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 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 LEDs 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.
