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 VectorDiversity subsystem constructively combines all the energy available at bothantennas, smoothly and continuously combines RF signals from two receiver frontends per channel, with differing phase angles in order to obtain maximum energyand signal-to-noise.

Traditional “true diversity” or “ratio diversity” methodsuse two complete receivers and blend the audio. This works well for FM andDigital Hybrid systems but falls short of the ideal for today’s all-digitalmodes. The DCR822’s Vector Diversity subsystem deliver clean, artifact-freeperformance in all modes, and actually able to take two signals compromised bymultipath interference and reassemble them into a usable signal.

The DCR822features an all-digital audio path, 24bit/48kHz digital audio, which outputs to(2) analog audio signals or (4) AES3 digital audio signals (when used withstereo modes).

The DCR822 includes AES-256 CTR encryption with 4 types of keypolicies: only Lectrosonics provides such flexible and powerful encryption.

TheDCR822 also has on-board recording, in the industry standard .WAV (BWF) fileformat, allowing recording time of 46 hours with a 32GB microSDHD card.

Note: The dual envelope “soft” limiter

provides exceptionally good handling

of transients using variable attack and

release time constants. Once activated,

the limiter compresses 30+ dB of transmitter
