The DPA 4099 CORE+ Mic, for Bass Loud SPL, is a supercardioid clip-on condenser microphone specifically designed for double bass, offering 108dB of dynamic range, distortion-free performance up to 142dB SPL, and precision mounting for accurate live or studio capture.

Distortion-Free Audio with CORE+

Equipped with DPA’s latest CORE+ amplifier technology, the microphone eliminates harmonic distortion across the entire dynamic range. CORE+ pushes artefacts below the threshold of human perception, creating an uncoloured and highly detailed signal path. The result is full-range clarity, whether capturing delicate bowing or aggressive plucking, with a linear response from low to high SPL.

Dynamic Headroom for Demanding Environments

The Loud SPL variant of the 4099 CORE+ handles sound pressure levels up to 142dB before clipping and maintains a wide 108dB dynamic range. It captures the full expressive spectrum of the double bass without introducing compression, harshness, or artefacts, making it ideal for amplified and acoustic settings alike.

Natural Sound and High Isolation

The supercardioid capsule ensures focused pickup with strong rejection of surrounding instruments, allowing clean signal acquisition even in complex orchestral or ensemble environments. The microphone maintains tonal consistency both on and off axis, preserving the instrument’s acoustic identity with exceptional fidelity.

Specialised Mounting System

Designed for double bass, the rubber-coated clamp mounts securely beneath the bridge without damaging the instrument. Its adjustable gooseneck allows precise placement, ensuring repeatable and stable microphone positioning throughout performance or recording sessions.

Integrated Professional Features

The included DAD6001-BC XLR adapter provides 48V phantom power support and integrates a built-in high-pass filter to manage low-end rumble and handling noise. The system is also compatible with DPA wireless adapters for flexible setup in mobile or live applications.

Optimised for Stage and Studio Use

Purpose-built for demanding bass applications in both live and studio environments, the 4099 CORE+ delivers transparent, distortion-free audio, high SPL handling, and robust mounting — ensuring consistent, professional-grade results for sound engineers and performers.
