• Ideal for kick drum, percussion, brass, and other highly dynamic
instruments
• Excels in high-SPL applications
• Warm low-frequency response with excellent presence
• Superior off-axis rejection for maximum gain before feedback
• Versatile mounting options and effective dampening of
mechanical noise thanks to included AT8471 isolation clamp
• Corrosion-resistant contacts from gold-plated XLRM-type
connector
• Rugged design and construction for reliable performance
• Hypercardioid polar pattern improves isolation of desired sound

impedance (Lo-Z) balanced. The signal appears across Pins 2 and
3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”– positive
acoustic pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables must be
wired consistently: Pin 1-to-Pin 1, etc.
The PRO 25ax includes an AT8471 isolation clamp to provide
secure mounting, versatile positioning, and effective dampening of
unwanted mechanical noise.
Take care to keep foreign particles from entering the windscreen.
An accumulation of iron or steel filings on the diaphragm, and/or
foreign material in the windscreen’s mesh surface, can degrade
performance.
