Lectronics Intros Mini Audio Transmitter
April 12, 2005
Rio Rancho, NM - Lectrosonics is introducing what it calls the world's smallest professional audio wireless transmitter at NAB.
Called SM (for "Super Mini"), the 100 mW SM packs all user controls onto an easy to operate control panel that includes an LCD, four membrane switches for adjusting operating frequency and modulation level, plus both modulation and power indicators into a package not much bigger than two AA batteries, the manufacturer describes.
The switches can also be used to set compatibility modes, allowing the SM to work with all of Lectrosonics Digital Hybrid Wireless receivers, plus Lectrosonics 200 Series and 100 Series analog products (and even analog receivers from some other manufacturers), and Lectrosonics IFB systems.
When used in its native Digital Hybrid mode, the SM performs without the hindrance of an analog compandor or the headroom-limiting pre- and de-emphasis found in most analog systems. Delivering 107 dB signal-to-noise ratio and flat frequency response to 20 kHz, Lectrosonics' patent-pending Digital Hybrid Wireless™ technology uses both 24-bit digital audio and analog FM signal transmission methods to encode a digital signal into a robust analog format for transmission over a UHF FM carrier. The SM's receiver captures the signal and DSP circuitry recreates the original digital audio. This unique system represents the best of both wireless worlds: exceptional digital audio quality combined with the spectrum efficiency and long range of highly-optimized FM wireless systems.
The standard Lectrosonics TA5M five-pin input jack is wired to a newly developed audio input circuit allowing for an extremely wide dynamic range and is compatible with electret lavaliere mics, dynamic mics, and line level signals. While the SM's added RF power allows for extended range and greater resistance to interference, its frequency agility (256 channels) and compatibility modes provides increased operational flexibility and permits use with a variety of pre-existing analog receivers.
The small, yet strong and splash-proof body of the SM - machined from a solid aluminum block for featherweight rigidity - is finished with the same non-corrosive material used on NASA interstellar vehicles. The finish resists the destructive effects of both salt water and perspiration. The single AA lithium battery provides over six hours of operation.
The Lectrosonics SM is offered in the nine standard Lectrosonics frequency groups with 256 frequencies each. MSRP is $1,650 and is scheduled to be available in May 2005.
