Product description

• Lectrosonics UCR411A Digital Hybrid Wireless Compact Receiver (Frequency Block 23) 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 HMa UHF Plug-On Wireless Transmitter (B1: 537.600 to 614.375 MHz) The HMa from Lectrosonics is a UHF plug-on transmitter that accepts mic or line-level signals via a standard XLR connector. It has selectable 5, 15, & 48V phantom power and can be used when paired with a Lectrosonics receiver and handheld microphone - sold separately - in applications for ENG (Electronic News Gathering), EFP (Electronic Field Productions), interviews for broadcast TV, and more. The input amplifier of the HMa transmitter uses an ultra-low noise op-amp for quiet operation and is gain controlled with a wide range dual envelope limiter. A 24-bit A to D converter digitizes the audio, and filters the supersonic noise above 21 kHz. The resulting signal is encoded with a proprietary algorithm to produce an analog data signal for RF transmission. Featuring a wide tuning range of 76 MHz, with tuning steps in increments of 100 kHz or 25 kHz for up to 3072 frequencies, the HMa transmitter also covers three standard 25.6 MHz Lectrosonics frequency blocks. Each block provides 256 different pilot tone frequencies. Legacy analog wireless microphone and IFB receivers are designed to work in DSP compatibility mode, as well as some receivers from other manufacturers. Finally, the transmitter is powered by two AA batteries, with status indicated by a multi-color LED. A USB port is also provided for firmware updates, and an IR (infrared) port is included to simplify setup with IR enabled receivers.
  • Digital Hybrid Wireless is a revolutionary design that combines digital audio with an analog FM radio link to provide outstanding audio quality and the exemplary RF performance of the finest analog wireless systems
  • Multi-color LED status indicator
  • Selectable 50/100 mW output power
  • 76 MHz tuning range in 100 kHz or 25 kHz steps for up to 3072 frequencies
  • The antenna is formed between the machined aluminum housing of the transmitter and the attached microphone or cable. It functions as a dipole radiator when attached to a hand-held microphone and somewhat like a ground plane antenna when connected with a cable or plugged directly into a mixer
