Lectrosonics UCR411a Overview

The Lectrosonics UCR411a Wireless Lavalier Microphone System Kit with No Mic from B&H delivers Lectrosonics's world-renowned, pristine wireless audio and reliability for professional field & location production.


The kit comes with the SMV super-miniature bodypack transmitter and the UCR411a SmartDiversity wireless receiver. The transmitter features a water-resistant, super-hard finish and includes a mic-connector kit with a weather resistant sleeve.

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

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

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 SMV Super Miniature Wireless Microphone Transmitter (Freq Block 21)

The Lectrosonics SMV Super Miniature Wireless Microphone Transmitter incorporates Lectrosonics patented Digital Hybrid Wireless technology, in a package no bigger than a pager. The SMV transmitter is miniature in size yet rugged enough to withstand rigorous daily use in the field or in studios.

To meet the demand for both extended operating range and extended battery life, the SMV transmitters offer selectable output power of 50, 100 or 250 mW. A third selection at 50 mW is provided for some theatrical applications, where the system design specifies lower transmitter power. The SMV transmitter offers 256 user-selectable UHF frequencies. The Switchcraft TA5M audio input has user-calibrated 44 dB gain range, and accepts electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB and a dual-release envelope, making the limiter transparent while maintaining low distortion.

Lectrosonics patented Digital Hybrid technology revolutionizes wireless microphone transmission. Digital audio signal is converted and encoded for analog transmission, then decoded and converted back to digital audio at the receiver. The result is an exceptionally low noise floor as the compandor circuit is eliminated and clear audio reception is retained at greater distances.

The non-corrosive, machined aluminum casing is splash proof and features an LCD display with membrane switch control panel. The transmitter is powered by one AA lithium, NiMH or alkaline battery for up to 7.25 hours (lithium). The SMV transmitter is completely compatible with all Lectrosonics Digital Hybrid wireless receivers, as well as older Lectrosonics analog receivers.

Variable, Selectable Output Power

The SMV features selectable 50, 100 or 250 mW output power.

Miniature Design

The miniature design allows for a variety of mounting possibilities in film, video, theater, performances, etc.

Digital Hybrid Wireless Architecture

Lectrosonics incorporates digital and analog audio technology to enhance range and eliminate the noise associated with compandor circuits.

Locking TA5-Male Connection

A locking TA5M input is compatible with Lectrosonics and third-party microphones and cables. The input accepts line and microphone level signal.

Backwards Compatibility

The SMV transmitter is completely compatible with all current Lectrosonics Digital Hybrid receivers and older Lectrosonics analog receiver models as well.

Splash-Proof Enclosure

The polished aluminum enclosure is moisture proof and ideal for use in rain.

Extended Battery Life

The SMV transmitter is powered by one AA alkaline, NiMH or lithium rechargeable battery. With Lithium power, the unit is capable of up to 7.25 hours of use.
