The DBSM single-AA and DBSMD dual-AA digital bodypack transmitters are the latest in the long and hugely successful SM Series of miniature transmitters and are part of the Lectrosonics digital ecosystem. The new models feature a tuning range covering the A1 and B1 bands from 470-608 MHz.
The new transmitters include high-efficiency circuitry for extended run time, and offer RF power selections at 10, 25 and 50 mW. In addition, a new, selectable high-density transmission mode (HDM) allows for much tighter channel spacing (200 kHz between carriers), yielding more than double the operating frequencies per available spectrum. The units can be configured as either transmitters or recorders, with files stored on microSD card memory in the industry standard Broadcast Wave .wav (BWF) format at 24 bits, 48 kHz sample rate.
