About Lectrosonics Transmitter

Under the umbrella of advanced audio technology, the SMV-22 Miniature Wireless Microphone Transmitter, Block 22: 537.600-563.100, stands out as a high-quality, durable, and compact device. This innovative product is engineered by Lectrosonics, a reputable brand known for its superior audio equipment.

The SMV-22 is designed to transmit audio signals wirelessly to a receiver, making it an ideal choice for live performances, events, and professional recording in the film, television, and music industries. Its wide frequency range of 537.6-563.1 MHz sets it apart from its competitors, offering a broader operating range.

This advanced wireless microphone transmitter offers selectable output power ranging from 50, 100, and 250 mW, allowing users to optimize both operating range and battery life. When the range is not a concern, power can be reduced to extend battery life, making it a versatile choice for different recording environments.

The SMV-22 is compatible with RM and RM2 remote control units, enabling hands-free setup and adjustments. Its sleep mode feature conserves battery power during setup, especially when the transmitter is concealed within costumes, and can be easily awakened when the production begins.

The transmitter boasts a DSP-based design that works with all Digital Hybrid receivers and is backward compatible with Lectrosonics 200 and 100 Series and IFB receivers, as well as some other brands of analog wireless receivers. Its input section features unique servo bias input circuitry with a standard TA5M type jack, suitable for use with electret lavaliere mics, dynamic mics, or line-level signals.

The SMV-22 also features a DSP-controlled analog audio limiter, providing more than 30 dB range for excellent overload protection. This ensures the audio chain is protected from overload, maintaining low distortion and preserving short-term dynamic changes.

Designed with a water-resistant control panel, LCD interface, and multi-color LEDs, the SMV-22 ensures quick and accurate adjustments for input gain, frequency, and compatibility mode selection. The battery compartment is compatible with lithium or rechargeable AA batteries, and the housing is machined from solid aluminum blocks for lightweight and rugged durability.

The SMV-22 Miniature Wireless Microphone Transmitter is not just a device; it's a testament to Lectrosonics' commitment to providing innovative, high-quality audio solutions. With its wide frequency range, high power output, and long battery life, it's the perfect tool for professionals in the entertainment industry.
