UCR411a Digital Hybrid Wireless Compact Receiver (Block 21: 537 to 563 MHz)

Product Description

The UCR411a Digital Hybrid Wireless Compact Receiver from Lectrosonics is a portable, camera mountable receiver designed for professional outdoor or indoor audio applications. It can be used when paired with a transmitter and microphone to capture audio for ENG (electronic news gathering), and EFP (electronic field production) functions, and more.

All settings are made from the front panel with an LCD interface, making the unit ideal for use in Quad Paks, on sound carts, in portable bags, and in rackmount multi-couplers. The receiver is compatible with all 400 series wireless transmitters and provides 256 selectable UHF frequencies across a 25.6 MHz tuning range. SmartDiversity reception reduces RF interference and dropout and a built-in RF spectrum analyzer searches across the entire 25.6 MHz tuning range, locating the strongest possible frequencies in the area.

Furthermore, a balanced XLR output provides maximum output gain with minimal noise and the receiver is powered by two internal 9V batteries or external DC power supply. The machined aluminum housing and panels are surfaced with electrostatic powder-coated and anodized finishes with laser etched markings to withstand the rigors of field production.
