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.
