Lectrosonics Debuts Their Smallest Wireless Transmitter
 April 1, 2005
Wireless technology manufacturer
Lectrosonics is introducing what's being billed as the world's smallest professional audio wireless
transmitter at NAB 2005 in Las Vegas, Nevada. Simply called the SM (for
"Super Mini"), this compandor-free wireless transmitter
is housed in a tiny and splash-proof package.
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 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. 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:
digital audio quality combined with the spectrum efficiency and long range
of FM wireless systems.
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 a 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 small and splash-proof body of the SM - machined from a solid
aluminum block for featherweight rigidity - 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.
