ATM450

Cardioid Condenser Instrument Microphone

Features

• Uncompromising sound quality for overheads, percussion,

acoustic guitar, strings and other acoustic instruments

• Unique side-address stick design maximizes placement options

with minimal obstructions

• 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

• Isolation clamp provides secure mounting, versatile positioning,

and effective dampening of unwanted mechanical noise

• Integral 80 Hz high-pass lter switch and 10 dB pad switch

Description

The ATM450 is a xed-charge condenser microphone with a cardioid

polar pattern. It is designed specically for use on overheads, percussion,

acoustic guitar, strings and other acoustic instruments in professional

live-sound and studio applications.

The microphone requires 11V to 52V phantom power for operation.

The cardioid polar pattern of the microphone is more sensitive to sound

originating directly in front of the element, making it useful for controlling

feedback and reducing pickup of unwanted sounds.

The output of the microphone is a 3-pin XLRM-type connector.

The microphone is equipped with a switchable 10 dB pad and a switch

that permits choice of at response or low-frequency roll-off (via integral

80 Hz high-pass lter).

The microphone is enclosed in a rugged housing. The included AT8471

isolation clamp permits mounting on any microphone stand with 5/8"-27

threads. A windscreen and a soft protective pouch are also included.

Operation and Maintenance

The ATM450 requires 11V to 52V phantom power for operation.

Output 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 high-pass lter provides easy switching from a at

frequency response to a low-end roll-off. The roll-off position reduces

the pickup of low-frequency ambient noise (such as trafc, air-handling

systems, etc.), room reverberation and mechanically coupled vibrations.

To engage the high-pass lter, use the end tip of a paperclip or other

small pointed instrument to slide the switch toward the “bent” line.

The microphone is also equipped with a switchable 10 dB pad that

lowers the microphone’s sensitivity, thus providing higher SPL capability

for exible use with a wide range of users and system congurations.

To engage the 10 dB pad, use the end tip of a paperclip or other small

pointed instrument to slide the switch toward the -10 position.

Avoid leaving the microphone in the open sun or in areas where

temperatures exceed 110° F (43° C) for extended periods. Extremely high

humidity should also be avoided.
