USA - High-end wireless technology manufacturer Lectrosonics is introducing what it claims to be the world's smallest professional audio wireless transmitter.

Scheduled to be unveiled at NAB 2005 in Las Vegas, SM (Super Mini), this transmitter is said to delivering 107dB signal-to-noise ratio and flat frequency response to 20kHz. Lectrosonics' Digital Hybrid Wireless technology uses both 24-bit digital audio and analogue FM signal transmission methods to encode a digital signal into a robust analogue format for transmission over a UHF FM carrier.

The SM's receiver captures the signal and DSP circuitry recreates the original digital audio. Says Lectrosonics, "This unique system represents the best of both wireless worlds: exceptional digital audio qualitycombined with the spectrum efficiency and long range of highly-optimised FM wireless systems."

Larry Fisher, Lectrosonics' president, comments, "Engineering a transmitter that is smaller, while outperforming industry standards, has been a labour of love for Lectrosonics." The SM is offered in the nine standard Lectrosonics frequency groups with 256 frequencies each.
