•    Natural sound and high isolation
    •    Superior gain-before-feedback
    •    Flexible and easy mounting
    •    Mount has no impact on acoustic sound
Perfect for PA amplification and live recording of a cello, the 4099C offers a sound that is considerably more natural than an internal microphone or pick-up as well as several excellent placement possibilities.
The 4099C is a unique clip microphone inheriting the sonic approach from the legendary DPA studio microphones to a new instrument microphone. The 4099C microphone and mounting system is meticulously designed and optimized for the violoncello. This is to ensure the best possible mount and audio reinforcement is achieved when performing live. The 4099C attaches to the C and A string below the bridge and allows for microphone capsule placement in the sweet spot between bridge and fingerboard, offering a unique combination of natural string sound and high audio separation on stage.
Representing years of research and development, the 4099 condenser microphones feature supercardioid polar patterns for superior gain-before-feedback. Fully capable of handling the cello’s dynamic range and subtle details, these microphones live up to their pedigree with sound as accurate as DPA’s other world-class microphones.
Despite its tiny, discreet size and elegant, lightweight design, the 4099C is extremely rugged. The versatile gooseneck provides stable and repeatable positioning. The mics can be easily unclipped and repositioned or moved to another instrument, while the mounting system is designed never to mar or scratch the finish of your instrument nor changing the sonic character of it.
Through the use of our extensive adapter system, the 4099 can be used as a standard 48V phantom powered microphone via the included XLR connector and is also compatible with virtually any wireless system.
Fleet owners of 4099s will appreciate the multiplicity of using the microphone for a number of different instruments simply by moving the microphone/gooseneck part to another instrument clip from the range.
With its very flexible design for a wide variety of mounting and positioning possibilities along with its extremely natural sound, the 4099 is truly a musician’s mic without equal. Continuing DPA’s heritage of sonic excellence, this series of microphones achieves the purest reproduction of your instrument and therefore your full range of expression.
