Dynamic Harmonica and Instrument Microphone for High SPL Sources
The Audix FireBall is a dynamic instrument microphone built for musicians who need tight control and clarity when capturing loud acoustic sources. Designed to handle sound pressure levels up to 140 dB without distortion, it delivers focused, reliable performance for harmonica, beatbox, percussion, and high-output wind instruments in live sound and recording environments.
Designed for Close-Miking and Handheld Performance
The FireBall features a compact, round handheld design that supports traditional cupping techniques commonly used by harmonica players. This form factor allows performers to control tone and dynamics naturally while maintaining consistent microphone placement, making it especially effective for expressive, close-range playing styles.
Cardioid Pickup Pattern for Feedback Control
A tight cardioid polar pattern minimizes off-axis sound and ambient noise, helping reduce feedback on loud stages. This focused pickup makes the FireBall well suited for use near monitors and other instruments, delivering a clean signal that stays present in dense live mixes.
Clear Frequency Response for Musical Detail
With a frequency response of 50 Hz to 16 kHz, the FireBall captures detailed midrange articulation and crisp highs while reducing unwanted low-frequency rumble. This voicing works well not only for harmonica, but also for accordion, saxophone, trombone, brass, woodwinds, and select vocal applications.
Built to Withstand Stage and Touring Use
The precision-machined aluminum body provides durability for frequent gigging and touring. Its solid construction ensures consistent performance night after night, making it a dependable choice for musicians who need rugged gear that performs under demanding conditions.
Versatile Tool for Live Sound and Studio Use
While optimized for live performance, the FireBall also performs well in studio settings where isolation and control are important. Its ability to manage high SPL sources without distortion makes it a practical option for recording aggressive or percussive instruments with confidence.
