Overview
  • 1Description

The Lectrosonics 400 Series wireless microphone systems combine digital hybrid technology, diversity reception and rugged components to achieve pristine audio signals at long range. This system is configured with the UCR401 camera mountable compact receiver and LM body pack.

The Lectrosonics UCR401 is a compact, portable camera mountable receiver designed for professional audio applications in the field or indoors. The receiver is completely compatible with all 400 series wireless transmitters and provides 256 selectable UHF frequencies across a 25.6MHz tuning range. Smart Diversity reception reduces RF interference and dropout and a built-in RF spectrum analyzer searches across the entire 25.6MHz tuning range, locating the strongest possible frequencies in the area. The transmitter is powered with internal 9V batteries or an external DC power supply.

The Lectrosonics LM transmitter features Digital Wireless Hybrid technology which combines a 24-bit digital audio chain with an FM radio link. The transmitter's digital signal path eliminates the need for an analog compandor, resulting in pristine, noise free audio fidelity throughout. Internal DSP provides compandor emulation so that the unit can be switched for use with 100, 200 and 400 series Lectrosonic receivers. The input section features a tap suitable for any microphone or line level audio source. 0 / -20dB LED's are provided for accurate level settings, and an "Audio Level" dial is located on the top face of the unit. Two rotary frequency adjust dials are located on the side panel. The 1.6MHz is a coarse adjustment and the 100kHz is the fine. The unit is powered via 9V battery and is enclosed in a rugged metal enclosure, made to withstand the rigors of road use.

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.
Compact Design
The UCR401 and LM transmitter feature a compact, lightweight design for enhanced comfort while mounted on cameras.
LCD & Spectrum Scanner
The comprehensive LCD provides all necessary parameter information as well as a frequency spectrum analyzer for locating ideal operating frequencies.
256 Selectable Frequencies
Both transmitter and receiver offer 256 selectable UHF frequencies over a 25.6MHz range.
SmartDiversity Diversity Reception
The UCR401 uses Lectrosonic's Smart Diversity design analyzes incoming audio signal in order 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.
