Description

Overview

The DSSM is an enhanced, fully digital successor to the SSM with an IP57 rating for watertightness and dock charging capability. Dual-battery USB charger included; dock charger sold separately.

It's 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 IP57 rating indicates that the unit is protected against dust ingress while also withstanding water immersion up to 1 meter for 30+ minutes, as well as sweat, rain, and other moisture sources. It's engineered to still allow for quick battery swap-outs.

The DSSM includes specially developed, high efficiency circuitry for extended operating time on the rechargeable LB-50 battery. RF power selections are offered at 50, 25, and 10 mW (D2 compat mode) and a special high density (HDM) mode at 4 mW.

The servo bias input 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. The limiter in the preamp can cleanly handle signal peaks over 30 dB above full modulation, allowing the input gain to be set high enough to achieve the maximum signal to noise ratio, yet provide protection against input overload.

The audio input jack is a common subminiature 3-pin connector with a threaded collar adding additional ruggedness. An IR (infrared) port next to the antenna allows transfer of frequency and compatibility mode settings, and encryption keys.

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 defeatable 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 housing is constructed of machined aluminum alloy treated in the conductive, super hard electroless nickel ebENi finish.

A flexible, repositionable wire belt clip (to orient the antenna facing up or down) is included.

The DSSM battery charging station (sold separately) provides a convenient and organized means of recharging up to 4 LB-50 batteries or DSSM transmitters in larger systems with numerous batteries in regular use. Each charging module may be daisy-chained to 3 additional modules using a single AC-DC power supply (DCR5/9AU, sold separately) for a total of 16 units charging at once (LB50’s and/or DSSMs).

Consumer Alert

Starting in 2017, the 617-652 MHz and 663-698 MHz frequencies are being transitioned by the Federal Communications Commission (FCC). Users of wireless microphone devices that operate in any portion of those frequencies must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
