Super-Minature Belt Pack Transmitters

Thank you for selecting a Lectrosonics SM Series

ultra-miniature transmitter. The unique design provides

specialized 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® design (US Patent

7,225,135) combines 24-bit digital audio with analog

FM resulting in a system that has the same excellent

operating range, spectral efﬁciency and long battery life

as analog systems, plus the excellent audio ﬁdelity typi-

cal of pure digital systems.

The SMDa Series transmitters use a standard Lec-

trosonics 5-pin type input jack for use with electret lava-

liere 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

battery compartment accepts AA lithium or recharge-

able batteries. The housing is machined from a solid

aluminum block to provide an extremely lightweight and

rugged package. A special non-corrosive ﬁnish resists

salt water exposure and perspiration in extreme envi-

ronments.
