About Lectrosonics SMWB

Why choose the Lectrosonics SMWB Single Battery Wideband Beltpack Transmitter This advanced and reliable piece of audio equipment is designed to cater to professionals in the film, television, theater, and live event industries who demand both exceptional operating range and extended battery life. The SMWB series stands out with its selectable output power of 25, 50, and 100 mW, allowing users to optimize the balance between range and battery longevity to suit their specific needs.

Crafted for durability, the transmitter's housing is machined from solid aluminum blocks, ensuring a lightweight yet rugged package that can withstand the rigors of on-location work. Its special non-corrosive finish is built to resist the challenges of saltwater exposure and perspiration, making it suitable for use in even the most extreme environments.

The innovative DSP-based design of the SMWB transmitter ensures compatibility with all Digital Hybrid receivers, as well as backward compatibility with Lectrosonics 200 and 100 Series, IFB receivers, and some analog receivers from other manufacturers. This versatility is further enhanced by the wide frequency tuning range, offering 3072 selectable frequencies in 25 or 100 kHz steps, which is essential for navigating the crowded RF spectrum in today's RF-intense, multichannel venues.

For precise audio control, the transmitter features input gain adjustment in 1 dB increments over a 44 dB range and an adjustable low-frequency audio roll-off with multiple settings to manage subsonic and very low-frequency content. The unique Lectrosonics servo bias input circuitry, along with a standard TA5M type jack, accommodates a variety of input sources, from electret lavaliere mics to dynamic mics or line-level signals.

The high-quality audio limiter, with more than 30 dB of range, employs a dual-release envelope to maintain acoustic transparency and low distortion, safeguarding the audio chain from overload. Hands-free setup and adjustment are made simple with audible tones, and the transmitter can be put into a sleep mode to conserve battery power during setup, then easily awakened for operation.

Ease of use is further emphasized by the water-resistant control panel, which features an LCD, membrane switches, and multi-color LEDs for quick and accurate input gain adjustments, frequency selection, and compatibility mode settings. The battery compartment is designed to accept lithium AA batteries, offering a practical solution for power management.

In addition to its primary function as a transmitter, the SMWB offers an alternate recording function, allowing it to be used as a standalone recorder. The industry-standard .wav (BWF) file format ensures compatibility with virtually any audio or video editing software, adding another layer of versatility to this high-quality device.

With its combination of innovative features, reliable performance, and Lectrosonics' reputation for producing top-tier audio equipment, the SMWB Single Battery Wideband Beltpack Transmitter is a superior choice for professionals seeking to elevate their audio transmission capabilities.
