Overview

The DSSM is the enhanced, fully digital successor to the SSM, while being IP57 rated for watertightness and offering dock charging capability.

The IP57 rating indicates that the unit is protected against dust ingress while also withstanding water immersion up to 1 meter for 30+ minutes – perfect for the most demanding work environments. All while allowing for quick battery swap-outs.

The DSSM is ideal for theater, TV, film and broadcast environments where concealment and water-resistance is required. The DSSM offers an extensive feature set and performance packed into an exceptionally compact housing, compatible with all current Lectrosonics digital receivers, including the DSQD, DCR822, DSR, DSR4, M2Ra, and DCHR.

The DSSM includes specially developed, high efficiency circuitry for extended operating time on the rechargeable LB-50 battery. RF power selections are offered at 10 and 35 mW (D2 compat mode) and a special high density (HDM) mode at 2 mW.
