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.
