Discover the pinnacle of wireless audio transmission with the Lectrosonics SMV Super Miniature Variable Power Transmitter. This single-battery, frequency block 470 model (470.100-495.600MHz) is engineered for professionals who demand both extended operating range and battery life without compromise. With selectable output power of 50, 100, and 250 mW, users can tailor the transmitter's performance to the specific needs of their application - choosing higher power for improved operating range or lower power to prolong battery life.
Crafted with an ultra-lightweight, corrosion-resistant aluminum housing, the SMV transmitter is both durable and compact, making it an ideal choice for field use. Its water-resistant seals ensure reliable performance in damp environments, while the intuitive LCD interface with lockout option provides effortless navigation and security against accidental setting changes.
The SMV transmitter is a testament to versatility, offering programmable compatibility modes for seamless integration with a wide array of receivers. Its advanced servo bias input circuitry is designed to accommodate electret lavaliere mics, dynamic mics, or line-level signals through a standard TA5M type jack.
Equipped with a DSP-based design, this transmitter is compatible with all Digital Hybrid receivers, as well as backward compatible with Lectrosonics 200 and 100 Series and IFB receivers, along with certain other brands of analog wireless receivers. The innovative Digital Hybrid Wireless technology merges digital audio with an analog FM radio link, delivering exceptional audio quality and robust RF performance.
The transmitter's input limiter, with more than 30 dB of dynamic range, ensures protection against overload while maintaining transparency and low distortion. The bicolor LEDs provide clear visual feedback for input gain adjustments, ensuring optimal signal-to-noise ratio and dynamic range.
For challenging RF environments, the transmitter includes a circulator/isolator to minimize intermodulation distortion and protect the output stage. Additionally, a GORE-TEX vent in the battery door prevents moisture ingress, safeguarding the unit against environmental changes.
Remote control capabilities are enhanced with the RM and RM2 units, allowing hands-free setup and adjustments via audible tones. This feature is invaluable when the transmitter is concealed within costuming, enabling quick activation without disturbing the talent or wardrobe.
The SMV transmitter's frequency tuning range is expansive, offering 256 selectable frequencies across a 25.6MHz tuning range to navigate crowded RF landscapes. The battery compartment is designed to accommodate the latest AA battery technology, ensuring extended operating times even at high RF power settings.
In summary, the Lectrosonics SMV Super Miniature Variable Power Transmitter is the epitome of high-tech, portable, and versatile audio transmission, making it the professional's choice for reliable, high-quality wireless communication.
