High-end wireless technology manufacturer Lectrosonics is introducing the SM (for “Super Mini”), the “world’s smallest professional audio wireless transmitter” at NAB 2005 (Booth #N3611) in Las Vegas.
When used in its native Digital Hybrid mode, the SM performs without an analog compandor or the headroom-limiting pre- and de-emphasis found in most analog systems. 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 analog format for transmission over a UHF FM carrier. The SM’s receiver captures the signal, and DSP circuitry recreates the original digital audio.
Operating on a single AA battery, the Lectrosonics SM features 100mW of transmitting power, compatibility emulation modes, and an LCD for easy frequency and audio level adjustment. 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 lavalier 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 emulation modes give engineers increased operational flexibility and permits use with a variety of pre-existing analog receivers.
The SM’s body is machined from a solid aluminum block for featherweight rigidity and is finished with a special non-corrosive material. Likewise used on NASA interstellar vehicles, the finish resists the destructive effects of salt water and perspiration. The single AA battery provides over four hours of operation with lithium or NiMH sources.
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.
