Lectrosonics Introduces New Transmitters at NAB 2007

Lectrosonics is introducing a new transmitter as well as new versions of its most popular transmitters at NAB 2007 (booth # N8116) in Las Vegas, Nev. The UM450 (pictured; $1,835) is a new Digital Hybrid Wireless belt-pack transmitter with a current-servo input and 250mW RF output for exceptional range and resistance to interference. The UM400a ($1,360), a new version of Lectrosonics’ most popular transmitter, is also gaining the current-servo input circuit originally developed for the SM Series. The new input enables a wider range of microphone sensitivities and provides a straightforward microphone wiring method.

In the revised SM Series, including the SMa ($1,795) 100mW transmitter, SMDa ($1,875) dual-battery unit, and SMQa ($2,045) 250mW transmitter, a variable highpass filter has been added with control via the front panel menus. A 3dB down point is selectable between 35 and 150 Hz, allowing the transmitters to be optimized for full-range audio or voice transmission, depending on the intended application. In addition, all SM Series transmitters now include a Gore-Tex pressure-equalizing membrane for preventing moisture from entering the housing resulting from expansion and contraction of the air inside the unit due to rapid temperature changes.

On the MM400c, the formerly removable antenna connector (SMA) has been replaced by a newly developed, fixed antenna to increase the water resistance for the most severe weather and environmental conditions.

All current Lectrosonics 400 Series transmitters feature Digital Hybrid Wireless technology for avoiding distortion due to compandor artifacts when used with compatible receivers in 400 Mode. In addition, these transmitters offer compatibility with analog receivers from Lectrosonics and two other manufacturers.

Lectrosonics expects to ship these products in the third quarter of 2007.
