The DPA 4288 brings studio-grade directional capture to demanding theatrical, broadcast, and corporate AV environments where intelligibility and off-axis rejection are critical. Its 4088 CORE+ directional capsule delivers cardioid pattern control with exceptionally low self-noise—26 dB(A) typical—allowing front-of-house engineers to push gain without hiss while maintaining natural tonal balance across the entire vocal range.

Built for integrators and production teams managing high-output vocalists and presenters, the 4288 handles up to 147 dB SPL peak without distortion, accommodating both soft speech and full-voice singing without gain structure compromise. The flexible single-ear mount adapts to left or right positioning, and its lightweight profile—just 10 grams—reduces fatigue during extended wear in multi-hour productions. IP58 environmental protection resists perspiration and humidity, ensuring consistent RF performance in demanding touring and installed applications.

The convertible adapter system terminates in TA4F Mini-XLR for direct wireless bodypack integration, eliminating the need for custom cabling or third-party adapters. Engineers working across multiple wireless platforms benefit from DPA's modular adapter ecosystem, allowing rapid reconfiguration between rental inventory and installed systems without sacrificing capsule performance or frequency response consistency.
