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.
