Lectrosonics DCR822 Quick Overview

Lectrosonics is no stranger to ENG Mixing Bags around the world, and the new DCR822 Receiver brings their signature digital architecture with remarkable audio quality and ultra-low latency into our world. It is a compact 2-channel digital receiver with analog and digital audio outputs. Because of its sleek and familiar form factor, a lot of Production Sound Mixers happy to add these receivers to their arsenal.

Unrivaled Quality

The DCR822 includes an extended operating range rivaling the best analog and Digital Hybrid Wireless® systems with continuously tunable tracking filters covering 470.100 – 614.375 MHz. 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 also has a flexible output routing scheme, allowing a variety of applications including Talkback.


The DCR822 has a built-in recorder, that is designed for use with microSDHC memory cards. The larger XC and UC cards use a different formatting method and bus structure and are NOT compatible with the recorder. ONLY microSDHC memory cards should be used.
