DPA Microphones APE50RS Acoustic Pressure Equalizer

Enhance Your Microphone’s Frequency Response for Superior Clarity
The DPA APE50RS Acoustic Pressure Equalizer is a 50mm ball attachment designed to refine the on-axis and off-axis frequency response of DPA’s 4006A and 4006C microphones. This passive acoustic processor enhances the presence, clarity, and spatial definition of recorded sound, making it ideal for a variety of recording applications. Whether used in orchestral performances, studio sessions, or live broadcasts, the APE50RS ensures optimal sound reproduction with increased focus and tonal accuracy.

Upper-Midrange Boost for Greater Vocal and Instrument Presence
The APE50RS introduces a controlled upper-midrange and high-frequency boost while maintaining a stable low-end response. This enhancement increases the intelligibility of vocals and the clarity of instruments, making them stand out in complex mixes. It is particularly useful in environments where speech or musical detail must be accentuated, such as live performances, studio recordings, and broadcast productions.

Increased Directionality for Focused Sound Capture
By modifying the microphone’s spectral response, the APE50RS enhances directionality at higher frequencies. This adjustment helps focus the microphone’s pickup pattern, reducing ambient noise and unwanted reflections. As a result, recordings achieve a more precise, detailed sound that maintains depth and spatial accuracy, even in challenging acoustic environments.

Optimized for Use with Omnidirectional Microphones
Designed specifically for omnidirectional pressure microphones, the APE50RS utilizes diffraction techniques to shape the sound field around the microphone diaphragm. This technology ensures a well-balanced frequency response, improving the natural tonal characteristics of the microphone without introducing unwanted coloration.

Recreate the Warmth of Vintage Microphones
For audio engineers and producers seeking to capture the distinct tonal qualities of vintage microphones, the APE50RS provides a practical and effective solution. By shaping the microphone’s frequency response, it recreates the warmth and presence associated with classic recording equipment, making it an invaluable tool for music production and sound design.

Seamless Compatibility with DPA and Legacy Microphones
The APE50RS is fully compatible with DPA’s modular 4006A and 4006C microphones, as well as legacy models including the 4003, 4006, and 4006-TL. It serves as a direct replacement for the discontinued L30B, offering modern performance while maintaining compatibility with classic microphone setups.
