About Lectrosonics SMQV

From the innovative minds at Lectrosonics, the SMQV Variable Power Miniature Transmitter emerges as a pinnacle of portable, high-tech audio transmission. This back-lit, double battery version offers unparalleled versatility with selectable RF power outputs of 50, 100, and 250mW, catering to a wide range of professional audio applications. Whether for live theater productions requiring discreet, low-power operation or for robust, high-demand environments, this transmitter adapts seamlessly to your needs.

Crafted with durability in mind, the SMQV's housing is precision-machined from solid aluminum blocks, ensuring a lightweight yet rugged design that stands up to the rigors of on-location work. Its special non-corrosive finish is engineered to withstand exposure to saltwater and perspiration, making it an ideal choice for use in extreme conditions.

The high-tech servo bias input circuitry is a standout feature, offering a standard TA5M jack compatible with a variety of microphones, from electret lavaliere to dynamic models, or even line-level signals. This advanced input system is designed to be more resistant to overload, eliminating the need for pads on certain microphones and ensuring a cleaner, more reliable signal.

Incorporating a DSP-controlled analog audio limiter, the SMQV ensures exceptional overload protection with a dynamic range exceeding 30 dB. Its dual-release envelope maintains acoustic transparency and low distortion, even with rapid transient recovery and sustained high levels, preserving the integrity of your audio.

The water-resistant control panel boasts an intuitive LCD, membrane switches, and multi-color LEDs for swift and precise adjustments to input gain, frequency, and compatibility mode selection. The battery compartment is compatible with both lithium and rechargeable AA batteries, offering extended field use.

Leveraging Lectrosonics' proprietary Digital Hybrid Wireless Technology, the SMQV overcomes channel noise with a novel approach. By digitally encoding the audio in the transmitter and decoding it in the receiver, while still utilizing an analog FM link, this system delivers the full benefits of FM transmission without the artifacts of analog compandors.

This powerful and portable transmitter operates across a broad frequency range, including 470.1-495.6 MHz, 486.4-511.9 MHz, 512-537.5 MHz, 537.6-563.1 MHz, 563.2-588.7 MHz, 588.8-607.9 MHz, 614.1-614.3 MHz, 614.4-639.9 MHz, 640-665.5 MHz, and 665.6-691.1 MHz. It is backward compatible with Lectrosonics 200 and 100 Series, IFB receivers, and some other brands of analog wireless receivers, ensuring a broad scope of use with existing equipment.

The Lectrosonics SMQV Variable Power Miniature Transmitter with Pouch is a testament to the brand's commitment to quality and innovation, offering audio professionals a powerful, versatile, and reliable solution for their wireless transmission needs.
