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 UM400 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 a pair of AA batteries or an external DC power supply.

The Lectrosonics UM400 is a UHF body-pack transmitter. The transmitter features 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. A TA5-male input is compatible with any microphone or cable featuring a TA5 connection. The input level is variable, allowing use with low impedance mics, electret lavalier mics with positive or negative bias 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 resulting in greater operating range without noise and artifacts caused by analog compandor circuits.
Compact Design
The UCR401 and UM400 feature 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 and UM400 are powered with two AA alkaline or lithium batteries. The receiver will operate up to 11 hours on lithium, 4hours (continuous) with alkaline batteries.
256 Selectable Frequencies
Both transmitter and receiver offer 256 selectable UHF frequencies over a 25.6MHz range.
Smart 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.
