Audio-Technica ATM450 プリント

• Unique side-address stick design maximizes placement options 

with minimal obstructions

• Uncompromising sound quality for overheads, percussion, 

acoustic guitar, strings and other acoustic instruments 

• Integral 80 Hz HPF switch and 10 dB pad 

• Durable performance for professional applications

• Cardioid polar pattern reduces pickup of sounds from the sides 

and rear, improving isolation of desired sound source 

• Rugged, all-metal design and construction for years of trouble-free 

use

• Includes isolation clamp for shock protection, secure mounting and 

easy positioning

The ATM450 is intended for use in professional applications where
remote power is available. It requires 11V to 52V DC phantom
power, which may be provided by a mixer or console, or by a 
separate, in-line source such as the Audio-Technica AT8801 single-
channel or CP8506 four-channel phantom power supplies.

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.

An integral 80 Hz hi-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position reduces
the pickup of low-frequency ambient noise (such as traffic, air-
handling systems, etc.), room reverberation and mechanically-
coupled vibrations.

The ATM450 is also equipped with a switchable 10 dB pad that 
lowers the microphone's sensitivity, thus providing higher SPL 
capability for flexible use with a wide range of performers and 
system configurations.

The ATM450 includes an AT8471 isolation clamp to provide secure
mounting, versatile positioning and effective dampening of unwanted
mechanical noise.

Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 110° F (43° C) for extended per iods.
Extremely high humidity should also be avoided.
