The LT transmitter offers a full set of professional features in a compact, rugged package. The unit is compatible with all Digital Hybrid Wireless receivers and even some from other manufacturers, making it comfortable in a wide variety of applications from video production to theater, stage and house of worship.

The LT 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.

Frequencies are selectable in 100 kHz or 25 kHz steps, yielding a total of up to 3072 available frequencies across three standard frequency blocks.* An IR port on the membrane panel enables automatic setup when coupled with an IR enabled receiver. A USB port on the side panel allows firmware updates to be made easily. The servo bias input accepts mic or line level signals with a wide range of gain adjustment in 1 dB steps. A menu selectable instrument level input is available on the LCD. 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 30 dB above full modulation, allowing the input gain to be set high enough to achieve the maximum signal to noise ratio with no risk of overload distortion. The unit is powered by two AA batteries or an optional battery eliminator that replaces the hinged battery door. A wire and a spring loaded belt are available.

The housing is machined from a solid aluminum billet, finished with an ultra hard, black electroless nickel finish called ebENi.3

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 the finest 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 compandor. Instead, it is a technique which can be accomplished only in the digital domain, even though the audio inputs and outputs are analog signals
