The PRO 31 was designed by Audio Technica specifically for close-up vocal use. This a high-output microphone, meant to capture all the subtle nuances of a vocal performances; nuances that many other microphones in this price range neglect. Since the PRO 31 is meant for close miking, major concerns to Audio Technica during the design phase were breath noise and popping. These issues were resolved by involving a two-stage screen, which helps to eliminate these unwanted types of sounds immensely. The PRO 31 also features a silent on/off Magnalock designed switch.
- Designed for close-up vocal use
- Silent on-off operation thanks to MagnaLock™ switch design
- Hi-ENERGY® neodymium magnet for improved output and
transient response
- Two-stage ball-type screen reduces wind noise and “popping”
during close use
- Corrosion-resistant contacts from gold-plated XLRM-type
connectors
- Rugged design and construction for reliable performance
- 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.
