About Lectrosonics SMQV

It is essential for professionals in the audio industry to have reliable and versatile equipment, and the Lectrosonics SMQV Super Miniature Variable Power Transmitter stands out as a top-tier choice. This compact and portable transmitter is engineered to deliver exceptional audio quality with a broad frequency tuning range of 470.100-495.600MHz, making it ideal for a wide array of applications, from film and television production to live events.

Crafted with durability in mind, the SMQV features a corrosion-resistant, ultra-lightweight aluminum housing, ensuring it can withstand the rigors of on-location work. The housing is finished with a special coating that resists salt water and perspiration, making it suitable for use in extreme environments. Additionally, water-resistant seals provide further protection, allowing the transmitter to perform reliably in damp conditions.

The selectable output power of 100 or 250 mW, with a 50 mW option for specific theatrical applications, allows users to optimize for either extended operating range or battery life. This flexibility is a significant advantage over alternative transmitters with more limited power options. The input section boasts Lectrosonics' unique servo bias input circuitry, accommodating a variety of sources through a standard TA5M type jack, including electret lavaliere mics, dynamic mics, or line-level signals.

A DSP-controlled analog audio limiter precedes the A-D converter, offering more than 30 dB of range for superior overload protection. Its dual release envelope ensures the limiter is acoustically transparent, maintaining low distortion and quick recovery from transients without audible side effects. The slow recovery from sustained high levels preserves short-term dynamics while keeping audio distortion minimal.

The transmitter's control panel is designed for efficiency, featuring an LCD, membrane switches, and multi-color LEDs for straightforward input gain adjustments, frequency selection, and compatibility mode settings. The battery compartment is compatible with both lithium and rechargeable AA batteries, providing users with power options to suit their needs.

Lectrosonics' Digital Hybrid Wireless technology is at the heart of the SMQV, combining digital audio with an analog FM radio link. This innovative design eliminates the artifacts associated with traditional analog compandors, offering pristine audio quality and the robust RF performance of the best analog systems. The system is backward compatible with Lectrosonics 200 and 100 Series and IFB receivers, as well as some other brands of analog wireless receivers.

For remote control, the SMQV can be paired with the Lectrosonics RM remote, which uses an audible tone to adjust transmitter settings without disturbing talent or wardrobe. This feature is particularly useful in situations where discretion and speed are paramount.

In summary, the Lectrosonics SMQV Super Miniature Variable Power Transmitter is an advanced, high-tech solution for professionals seeking a durable, compact, and high-performance audio transmission device. Its extensive frequency range, superior audio limiter, and compatibility with various receivers make it a versatile tool for any audio professional's toolkit.
