Lectrosonics LMB

The LMb transmitter 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 makes the transmitter at home in a wide variety of applications from video production to 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 3072 available frequencies across three standard frequency blocks. The tuning range varies in other blocks to meet applicable frequency allocations. "Digital Hybrid Wireless" combines 24-bit digital audio with an analog FM radio link to provide outstanding audio quality and the extended operating range of the best analog wireless systems. The design overcomes channel noise in a dramatically new way, digitally encoding the audio bitstream in the transmitter and decoding it in the receiver, yet sending the encoded information via an analog FM wireless link. This proprietary DSP algorithm eliminates a compandor circuit and its artifacts and preserves the RF spectral footprint of analog FM designs to simplify multi-channel coordination with exisiting analog wireless systems. FEATURES: • covers three standard frequency blocks • "Digital Hybrid Wireless" for compandor-free audio • 50mW RF power • compatibility modes for use with analog receivers • 25 or 100kHz tuning steps for up to 3072 selectable frequencies • integrated multi-function switch for mute or talkback modes • wide range input gain control in 1dB steps
