for use in live performances, theatre presentations, entertainment and television reporting, sports casting, language interpretation,
houses of worship and many more vocal and music performance applications. The SP-746 is characterized by its waterproof, noisecancelling element, designed for use in dance and fitness instruction, aerobics, theme park and amusement games, or anywhere there

heavy-duty performance series headworn microphones are built extremely rugged to withstand the normal abuse associated with
performance applications. They are compatible with most wireless systems, or direct cable connections when incorporated with any
of Special Projects wide variety of connectors and/or power modules.
