Ideal for theater, TV, film, sports, and broadcast applications where concealment is desired and water-resistance is required, the 941 to 959 MHz Lectrosonics DSSM Micro Digital Wireless Transmitter is the company's smallest transmitter with an IP57 rating and dock-charging capability. The DSSM offers an extensive feature set packed into an exceptionally rugged and lightweight, solid-aluminum housing, and is compatible with all Lectrosonics digital receivers, including the DSR, DSR4, DSQD, DCR822, M2Ra, and DCHR. The servo bias input circuitry can accommodate an electret lavalier mic, a dynamic mic, or a line-level input via the locking, 3-pin LEMO connector.

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 35mW (D2 mode) and at 2mW (Special High Density/HDM mode). The membrane switch panel and OLED display enable quick access to all adjustments and settings.

• The IP57 rating indicates that the unit is protected against dust ingress while also withstanding water immersion up to 3.2' for 30+ minutes—all while allowing for quick battery swap-outs 
• The housing is constructed of machined aluminum alloy treated in the conductive, super hard electroless nickel ebENi finish 
• The audio-input jack is a 3-pin LEMO connector with a threaded collar adding additional ruggedness 

• The optional CHSDSSM battery charging station provides a convenient and organized way of recharging any mix of four DSSM transmitters and/or four LB-50 lithium-ion batteries 
• Full charging of battery takes 3 hours 
• The DSSM transmitter can operate up to 6 hours on a full charge 
• For larger systems with numerous batteries in regular use, the CHSDSSM charger may be daisy-chained to 3 additional CHSDSSM chargers using a single DCR5/9AU AC/DC power supply (available separately) for a total of 16 LB50s and/or DSSMs charging at once 

• The input section features the unique Lectrosonics servo bias input circuitry accepts mic- or line-level signals with a wide range of gain adjustment in 1 dB steps 
• Accurate indications on the display allow precise gain adjustments to be made for the maximum signal to noise ratio and minimum distortion
• A DSP-controlled analog audio limiter is employed ahead of the first mic preamp to protect the entire audio chain from overload. The limiter has a range of more than 30 dB for excellent overload protection, and a dual-release envelope that makes the limiter acoustically transparent while maintaining low distortion of brief transients and longer duration peaks 
• Selectable, low-frequency roll-off at 35, 50, 70, 100, 120, and 150 Hz

• The membrane switch panel and OLED display enable access to all adjustments and settings. The menu structure is easy to navigate 
• Battery status is indicated by a bi-color LED that is green with a fresh battery, then turns to red as the battery runs down, and finally starts blinking red when there are only a few minutes of runtime remaining 

• The DSSM offers 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, and sports coverage 

• LectroRM (available separately) is a third-party mobile application for iOS and Android smartphone operating systems. Its purpose is to make changes to the settings on the DSSM transmitter by delivering encoded audio tones to the microphone attached to the transmitter 
• When the tone enters the transmitter, it is decoded to make a change toa variety of different settings such as input gain, frequency, and more 

• Compatible with DSQD, DCHR, M2Ra, DSR, DSR4, and DCR822 receivers
• Audio-input connector: LEMO 3-pin
• IP57 rating: avoids water ingress for 30 minutes or more when submerged under 3.3' of water
• Removable battery: the DSSM uses an LB-50 rechargeable lithium-ion battery
• Easy-to-use onboard buttons and rich display, with the same menu structure as the company's DBSM family of transmitters
• USB jack located inside the battery compartment for firmware updates in the field, using Wireless Designer software
• All-metal construction
• Removable antenna with SMA mount
• RF Power settings at 10 and 35mW in D2 mode and 2mW 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, and sports coverage)
• Includes flexible, repositionable wire belt clip
