Architects and Engineers Specifications

The microphone shall be of the condenser type with a capsule and powering module assembly no larger than 0.75 in. (19 mm) in diameter. For applications requiring field switchable patterns, the capsule shall be demountable and attached by means of a half-turn bayonet action. (Threaded capsules shall not be allowed under this specification, because of inconvenience and the chance of cross- threading.) The microphone shall accept phantom powering over the nominal ranges of 12 to 48 volts and the nominal output impedance shall be equal to or less than 200 ohms at 1 kHz. The microphone shall provide a switchable 10 dB pre-electronics pad for operation at high sound pressure levels, and a switchable low-

frequency cut of 12 dB-per-octave shall be provided.

The polar pattern shall be (*), and on-axis frequency response shall be (*). Microphone sensitivity shall be at least (*) millivolts per pascal, and the self noise floor shall be no higher than (*) dB-A. The 1.0 % THD operating level shall be (*) dB SPL. (Additional for C 397-CVR)

The microphone capsule shall be separated from the powering/ output module by a thin gooseneck extension at least 20 in. (500 mm) in length. The microphone shall be the AKG Acoustics Model SE 300 B plus the (*) capsule.
