Lectrosonics is introducing the smallest professional audio wireless transmitter at NAB 2005 in Las Vegas, Nevada (April 16-21). The SM ("Super Mini") is a high-powered, cost-effective, compandor-free wireless transmitter in a tiny and splash-proof package.

Delivering 107dB signal-to-noise ratio and flat frequency response to 20kHz, 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. SM's receiver captures the signal and DSP circuitry recreates the original digital audio. This unique system delivers digital audio quality combined with the spectrum efficiency and the long range of highly optimized FM wireless systems.

Operating on a single AA battery, which provides over four hours of operation with lithium or NiMH sources, the SM features 100mW of transmitting power, compatibility emulation modes, and an LCD for easy frequency and audio level adjustment. The standard Lectrosonics TA5M 5-pin input jack is wired to a newly developed audio input circuit and is compatible with electret lavalier mikes, dynamic mikes, and line level signals. SM has added RF power for greater resistance interference. Its frequency agility (256 channels) and emulation modes provide operational flexibility and permits use with a variety of pre-existing analog receivers.

The small transmitter has a height of 2.25" (not including antenna), width of 1 7/8", depth of 5/8", and weighs 2.8 oz. with battery.

The SM is offered in the nine standard Lectrosonics frequency groups with 256 frequencies each and is scheduled to be available in May 2005.
