PRO 44

Cardioid Condenser Boundary Microphone

Features

•Wide-range condenser element with low-mass diaphragm for superior performance

•Uniform cardioid polar pattern for maximum rejection of unwanted sounds

•Self-contained electronics eliminate need for external power module

•Rugged design and construction for reliable performance

•Low-profiledesign for minimum visibility

Description

The PRO 44 is a wide-range miniature condenser microphone with a cardioid polar pattern. It is designed for surface-mount applications such as high-quality sound reinforcement and other demanding sound pickup situations.

The microphone requires 9V to 52V phantom power for operation.

The microphone's cardioid polar pattern provides a 120° angle of acceptance (cardioid in hemisphere above mounting surface).

The microphone includes a 7.6 m (25') output cable terminating in TA3F- type and XLRM-type connectors.

The microphone’s rubber non-slip bottom pad minimizes mechanical coupling of surface vibration to the microphone. The microphone is enclosed in a rugged housing with a black finish.

Installation and Operation

The PRO 44 requires 9V 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.

mounting surface.

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