Lectrosonics SMWB (single AA battery) and SMDWB (dual AA battery) Digital Hybrid Wireless SM Series transmitters provide several innovative features. They can act as transmitters, body-worn recorders, as well as provide wideband tuning. The units tune across three standard frequency blocks and come in several frequency ranges for North American and export markets, plus selectable RF power. They feature a standard TA5 connector with servo-bias mic input that connects to lavalier microphones. A Micro SD memory card allows recording in Broadcast Wave (.wav) format, plus allows for firmware updates while in the field. SMWB and SMDWB feature highly visible backlit LCDs, IR ports for quick setup with IR equipped receivers and easy integration with a larger wireless system using Lectrosonics Wireless Designer software.
