CARDIOID CONDENSER INSTRUMENT MICROPHONE

- 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-matal 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 required 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

AT8506 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 80Hz 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 trafc,

air-handling systems, etc.), room reverberation and mechanically

coupled vibrations.

The ATM450 is also equipped with a switchable 10 dB pad that

lowers the microphones’s sensitivity, thus providing higher SPL

capability for exible use with a wide range of performers and system

congurations.

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 40°C for extended periods. Extremely high

humidity should also be avoided.
