Excellent performance in a small package for ENG and DSLR video production is the purpose and intent of the LR receiver design. Tracking front-end filters block interference from high powered RF signals on nearby channels to preserve the extended operating range. RF spectrum scanning displays accurate results on the LCD to make finding clear spectrum quick and easy. The receiver is powered by internal AA batteries or with an optional battery eliminator. The top panel includes an IR port for transmitter setup. Firmware updates are enabled via a USB port on the side panel. The housing is made from a solid machined aluminum billet. 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.
