Lectrosonics SM User Manual

Page 2

Thank you for selecting the Lectrosonics SM ultra-min

iature 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

design (US Patent Pend

ing) 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 re

cievers, and is backward compatible with Lectrosonics

200 and 100 Series and IFB receivers and some other

brands of analog wireless receivers. Only the SM trans

mitter is covered in this manual. Companion receivers

are covered in separate manuals.
