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 includes the UCR411A camera mountable receiver and HM Digital Hybrid plug-in transmitter.

The UCR411A is a 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 clear frequencies are marked and displayed on the backlit LCD. Balanced XLR output provides maximum output gain with minimal noise and the receiver is powered with internal 9V batteries or external DC power supply.

The HM Digital Hybrid Plug-in Transmitter is a UHF transmitter with 256 user selectable UHF frequencies and digital hybrid signal transmission for optimum range while minimizing noise. Incoming audio signal is digitized at 24-bit resolution, eliminating the noise and artifacts associated with analog compandors. The result is greater range with minimal noise. Its XLR input is compatible with any microphone or cable featuring an XLR connection. The input level is variable, allowing use with low impedance mics and line level devices. The receiver features a comprehensive LCD and low cut filter. A full 100mW output power is achieved on a single 9V battery.

• 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.

• 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

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.
