AKG 451E Cardioid Pencil Condensor Microphone
The AKG C-451E is a Condenser Microphone System using audio frequency circuitry with Field Effect Transistors.
Low noise level, extremely high reliability and life-long stability are inherent features of the C-451E.
Low current consumption at low voltage and Phantom circuit powering permits feeding the microphone supply voltage via a standard two-conductor plus shield audio cable.
In addition to the central feeding technique, directly off the DC supply of the associated amplifier, the microphone may be powered by the AKG N-46E AC power supply or the AKG B-46E DC battery supply.
The basic C-451E system consists of the C-45IE preamplifier, CK-l miniaturized cardioid condenser microphone capsule, stand adapter and windscreen.
The C-451E offers interchangeable capsules, allowing the selection of different response characteristics to adapt the microphone to various types of environments and re cording applications.
Its highest professional reproduction qualities makes it eminently suitable for recording studios, television and radio broadcast, motion picture studios, stage and concert hall applications as well as high quality commercial sound installations.
