All use condenser capsules; both cardioid and omnidirectional patterns, within the hemisphere above the microphone, are offered. Most require phantom power, but battery only and battery or phantom-powered designs are included. All types have low-impedance, balanced outputs unless otherwise stated. PRO42 The PRO42 is a miniature condenser microphone with a hemi-cardioid half-space cardioid polar pattern, designed for surface-mounted applications in sound reinforcement and other demanding sound pick-up situations.

To install the battery, remove the cap from the top of the power module. Insert a fresh 1. For longest battery life, the switch should remain off except when the microphone is in use. Alkaline batteries are recommended for longest life. Remove the battery during long-term storage.
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. The microphone should be placed on a flat, unobstructed mounting surface. The sound source should not be below the plane of the mounting surface. The roll-off position reduces the pickup of low-frequency ambient noise such as traffic, air-handling systems, etc.
To engage the UniSteep the switch toward the "bent" line. Extremely high humidity should also be avoided. Note: Placing any object on a surface such as a conference table before its finish is fully cured may result in damage to the finish. It shall have an omnidirectional polar pattern in the hemisphere above the mounting surface and a frequency response of 30 Hz to 20, Hz.
The microphone shall operate from an external 11V to 52V DC phantom power source or, alternatively, from a 1. It shall be capable of handling sound input levels up to dB phantom or dB battery with a dynamic range of dB phantom or dB battery. Nominal open-circuit output voltage shall be Output shall be low impedance balanced ohms — phantom, ohms — battery. It shall offer outstanding rejection of radio frequency interference RFI. The microphone shall have a 7.
The output connector shall connect to a TB3M- type jack on the included power module. The power module shall house filter. The output of the power module shall be a 3-pin XLRM-type connector. The microphone shall have a diameter of Weight shall be 78 grams 2.
The microphone shall be housed in a die-cast case with a perforated steel grille. Finish shall be low-reflectance black. The microphone shall include a power module, a battery and a soft protective pouch. The Audio-Technica UA is specified.
