Audio Technica PRO 35 Specifications

Polar Pattern 200 Hz LEGEND 5 kHz 1 kHz 8 kHz 12" or more on axis LEGEND Roll-off Frequency in Hertz Frequency Response Response in dB • 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 35 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.
