Lectrosonics DSSM/E01 Digital Wireless Water-Resistant Micro Transmitter
The DSSM is the smallest transmitter with an IP57 rating and a removable battery, and represents the state of the art in miniature, water resistant transmitter design. It has a host of unique and powerful features applicable to a wide variety of applications and use cases.
Features:
- IP57 rating: the DSSM will resist water ingress for 30 minutes or more when submerged under 1 metre of water
- Removable battery: The DSSM uses the LB-50 rechargeable LiOn battery (PN#40106-1) from the IFBR1B and SSM products. This means that existing charging bays like the CHS12LB50, CHS12LB50a, and 40117 dual USB charger can be used with this new transmitter.
- Easy-to-use onboard buttons and rich display, with the same menu structure as the DBSM family transmitters
- USB jack located inside the battery compartment for firmware updates in the field, using Wireless Designer software
- Drop-in charging with the optional CHSDSSM charging bay. This bay charges 4 units or batteries and can be connected to additional units so that up to 16 batteries or units in any combination can be charged from a single DCR5/9AU power supply (just like for the similar CHSIFBR1B).
- All-metal construction
- Removable antenna with SMA mount
- Standard miniature 3-pin connector
- RF Power settings at 50, 25, and 10 mW in D2 mode and 4 mW for HDM mode
- AES 256-bit CTR encryption with four key policies including Universal, Shared, Standard, and Volatile. This covers a wide variety of use cases including government, corporate, & sports coverage
- Compatible with DSQD, DCHR, M2Ra, DSR, DSR4, and DCR822 receivers
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 metre for 30+ minutes – perfect for the most demanding work environments. All while allowing for quick battery swap-outs.
The DSSM is ideal for theatre, 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 settings at 50, 25, and 10 mW in D2 mode and 4 mW for HDM mode
