Description
DPA 4088-F Headband Microphone is a miniature cardioid headband built on the finest DPA experiences in microphone design and manufacturing, providing the best sounding directional headworn microphone.
Sound quality, visual elegance and versatility go hand in hand to transform every show into the performance of a lifetime.
The capsule is a pre-polarized first order pressure gradient transducer, hidden in a small and lightweight housing with dimensions just slightly larger than our omni capsules.
DPA 4088-F Headband Microphone is a Winner of the coveted PAR Excellence Award 2005 for innovation, value and performance.
