The Lectrosonics DSSM digital wireless mini transmitter has an analog input limiter with 30dB range to prevents digital clipping 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 more than 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. Lectrosonics DSSM features: Extremely compact - ideal for theater and sports broadcasting IP57 rated for moisture resistance High density mode for maximum channel counts in limited spectrum Selectable power; 10 or 35 mW (D2 mode) Offers over 6000 frequencies across a wide UHF range Two-way IR port for easy set-up Firmware updates via USB/Wireless Designer Wide range input gain control in 1 dB steps Dock chargable with optional CHSDSSM unit Lectrosonics DSSM specifications: Operating Frequencies: DDSSM - A1B1 470.100 - 607.950DSSM/E01-A1B1: 470.100 - 614.375DSSM-B1C1 (US) 537.600 - 607.950614.400 - 615.950653.050 - 662.950DSSM/E01-B1C1: 537.600 - 691.175DSSM/E07-941: 941.525 - 951.575953.025 - 956.225956.475 - 959.825 Frequency Selection Steps: 25kHz RF Power output: Selectable; 10, 35 mW or 2mW (HD mode) Compatibility Modes: HDM or D2 (all models) Frequency Stability: ± 0.002% Spurious radiation: Compliant with ETSI EN 300 422-1 Equivalent input noise: –120 dBV (A-weighted) Input level: Nominal 2 mV to 300 mV, before limiting.
