UNIDIRECTIONAL CONDENSER

BOUNDARY MICROPHONE

- Designed for surface-mount

applications such as high-quality

sound reinforcement, professional

recording, television, conferencing

and other demanding sound

pickup situations.

- UniGuardTM RFI-shielding

technology offers outstanding

rejection of radio frequency

interference(RFI).

- Superior off-axis rejection for

maximum gain before feedback.

- Small-diameter UniPoint capsule near boundary eliminates phase

distortion and delivers clear, high-output performance.

- Heavy die-cast case and non-silp silicon foam bottom pads

minimize coupling of surface vibration to the microphone.

- Low-prole design with low-reectance nish for minimum visibility.

- AT871UG has contained electronics eliminate need for external

power module.

- The AT871UG requires 9V to 52V phantom power for operation

only.

Supplied as a cardioid, AT871UG accepts interchangeable elements

to permit selection of angle of acceptance from 100 to 360° °.

Positioning a properly designed miniature cardioid microphone

centrally on a large, at, unobstructed surface yields several distinct

advantages. Directionality is increased by 3dB, promoting enhanced

gain before feedback and further suppression of ambient noise.

Sensitivity is increased for improved signal to noise ratio. Phase

distortion due to reflected sound energy from boundary itself is

eliminated.

The microphone should be placed on a at,

unobstructed mounting surface, with the

front of the microphone facing the sound

source. The sound source should not be

below, or high than 60 above, the plane of °

the mounting surface.

Output from 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.

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

temperatures exceed 43 C for extended periods. Extremely high °

humidity should also be avoided.
