a worldwide recording standard and is our most popular pencil mic. 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

4006A Omni Mic

This is a very 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.

A wide 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. Furthermore, these accessories will not produce any phase shift, noise or distortion that would otherwise be introduced by an electrical filter. These accessories are available in the Stereo Kits and Surround Kits.
