Hypercardioid Dynamic Mic. Hypercardioid Dynamic Instrument Microphone A natural in high-SPL applications, the PRO 25ax is tailored for kick drum, percussion, brass, and other highly dynamic instruments. It delivers a warm low-frequency response with excellent presence. Its hypercardioid polar pattern improves isolation of the sound source, delivering superior off-axis rejection for maximum gain before feedback. The included isolation clamp offers versatile mounting options and effective dampening of mechanical noise.
