The Lectrosonics LMb is a Digital Hybrid Wireless® UHF transmitter that can be configured to operate as a “one touch” device with a single power on/off switch on the top panel, or with full access to all operational parameters using the side panel membrane switches and LCD interface. The top panel switch can also be configured to provide a mute or talkback function.
This versatility puts the transmitter at home in a variety of applications from video production, theater, stage and house of worship.
Frequencies are selectable in 100kHz or 25kHz steps across a maximum tuning range of 76.7MHz. This yields a total of 3,072 available frequencies across three standard frequency blocks. The tuning range varies in other blocks to meet applicable frequency allocations.
The servo bias input accepts mic or line level signals with a wide range of gain adjustment in 1dB steps. Accurate LED indications on the top panel and a bar graph indicator on the LCD allow precise gain adjustments to be made for the maximum signal-to-noise ratio and minimum distortion. The limiter in the preamp can cleanly handle signal peaks over 30dB above full modulation, allowing the input gain to be set high enough to achieve the maximum signal-to-noise ratio.
Compatibility with earlier analog Lectrosonics receivers, Lectrosonics IFB receivers and some receivers from other manufacturers is provided by DSP emulation modes selected in the LCD menu.
The housing is an aluminum extrusion with machined aluminum top and control panels, finished with an ultra hard, black electroless nickel finish called ebENi. Spring contacts inside the compartment and nickel-plated contacts on the door keep the batteries from rattling and provide reliable electrical contacts. The unit is protected from reverse battery polarity electrically, and by the insulated contact plate in the battery door.
The membrane switch panel and LCD enable access to all adjustments and settings. The menu structure is easy to navigate. Battery status is indicated by a bi-color LED that is green with a fresh one, turns to red as it runs down, and then starts blinking red when there is 30 minutes of runtime left.
The Main Window displays the current settings - including frequency, battery status, RF output status, and audio level (modulation).
Digital Hybrid Wireless® Design - Digital Hybrid Wireless is a patented design that combines 24-bit digital audio with an analog FM radio link to provide outstanding audio quality and the extended operating range of analog wireless systems.
The design overcomes channel noise in a dramatically different way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link.
This proprietary algorithm is not a digital implementation of an analog compander. Instead, it is a technique which can be accomplished only in the digital domain, even though the audio inputs and outputs are analog signals.

Great transmitter. Our sound guy loves them.
