Audio Technica PRO 3x User manual

• Designed for close-up vocal and instrumental use
• Dependable long life and consistent high quality
• Two-stage ball-type screen reduces wind noise and “popping”
during close use
• Cardioid polar pattern reduces pickup of sounds from the sides
and rear, improving isolation of desired sound source
Output from the microphone’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. For a high-impedance
(Hi-Z) mic input, connect a Low-Z balanced cable to a Hi-Z match-
ing transformer (A-T CP8201 or equal) at the equipment input.
When using the PRO 3x in settings with a stage monitor speaker,
the speaker should be located 180° off axis (at the rear of
the microphone). This placement, in conjunction with the
microphone’s uniform cardioid pickup pattern, will virtually
eliminate the possibility of undesired audio feedback.
The high sensitivity of the PRO 3x assures useful output and an
excellent match to most input sources. In some cases, however,
an attenuator such as the Audio-Technica AT8202 may be
required between the microphone and preamplifier to avoid
overloading sensitive input stages.
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.
