Lectrosonics UCR411A overview

  • 1Description

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.

Note: For system compatibility, the component's frequency must match your existing system/component frequency.

Digital Hybrid Technology
24-bit digital audio stream is decoded at the receiver resulting in greater operating range without noise and artifacts caused by analog compandor circuits.
256 Selectable Frequencies
The receiver offers 256 selectable UHF frequencies over a 25.6 MHz range.
SmartDiversity Diversity Reception
The UCR411 uses Lectrosonic's SmartDiversity design analyzes incoming audio signal to determine the optimum timing for phase switching. The result is minimal noise and dropout due to RF interference.
SmartNR
Lectrosonics SmartNR (Noise Reduction) automatically allocates noise reduction by attenuating audio signal that match a calculated, statistical profile. The result enhances clarity and intelligibility while eliminating noise.

    Lectrosonics UCR411A reviews

    UCR411A - Wireless Diversity Receiver is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Awesome but expensive product! I work in a reality TV and live event world and there is no room for mic interference and signal loss so this Lectrosonics diversity receiver and Lavalier transmitter was the answer to all my troubles! I had been using Sennheiser wireless lavs which are analog mics and was constantly getting noise and interference and the occasional Spanish radio station! But with this system it's crystal clear sound even if the actors are far away from the receiver. It's expensive but for me and my everyday audio demands it was worth it!

    Rated 5 out of 5 by from Outstanding As Always I'm a professional ENG/EFP mixer and for talent I use Lectrosonics exclusively...quick scanning for best available frequency is invaluable and rock solid.
