The Lectrosonics SMV Super Miniature Wireless Microphone Transmitter incorporates Lectrosonics patented Digital Hybrid Wireless technology into a package no bigger than a pager. The SMV transmitter is miniature in size yet rugged enough to withstand rigorous daily use in the field or in studios.
To meet the demand for both extended operating range and extended battery life, this version of the SMV transmitter offers a selectable output power of 50, 100 or 250 mW. The 50mW option is provided for some theatrical applications, where the system design specifies lower transmitter power. Channel spacing is also selectable, with 100 and 25 kHz options available. With the spacing set to 100 kHz, the SMV transmitter offers 256 user-selectable UHF frequencies in this block; if that's not enough, setting the spacing to 25 kHz gives you up to 1000 frequencies to work with.
Lectrosonics patented Digital Hybrid technology revolutionizes wireless microphone transmission. Digital audio signal is converted and encoded for analog transmission, then decoded and converted back to digital audio at the receiver. The result is an exceptionally low noise floor as the compandor circuit is eliminated and clear audio reception is retained at greater distances.
The Switchcraft TA5M audio input has a user-calibrated 44 dB gain range, and accepts electret lavalier mics, dynamic mics, or line-level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB and a dual-release envelope, making the limiter transparent while maintaining low distortion.
The non-corrosive, machined aluminum casing is splash proof and features an LCD display with membrane switch control panel. The transmitter is powered by one AA lithium, NiMH, or alkaline battery for up to 7.25 hours (lithium). The SMV transmitter is completely compatible with all Lectrosonics Digital Hybrid wireless receivers as well as older Lectrosonics analog receivers.
