Lectrosonics DCR822 Compact Dual-Channel Digital Receiver

Built for bags and carts, the Lectrosonics DCR822 compact dual-channel digital receiver runs on four AA batteries or external DC and records what it receives.

It has the same cross-section as the older UCR411A, so existing mounting hardware fits. The machined aluminum housing has a hard-anodized finish with laser-etched markings, and settings are made from the front panel with tactile buttons and a bright OLED display.

Frequency Bands

Trew Audio carries the A1B1 version (470.100 to 614.375 MHz) and the 941 version (941.525 to 959.825 MHz). Frequencies step in 25 kHz increments, and each version comes with jointed SMA antennas for its range.

Vector Diversity

Each channel has two RF front ends, and Vector Diversity blends their signals continuously at differing phase angles to capture the most signal energy. It can even rebuild a usable signal from two signals damaged by multipath. High-current front ends with an IP3 of +15 dBm hold up in severe RF and with close carrier spacing.

Outputs and Recording

Two rear TA3M jacks carry analog or AES3 digital audio. Their level adjusts from -50 to +5 dBu in 1 dB steps, and in the modes that support it, the routing includes TalkBack. The front microSD slot records up to four tracks of 24-bit, 48 kHz BWF audio. Latency is 1.4 ms from a digital transmitter, and SmartNR noise reduction clears hiss from lav mics and preamps in its Normal and Full settings.

The DCR822 receives Lectrosonics D-Squared and Duet digital transmitters, with AES 256 CTR encryption, and any Digital Hybrid Wireless transmitter made in the last 20 years. The Compatibility tab lists them by name.
