Lectrosonics smdb/E01 Block 21

Frequency: 537.6 - 563.1 MHz.
Price for one transmitter
The SMDb transmitter provides several distinct features for professional applications:

superb, compandor-free 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 transmitter is remote control compatible for hands free setup and adjustment using audible tones delivered into the microphone. The transmitter can be put to sleep to conserve battery power during setup while the transmitter is buried deep inside costuming, then awakened for normal operation when the production begins. Other features include frequency and audio level adjustment and control lockout.

A water resistant control panel with LCD, membrane switches and multi-color LEDs make input gain adjustments, frequency and compatibility mode selection quick and accurate, without having to view the receiver. The battery compartment accepts 2 AA batteries. The housings are machined from solid aluminum blocks to provide an extremely lightweight and rugged package. A special non-corrosive finish resists salt water exposure and perspiration in extreme environments.

The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

"Digital Hybrid Wireless" combines 24-bit digital audio with an analog FM radio link to provide outstanding audio quality and the extended operating range of the best analog wireless systems. The design overcomes channel noise in a dramatically new way, digitally encoding the audio bitstream in the transmitter and decoding it in the receiver, yet sending the encoded information via an analog FM wireless link. This proprietary DSP algorithm eliminates a compandor circuit and its artifacts and preserves the RF spectral footprint of analog FM designs to simplify multi-channel coordination with exisiting analog wireless systems.
