Nick and Mike of Talamas share how Lectrosonics SMWB and SMDWB transmitters solves the issues of finding a open RF frequency to transmit on and having a portable recorder for your talent to wear?


The DSP-based design works with all Digital Hybrid receivers, and is backward compatible for use with Lectrosonics 200 and 100 Series, IFB receivers and some analog receivers from other manufacturers in addition to its native Digital Hybrid Wireless® operating mode.
The input section features the unique Lectrosonics 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 ahead of the first mic preamp to protect the entire audio chain from overload. The limiter has a range of more than 30 dB for excellent overload protection, and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion of brief transients and longer duration peaks.

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. The battery compartment accepts lithium AA batteries.
The SMWB housing is 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.

Alternate Recording Function
Instead of transmitting, the SMWB may also be used as a recorder. The industry standard .wav (BWF) file format is compatible with essentially any audio or video editing software.
NOTE: The transmitting and recording functions cannot be done simultaneously. Users must choose to transmit or record.

Frequency Tuning Range
RF-intense multichannel and mobile venues must have a broad selection of frequencies available to alleviate interference problems, especially with the emergence of DTV telecasts. 3072 frequencies are selectable in 25 or 100 kHz steps across the broad tuning range of each frequency band.

Features

• Selectable output power to maximize battery life or operating range
• Ultra-lightweight, corrosion resistant housing
• Water resistant seals for use in damp environments
• LCD interface with lockout option
• Programmable compatibility modes for use with a wide variety of different receivers
• Servo Bias input circuitry
• IR (infrared) port for fast setup
• Covers 3 standard frequency blocks
• Update firmware in the field via Micro SD card reader
• Alternate use as recorder on internal microSDHC memory card
