The SM Series family brings Digital Hybrid Wireless® technology to miniature transmitters in several different configurations for essentially any wireless microphone application with a lavaliere microphone. The tiny size of the single battery SMa model makes concealment easy, yet with a full 100 mW output, it does not sacrifice performance. The dual battery SMDa model doubles the battery life of the SMa with the same feature set. The SMQa offers 250 mW RF output power to extend operating range and the unique RM provides hands-free remote control for all three models. Switching power supplies throughout the design allow long battery life with NiMH batteries.

Setup and control is simplified with membrane switches and an LCD interface. Multiple functions are clearly marked on the panel, with on-screen prompts on the LCD as reminders when another switch must be held or the selection is locked out. The innovative servo bias input on the standard 5-pin connector provides a programmable, regulated voltage to accommodate a wide variety of electret microphones. Two bicolor LEDs make adjusting input levels for proper modulation easy and accurate.

The splash-proof housing is machined out of a single block of aluminum, which is then plated with a superhard, non-corrosive coating. The SM Series transmitters are equally at home in theatre, television and film where temperature and environmental extremes require superior performance under the most demanding conditions.

CONSUMER ALERT

Most users do not need a license to operate this wireless microphone

system.  Nevertheless, operating this microphone system without

license is subject to certain restrictions:  the system may not cause

harmful interference; it must operate at a low power level (not in

excess of 50 milliwatts); and it has no protection from interference

from any other device.  Purchasers should also be aware that the FCC

is currently evaluating use of wireless microphone systems and these

rules are subject to change.  For more information, call the FCC at

1-888-CALL-FCC (TTY: 1-888-TEL-FCC) or visit the FCC’s

wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
