• Premier Pro Series vocal microphone delivers excellent gain
before feedback and outstanding stage presence
• Hi-ENERGY
®
neodymium magnet for improved output and
transient response
• Extended frequency response for optimal vocal reproduction
• Two-stage ball-type screen reduces wind noise and “popping”
during close use
• Corrosion-resistant contacts from gold-plated XLRM-type
connectors
• Superior internal shock mounting reduces handling noise
• Rugged design and construction for reliable performance
• Hypercardioid 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 Lo-Z balanced cable to a Hi-Z matching
transformer (A-T CP8201 or equal) at the equipment input.
When using the PRO 61 in settings with a stage monitor speaker,
the speaker should be located 135° off axis (45° off the rear of the
microphone). This placement, in conjunction with the microphone’s
uniform hypercardioid pickup pattern, will virtually eliminate the
possibility of undesired audio feedback.
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.
