Lectrosonics SMWB-A1 Miniature Wideband Transmitter (A1: 470 to 537 MHz)

Advanced Functionality in a Compact Design
The Lectrosonics SMWB-A1 Miniature Wideband Transmitter epitomizes cutting-edge wireless audio technology in a remarkably compact frame, making it a versatile tool for professionals engaged in ENG (Electronic News Gathering), EFP (Electronic Field Productions), and broadcast interviews. Its dual-function capability allows it not only to transmit audio but also to record directly onto microSDHC cards, providing flexibility in various field situations.

Optimized Power for Extended Performance
Offering selectable output power levels of 25, 40, and 100mW, the SMWB-A1 is designed to balance between extended battery life and increased operating range. This feature allows users to adapt the transmitter's performance to the specific requirements of their recording environment, ensuring optimal functionality whether in quiet, controlled settings or in more demanding, expansive locations.

High-Quality Audio Transmission
Lectrosonics' Digital Hybrid Wireless® technology combines 24-bit digital audio processing with an analog FM link, delivering the best of both worlds. This innovative approach minimizes dropouts and audio artifacts while maintaining a robust signal strength over a wide operational range, ensuring clear, reliable audio capture in even the most challenging conditions.

Sophisticated Input and Filtering Options
The SMWB-A1 is equipped with a TA5M 5-pin input, accommodating a wide variety of audio sources from dynamic microphones and electret lavalier mics to line-level devices. Input gain is adjustable in precise 1 dB increments across a 44 dB range, complemented by selectable low-pass filters to manage low-end disturbances effectively. Additionally, the unit features Lectrosonics' proprietary servo-bias input circuitry and a DSP-controlled analog limiter, which ensures the integrity of the audio signal even under stressful conditions.

Durable and Weather-Resistant Construction
Built to endure the rigors of field use, the SMWB-A1 sports a lightweight, corrosion-resistant aluminum housing with water-resistant seals, making it ideal for use in damp environments. Its practical design includes a flexible steel-cable antenna and an LCD interface with a lockout feature, ensuring easy handling and configuration under diverse operating conditions.

Versatile Recording Capability
Beyond its transmission capabilities, the SMWB-A1 offers an internal recording function, capturing high-quality 24-bit/44.1 kHz WAV files directly to a microSDHC card when conditions preclude live transmission. This feature is particularly useful in RF-restricted environments or when backup recordings are required, adding an extra layer of reliability to its already robust feature set.
