Table Of Contents - Lectrosonics SMa Instruction Manual

Thank you for selecting a Lectrosonics SM Series
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 use with a
wide variety of different receivers
The Digital Hybrid Wireless
7,225,135) combines 24-bit digital audio with analog
FM resulting in a system that has the same operating
range as analog systems, the same spectral efficiency
as analog systems, the same long battery life as analog
systems, plus the excellent audio fidelity typical of pure
digital systems.
The SM Series transmitters use a standard Lectroson-
ics 5-pin type input jack for use with electret lavaliere
mics, dynamic mics, 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 bat-
tery compartment accepts AA lithium or rechargeable
batteries. The SM is machined from a solid aluminum
block to provide an extremely lightweight and rugged
package. A special non-corrosive finish resists salt wa-
ter exposure and perspiration in extreme environments.
The DSP-based design works with all Digital Hybrid
recievers, and is backward compatible for use with
Lectrosonics 200 and 100 Series and IFB receivers and
some other brands of analog wireless receivers. Com-
panion receivers are covered in separate manuals.
