The Lectrosonics DCR822 Compact Dual-Channel Digital Wireless Receiver compact 2-channel digital receiver with analog and digital audio outputs utilizes the Lectrosonics signature digital architecture with remarkable audio quality and ultra-low latency. The Lectrosonics DCR822 CompactWireless Receiver includes an extended operating range rivaling the best analog and Digital Hybrid Wireless® systems with continuously tunable tracking filters covering the entire frequency band of the unit. The innovative Vector Diversity technology raises the bar for digital transmission integrity with two RF front ends per channel, and a unique phase-matching system. The extremely robust RF front ends of the receiver will hold up in severe RF environments and close carrier spacing, whether analog or digital. The DCR822 Dual-Channel Wireless Receiver has a flexible output routing scheme, allowing a variety of applications including Talkback. And, a digital recorder at 24 bits, 48 kHz is included – and records up to 4 audio tracks on a front-mounted microSD card.
The DCR822 receiver is compatible with pure digital transmitters from the D Squared line including the DBSM, DBSMD, DBu, DHu, DPR and DPR-A. The 822 is also compatible with stereo digital transmitters including the DCHT and M2T. Finally, the receiver is also backward compatible with any Digital Hybrid Wireless transmitter made in the last 20 years.
Vector Diversity for Mission-Critical Performance
The DCR822’s Vector Diversity subsystem smoothly and continuously combines RF signals from two receiver front ends per channel, with differing phase angles in order to obtain maximum energy. Not only does this method deliver clean, artifact-free performance in all modes, it is actually able to take two signals compromised by multipath interference and reassemble them into a usable signal.
High IP3 Performance for Tough RF Environments
The DCR822 has one of the highest Third-Order (IP3) Performance of +15 dBm, comparing this with +5 to +8 dBm provided by typical audio RF transmitters. High IP3 performance allows the DCR822 to better eliminate the negative impact caused by third-order intermodulation artifacts, have better signal-to-noise ratio, and also perform greater reliability in today's congested RF spectrum.
SmartNR Noise Reduction
With a noise floor at -120 dBV and a frequency response up to 20 kHz, high-frequency noise in the source audio is more apparent than in conventional wireless systems. The SmartNR algorithm has three modes. When OFF, no noise reduction is performed. When NORMAL is selected, enough noise reduction is applied to remove most of the hiss from the mic preamp and some of the hiss from lavaliere microphones. When FULL is selected, enough noise reduction is applied to remove most of the hiss from nearly any signal source of reasonable quality, assuming levels are set correctly at the transmitter.
SmartTune Auto Frequency Selection
A major problem facing wireless users is finding clear operating frequencies, especially in RF saturated environments. SmartTune solves this problem by automatically scanning all the frequencies available in the unit, and tuning to the frequency with the lowest RF interference, significantly reducing setup time.
Onboard Recording via microSDHC Card
The DCR822 can record received audio on a microSD card, in the industry-standard .wav (BWF) file format, at 24-bit/48 kHz for compatibility with any audio or video editing software. Recording can be done simultaneously with audio output from the receivers. You can record up to 46 hours on a 32GB card.
The DCR822 offers compatibility with the D-Squared and Duet digital transmitters, including the DBu, DHu, DPr, DCHT, and M2T. There is backward compatibility with any Digital Hybrid wireless transmitters including the SM and SMWB series, WM, HM Series, MM400 Series, HHSeries, LT, LMb, UM400 Series, and SSM.
