The Lectrosonics 400 Series wireless microphone system combines 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 HM plug-in transmitter.

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 external DC power supply.

The Lectrosonics HM/Back-lit LCD plug-in transmitter overcomes inherent channel noise with its patented hybrid technology, which digitally encodes the audio. A Lectrosonics digital hybrid receiver will decode the audio, giving the user all of the benefits of conventional FM wireless systems (range, resistance to interference, etc.) without the noisy artifacts introduced by analog compandors.

Digital Hybrid Technology
24-bit digital audio stream is decoded at the receiver end resulting in greater operating range without noise and artifacts caused by analog compandor circuits.
HM Plug-In Transmitter
The HM transmitter is capable of adapting standard XLR terminated microphones for wireless transmission. The HM transmitter is capable of supplying 48V phantom power to condenser microphones.
Compact Design
The UCR401 features a compact, lightweight design for enhanced comfort while mounted onto cameras.
LCD & Spectrum Scanner
The comprehensive LCD provides all necessary parameter information as well as a frequency spectrum analyzer for locating ideal operating frequencies.
Extended Battery Life
The UCR401 is powered with two AA alkaline or lithium batteries. The receiver will operate for up to 11 hours on lithium, 4 hours (continuous) with alkaline batteries.
256 Selectable Frequencies
Both transmitter and receiver offer 256 selectable UHF frequencies over a 25.6MHz range.
SmartDiversity Diversity Reception
The UCR411 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.
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.
