The Lectrosonics dual battery SMD model doubles the battery life of the SM with the same feature set. It still sets a new standard for size, power, reliability and functionality as the ultra miniature SM transmitter.

The SM Series family brings Digital Hybrid Wireless™ technology to miniature transmitters in several different configurations for essentially any wireless microphone application with a lavalier microphone. The tiny size of the single battery SM model makes concealment easy, yet with a full 100 mW output, it does not sacrifice performance.

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