• Ideal for sax, toms, brass and percussion
• Excels in high-SPL applications
• Perfect for active stage performances
• Extended frequency response captures subtle nuances of the
performance
• UniMount
®
clip permits accurate positioning, provides shock
resistance and protects element
• Corrosion-resistant contacts from gold-plated XLRM-type
connector
• Cardioid polar pattern reduces pickup of sounds from the sides
and rear, improving isolation of desired sound source
The PRO 35ax is intended for use in professional applications
where remote power is available. It requires 11V to 52V DC
phantom power, which may be provided by a mixer or console, or
by a separate, in-line source such as the Audio-Technica AT8801
single-channel or CP8506 four-channel phantom power supplies.
An integral 80 Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position
reduces the pickup of low-frequency ambient noise (such as traffic,
air-handling systems, etc.), room reverberation and mechanically
coupled vibrations.
Output from the power module’s XLRM-type connector is low
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.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 110° F (43° C) for extended periods.
Extremely high humidity should also be avoided.
