SM
Thank you for selecting the Lectrosonics SM ultra
miniature transmitter. The unique design provides
several distinct features for professional applications:
Outstanding RF operating range
Superb audio quality
Ultra-lightweight, corrosion resistant housing
Water resistant seals for use in damp environments
Programmable compatibility modes for maximum
versatility
The Digital Hybrid Wireless
Pending) combines 24-bit digital audio with analog FM
resulting in a system that has the same operating range
as analog systems (plus the graceful failure at the limits
of that range), the same spectral efficiency as analog
systems, the same long battery life as analog systems,
but with the excellent audio found in digital systems.
The SM uses a standard Lectrosonics 5-pin type input
jack for use with electret lavaliere mic, dynamic mic, or
line level signals. A water resistant control panel with
LCD, membrane switches and multi-color LEDs make
input gain adjustments and frequency and compatibility
mode selection quick and accurate, without having to
view the receiver. The battery compartment accepts an
AA lithium battery. Plus, the SM is machined from a
solid aluminum block to provide an extremely light
weight and rugged package. A special non-corrosive
finish (the same one used by NASA) resists salt water
exposure and perspiration in extreme environments.
The DSP-based design works with all Digital Hybrid
recievers, and is backward compatible with
Lectrosonics 200 and 100 Series and IFB receivers and
some other brands of analog wireless receivers. Only
the SM transmitter is covered in this manual. Compan
ion receivers are covered in separate manuals.
