• High gain-before-feedback
• Flat frequency response
• Compact, discrete size
• Excellent phase characteristic

4099P is a piano miking solution that makes it easy to achieve a high level of isolation on stage while providing clean and transparent stereo sound quality with realistic dynamics.

The 4099P is a complete system which includes a pair of sensitivity matched 4099 microphones on goosenecks with magnetic mounts to allow the most realistic capture of a piano.  With its low profile and unobtrusive design it is perfect in closed lid scenarios for capturing true acoustic piano sound in a live setting.

The versatile magnet mount/gooseneck system provides stable and repeatable positioning. The mics can easily be positioned at different angles via the flexible gooseneck to provide a variety of sound nuances. The system includes two 3-pin XLR adapters.

The mounts can also be used with various instruments with magnetic surfaces.

The package includes
Two sensitivity selected supercardioid 4099 gooseneck mics
Integrated windscreen and shock mount system
Magnet mounts to place on piano frame
Two DAD6001 3-pin XLR adapters
