To meet the demands for a variety of RF environments and applications, the “WB” series SM transmitters offer selectable output power of 25, 50 and 100 mW (25 and 50 mW for export versions). With higher power output, the operating range is improved, or, a more secure link can be relied upon for high RF noise environments. Battery life is unchanged with the different RF power selections.

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 content.

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 content. The transmitters also offer selectable output power of 25, 50 and 100 mW (10, 25 or 50 mW for E01). 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 AA batteries (lithium recommended). The 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.

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. Frequencies are selectable in 25 or 100 kHz steps across the broad tuning range of each frequency band.

Recording Function

The record and transmit function can be used simultaneously (only in regions outside the United States). For US models, when the unit is transmitting and recording is turned on, the audio in the RF transmission will stop, but the battery status will still be sent to the receiver.
