Lectrosonics UCR411A Digital Hybrid Receiver – Block 20

Description

The Lectrosonics UCR411A UHF receiver provides professional performance and a versatile feature set in a compact design for field and location production. All settings are made from the front panel with a powerful LCD interface, making the unit ideal for use in Quad Paks, on sound carts, in portable bags and in rack mount multi-couplers. To alleviate interference problems in an increasingly congested RF spectrum, an RF spectrum analyzer is built into the receiver. The receiver tunes across its 25.6 MHz tuning range and records RF activity with markers on the LCD screen. Finding clear operating frequencies is a quick, simple process. The UCR411A is compatible with all 400 Series Lectrosonics wireless transmitters (and some other transmitter types) and can be powered with internal 9V batteries or external DC. This receiver includes compatibility modes which enable it to operate with many other Lectrosonics products including analogue transmitters. Transmitter choices include the UM, SM, SMD or SMQ.

The mechanical design of the receiver combines field proven features developed over many years of experience in motion picture and television production markets. The machined aluminum housing and panels are surfaced with electrostatic powder coated and anodized finishes with laser etched markings to withstand the rigors of field production.

Digital Hybrid Wireless®(U.S. Patent #7,225,135)

Digital Hybrid Wireless® is a revolutionary new design that combines 24-bit digital audio with an analog FM radio link to provide outstanding audio quality and the extended operating range of the best analog wireless systems.

The design overcomes channel noise in a dramatically new way, digitally encoding the audio bitstream in the transmitter and decoding it in the receiver, yet sending the encoded information via an analog FM wireless link. This proprietary DSP algorithm eliminates a compandor circuit and its artifacts, and preserves the RF spectral footprint of analog FM designs to simplify multi-channel coordination with exisiting analog wireless systems.
