ATM250
HYPERCARDIOID DYNAMIC
INSTRUMENT MICROPHONE
• Frequency response tailored for kick drum, percussion, brass, and
other highly dynamic instruments
• Handles very high SPL at close range
• Big, warm low-frequency response with excellent presence
• Hypercardioid polar pattern reduces pickup of sounds from the
sides and rear, improving isolation of desired sound source
• Durable performance for professional applications
• Hi-ENERGY
®
neodymium magnet for improved output and
transient response
• Superior off-axis rejection for maximum gain before feedback
• Corrosion-resistant contacts from gold-plated XLRM-type
connector
• Rugged, all-metal design and construction for years of trouble-free
use
• Includes isolation clamp for shock protection, secure mounting and
easy positioning
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.
The ATM250 includes an AT8471 isolation clamp to provide secure
mounting, versatile positioning and effective dampening of
unwanted mechanical noise.
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.
