The DPA 4099 CORE+ Stereo System for Accordion Loud SPL is a matched pair of supercardioid clip-on condenser microphones specifically designed for accordion, delivering a dynamic range of 108dB, distortion-free performance up to 142dB SPL, and precise stereo imaging through CORE+ technology.

Distortion-Free Precision with CORE+

Utilising DPA’s advanced CORE+ amplifier technology, the system removes harmonic distortion across the full dynamic range. This refinement surpasses the original CORE specification by eliminating residual artefacts entirely, resulting in transparent sound capture with only system noise remaining. This distortion-free performance ensures clarity and neutrality even at extreme sound pressure levels, a critical requirement for live accordion performances or nuanced studio work.

Optimised Stereo Imaging and Tonal Clarity

The stereo configuration provides accurate left-right imaging, capturing the full harmonic range of both treble and bass sides of the instrument. Each supercardioid microphone offers high rejection of off-axis sources, enabling focused capture and excellent separation in ensemble or amplified settings. Tonal consistency is maintained on and off axis, free from harshness or midrange colouration.

High SPL Capability and Dynamic Headroom

Each mic in the kit handles up to 142dB SPL before clipping and maintains 108dB of usable dynamic range, ensuring the system performs reliably even under intense dynamic conditions. This allows engineers to capture both delicate textures and high-energy passages without loss of detail or introduction of artefacts.

Secure and Non-Invasive Mounting

The accordion-specific mounting system uses rubber-coated clips to securely fasten the goosenecks to either side of the instrument. This ensures stable, repeatable placement while protecting the instrument’s finish. The flexible gooseneck arms provide precise positioning and maintain alignment throughout performances.

Professional Integration and Compatibility

Each microphone connects via a DAD6001-BC XLR adapter, which supports 48V phantom power and includes a built-in high-pass filter to control low-frequency rumble. The system is also compatible with DPA wireless adapters, providing flexible options for mobile and live use.

Designed for Demanding Acoustic Environments

Purpose-built for professional accordion players in live, studio, and broadcast environments, the 4099 CORE+ Stereo System captures the instrument’s full acoustic range with pristine accuracy, high SPL resilience, and unmatched clarity, making it an essential tool for audio professionals working with complex acoustic instruments.
