The DPA 4091 is a professional, highly sensitive omnidirectional condenser microphone designed for capturing vocals, instruments, and ambiance in the professional recording and sound reinforcement. The ultra-sensitive miniature omnidirectional capsule reproduces audio in pristine detail without noise or distortion. The contoured frequency response makes the 4091 a prime choice for guitar, piano, drum overheads or sound reinforcement measuring.

Low Sensitivity
The low sensitivity transducer handles up to 144dB SPL. The result is plenty of headroom for loud sound sources such as guitar and bass cabinets.
Omnidirectional Polar Pattern
The omnidirectional polar pattern reproduces at an even, uniform polar pattern. The pattern is ideal for ambiance and measurement applications.
Wide Frequency Response
The wide frequency response results in rich detail and accurate audio reproduction.

Note: All DPA microphones feature a MicroDot connection and require an optional adapter for use with various wireless microphone transmitters unless a pigtail mic was purchased.
