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.
O fluxo de áudio digital de 24 bits é decodificado no receptor, resultando em um alcance operacional maior sem ruídos nem artefatos causados por circuitos compandor analógicos.

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.
SmartNR
O SmartNR (Redução de Ruído) da Lectrosonics aloca automaticamente a redução de ruído atenuando o sinal de áudio que se adequa a um perfil estatístico calculado. O resultado aprimora a clareza e a inteligibilidade eliminando o ruído.
