While a modern condenser microphone is not unduly sensitive to the environment, temperature extremes can be harmful. Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for long periods of time. Extremely high humidity should also be avoided.

ARCHITECTS AND ENGINEERS SPECIFICATIONS

The microphone shall be a fixed-charge condenser designed for suspended installation in permanent applications. It shall have a frequency response of 30 Hz to 20,000 Hz and a cardioid polar pattern with uniform 120° angle of acceptance. It shall be capable of accepting optional interchangeable elements for additional polar patterns. It shall be capable of handling sound input levels up to 128 dB with a dynamic range of 102 dB. Nominal open-circuit output voltage shall be 10.0 mV at 1 kHz, 1 Pascal. Output shall be low impedance balanced (200 ohms).

The microphone shall operate from an external 11V to 52V DC phantom power source. It shall offer outstanding rejection of radio frequency interference (RFI). The microphone shall be RoHS compliant.

The microphone shall have a permanently attached 50' (15.2 m) miniature low-noise cable. Its free end shall connect to a provided plate power module via a TA3F-type connector. An optional crimping tool and crimp sleeves shall allow for shortening of the cable without loss of RFI immunity.

The plate power module shall be designed to mount over a standard single gang metal electrical box for ceiling or wall mounting. The power module shall be provided with a switch for low-frequency roll-off. The low-frequency roll-off shall be a tailored roll-off at 80 Hz to minimize pickup of unwanted mechanical noise. In addition, the power module shall incorporate a switchable +10 dB gain setting. The power module face plate shall be semi-gloss white and mounting screws shall be included.

Output connections on the power module shall be screw terminals.

For suspended installations, the microphone shall be provided with an adjustable steel wire hanger. The steel wire hanger shall attach to the microphone body and allow for the positioning of the microphone without the need for tools. Microphones using goosenecks or other methods for positioning shall be unacceptable. A snap-on foam windscreen shall be provided.

The microphone shall be 1.08" (27.5 mm) long with a head diameter of 0.33" (8.4 mm). The microphone weight shall be 0.2 oz (5.5 grams) without cable. The microphone case, cable and steel hanger shall be finished in black [white].
