AKG Blue Line Series
Condenser Microphones
Description
The AKG Blue Line Series consists of a family of directional
prepolarized condenser capsules and microphone configurations
that are all compatible with a single powering/output assembly.
Because of the general popularity of the cardioid pattern, the
CK 91 cardioid capsule and SE 300 B powering/output assembly
are sold as a single unit, the AKG Model C 391 B microphone.
The remaining Blue Line capsules offer the following patterns:
CK 92 (omnidirectional), CK 93 (hypercardioid), CK 94
(bidirectional), and CK 98 (shotgun capsule, high directivity).
Three additional configurations are available: CK 97-O
(omnidirectional lavalier), CK 97-C (cardioid lavalier), CK 97-CVR
(cardioid gooseneck with bass roll-off). The Blue Line Series is
suitable for studio, live sound, and a variety of speech
reinforcement applications, where the facility for switching
capsules is a major advantage. The positive Modulock™
bayonet design allows these changes to be made quickly. The
Blue Line microphones exhibit accurate axial response and
uniform pattern control. Self noise and maximum operating
levels are exemplary, creating a very wide usable dynamic range
for the most demanding operations. The SE 300 B powering/
output assembly provides for 10 dB of attenuation for operation
at high sound pressure levels, as well as a 12 dB/octave low cut
below 75 Hz for close usage. A complete line of optional
accessories is available including an extension cable for
operating the microphone capsule up to 10 ft. (3 meters) from
the powering/output module.
