DPA Microphones APE40RS Acoustic Pressure Equalizer

Enhance Your Microphone’s Clarity with Acoustic Precision
The DPA APE40RS Acoustic Pressure Equalizer is a 40mm ball attachment engineered to refine the frequency response of DPA’s 4006A and 4006C microphones. By modifying on-axis and off-axis response, this passive acoustic processor enhances vocal and instrument recordings, providing greater presence, intelligibility, and tonal accuracy. Whether used in orchestral settings, studio recordings, or live performances, the APE40RS ensures superior sound fidelity with improved spatial clarity.

Upper-Midrange and High-Frequency Boost for Greater Presence
The APE40RS introduces a controlled upper-midrange and high-frequency boost without affecting low-end response. This adjustment enhances the clarity of vocals and instruments, making them more pronounced in dense mixes or reverberant environments. For speech, this presence boost improves intelligibility, ensuring crisp articulation in live broadcasts, lectures, and professional recordings.

Increased Directionality for Focused Sound Capture
This acoustic pressure equalizer enhances the directionality of the microphone at higher frequencies, focusing the sound capture while reducing off-axis interference. By minimizing unwanted reflections and ambient noise, the APE40RS is particularly useful in acoustically challenging environments, such as concert halls, churches, and outdoor performances.

Designed for Use with Omnidirectional Microphones
Omnidirectional pressure microphones benefit significantly from the APE40RS due to its precision diffraction technology. By controlling the acoustic environment surrounding the diaphragm, this equalizer adjusts the spectral response to optimize the microphone’s natural pickup pattern, creating a more balanced and refined sound profile.

Achieve Vintage Tonal Characteristics in Modern Recordings
For engineers aiming to recreate the warmth and coloration of legendary vintage microphones, the APE40RS provides an easy-to-use solution. By shaping the frequency response, it allows users to capture rich, detailed recordings that closely resemble the tonal signature of classic studio microphones, enhancing the depth and character of musical performances.

Compatible with DPA and Legacy Microphones
The APE40RS is fully compatible with the modular DPA 4006A and 4006C microphones, as well as legacy models such as the 4003, 4006, and 4006-TL. It serves as a modern replacement for the discontinued L30B accessory, ensuring seamless integration into existing microphone setups without sacrificing quality or performance.
