Lectrosonics SMDWB

Description

Lectrosonics SMDWB E01 Wideband Beltpack Transmitter

To meet the demand for both extended operating range and extended battery life, the “WB” series SM transmitters offer selectable output power of 25, 50 and 100 mW. With higher power output, the operating range is improved at the expense of battery life. When range is not an issue, a lower power level can be used to extend the battery life.

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

The transmitters offer hands free setup and adjustment using audible tones. They can be put to sleep to conserve battery power during setup while buried inside costuming, then awakened for normal operation when the production begins. Other features include input gain adjustment in 1 dB increments over a 44 dB range and adjustable low frequency audio roll-off for 3 dB down points at 35, 50, 70, 100, 120 or 150 Hz to control subsonic and very low frequency audio conten

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.
