Audio-Technica ATM250 Dépliant

• 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
mater ial in the windscreen's mesh surface, can degrade 
performance.
