Description
The ATM450 is a fixed-charge condenser microphone with a cardioid
polar pattern. It is designed specifically for use on overheads, percussion,
acoustic guitar, strings and other acoustic instruments in professional
live-sound and studio applications.
The ATM450 is a fixed-charge condenser microphone with a cardioid
polar pattern. It is designed specifically 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 flat response or low-frequency roll-off (via integral
80 Hz high-pass filter).

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.

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 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.
To engage the high-pass filter, 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 flexible use with a wide range of users and system configurations.

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.
