Lectrosonics DCR822 4-Channel Digital Receiver
Lectrosonics new portable digital 4-channel receiver DCR822 is the cornerstone of the new Lectrosonics digital system for field recording for screen production
The Lectrosonics DCR822 digital 2 channel receiver is the true successor to the venerable UCR411a – a dual-channel package in the same size - and represents state-of-the art RF performance with Vector Diversity (an advanced type of True Diversity) and extremely robust front-end architecture, bringing the Highest Level of RF and Audio Performance to Field and Location Production.
The DCR822’s powerful Vector Diversity subsystem constructively combines all the energy available at both antennas, smoothly and continuously combines RF signals from two receiver front ends per channel, with differing phase angles in order to obtain maximum energy and signal-to-noise. Traditional “true diversity” or “ratio diversity” methods use two complete receivers and blend the audio. This works well for FM and Digital Hybrid systems but falls short of the ideal for today’s all- digital modes. The DCR822’s Vector Diversity subsystem deliver clean, artifact-free performance in all modes, and actually able to take two signals compromised by multipath interference and reassemble them into a usable signal. The DCR822 features an all-digital audio path, 24bit/48kHz digital audio, which outputs to (2) analog audio signals or (4) AES3 digital audio signals (when used with stereo modes). The DCR822 includes AES-256 CTR encryption with 4 types of key policies: only Lectrosonics provides such flexible and powerful encryption. The DCR822 also has on-board recording, in the industry standard .WAV (BWF) file format, allowing recording time of 46 hours with a 32GB microSDHD card.
