C98 series of paging gooseneck microphones

A range of paging microphones designed for use where voice clarity is an essential requirement and offering both moving coil and electret capsules fitted to fully flexible or rigid goosenecks. In addition, the microphone head only is available for free mounting or suspension.

C98 series features

Moving Coil Capsule: With a polar diagram approximating to cardioid, the capsule has a substantially flat frequency response with an added 'presence' lift at 3KHz.

Electret Capsule: The polar diagram is unidirectional in characteristic and the frequency response extends beyond the speech band. The internal FET pre-amplifier requires a small DC voltage to operate.

Mounting Methods: A variety of other mechanical means of mounting can be offered as alternatives to the standard 10mm diameter threaded bush. For example, mating with 3 PIN XLR sockets, or flange mount.

Order Codes:
• C98 Moving coil microphone fitted to fully flexible 295mm gooseneck terminated with M10 mounting base/nuts/washer.
• C98/XLR Moving coil microphone fitted to fully flexible 295mm gooseneck terminated with 3 pin male XLR connector.
• C98/LEC Moving coil microphone fitted to fully flexible 280mm gooseneck and 120mm solid tube terminated with 3 pin male XLR.
• BS100 ‘Superblast’™ for close speech protection. Fits over head of C98 series and all Buddy and DPM Series.

For electret versions (/E) contact the sales office for further details.
