Lectrosonics is unveiling three new additions to the SM Super Mini
transmitter line at NAB 2006. Introduced at NAB 2005, the SM transmitter
reigns as one of world's smallest professional audio wireless transmitters.
Right from the starting gate, the SM transmitter filled a niche for users
who wanted an incredibly high-powered, cost-effective, advanced wireless
transmitter in a remarkably tiny and splash-proof package.
The first of the three new additions to the SM family is the SMD (SM-Dual)
transmitter using two AA batteries and therefore doubling the battery life
of the original unit. Next is the SMQ (SM "Quarter Watt") transmitter which
has been designed to deliver 250mW power for longer range and greater
resistance to interference than the standard SM (100mW transmitter) - also
using two AA batteries. And finally the RM (Remote unit) was created for
programming and operation of the SM transmitter family, including the new
SMD and SMQ units. The RM communicates with the transmitter via a
proprietary audio signal through the transmitter's microphone so it does not
rely on line of sight, as do infrared systems. This allows the transmitter
to be buried in a costume and still respond to commands updating operating
frequency, audio level, sleep, control surface lockout, etc. The RM is
supplied with a lanyard and quick-release mechanism for ease of deployment
in the field.
The key features of the SM transmitters include their ability to function in
the Digital Hybrid™ mode, without the hindrance of an analog compandor in
the signal chain or the headroom limiting pre- and de-emphasis found in many
other 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: exceptional digital audio
quality, combined with the spectrum efficiency and long range of highly
optimized FM wireless systems.
