The Lectrosonics LM transmitter is a wireless digital hybrid belt-pack microphone transmitter for lavalier or headset type microphones. The LM transmitter features Digital Wireless Hybrid technology which combines a 24-bit digital audio chain with an FM radio link. The transmitter's digital signal path eliminates the need for an analog compander, resulting in pristine, noise free audio fidelity throughout.
Internal DSP provides compander emulation so that the unit can be switched for use with 100, 200 and 400 series Lectrosonic receivers. The input section features a tap suitable for any microphone or line level audio source. 0 / -20dB LED's are provided for accurate level settings, and an "Audio Level" dial is located on the top face of the unit. Two rotary frequency adjuster dials are located on the side panel. The 1.6MHz is a coarse adjustment and the 100kHz is the fine. The unit is powered with a 9 volt battery, and is enclosed in a rugged metal enclosure made to withstand the rigors of road use.
