AKG BLUE LINE SERIES MODULAR MICROPHONES

                         Impeccable performance and extraordinary flexibility set a
                         higher standard for moderately priced modular condenser
                         systems. Building on the foundation of AKG's
                         reference-standard C 451 system, the AKG Blue Line elevates
                         the state-of-the-art by offering higher sensitivity, lower noise,
                         better phase and frequency response linearity, and lower
                         distortion. At the heart of each AKG Blue Line capsule is an
                         active transducer incorporating an ultra-low mass,
                         gold-sputtered diaphragm element. Innovative design and
                         precision manufacturing techniques result in a transducer
                         offering extraordinarily flat response, balanced directional
                         characteristics, minimal sensitivity to handling noise, and
                         virtual immunity to electrically induced noise. AKG Blue Line's
                         HDSMD (High Density Surface Mount Device) electronics are
                         lighter, more compact, and more reliable than conventional
                         circuit designs. The universal SE 300 B powering and output
                         module features a switchable 12 dB/octave bass cut filter at 75
                         Hz to cut rumble, and a switchable ­10 dB pad for very high SPL
                         applications. Transformerless output electronics preserve the
                         fidelity of the capsules across the full audio bandwidth with
                         extremely low LF distortion. The AKG Blue Line System is also
                         uncommonly easy to use, thanks to the bayonet coupling.
                         Tactile and visual guides allow fast, accurate assembly even
                         under difficult field conditions with no possibility of
                         cross-threading. The bayonet system also features
                         self-cleaning contacts to maintain a clean signal, even after
                         years of outdoor use in hostile environments. 

                         AKG Blue Line SE 300 B Transformerless Powering/Output
                         Module is for use with all AKG Blue Line modular capsules, the
                         SE 300 B operates from any 9­52 V phantom power supply.
                         Incorporates three position switch offering linear response, ­10
                         dB preattenuation and 12 dB/octave 75 Hz bass-cut filter. Stand
                         adapter included. 

                         CK 91 provides a flat frequency response and uniform polar pattern of the CK
                         91 make it ideal for general applications where suppression of
                         off-axis sound is desired. Includes foam windscreen.
