Audio-Technica ATWR1820D
The ATW-R1820 is the dual-channel receiver at the heart of Audio-Technica's 1800 Series, packing two independent True Diversity receiver sections into one compact chassis so a single unit handles two wireless mics. Each section scans 996 UHF frequencies in 25 kHz steps and locks on with digital Tone Lock squelch, while a backlit LCD with soft-touch controls handles setup and level monitoring.
Each channel outputs a balanced signal on a 3-pin mini XLR (TA3M) connector, and one internal receiver can be switched off to stretch battery life when only one channel is needed. It runs on six AA batteries or a 12V DC supply and pairs with the ATW-T1801 body-pack and ATW-T1802 plug-on transmitters. Offered in Band C (ATW-R1820C) and Band D (ATW-R1820D); this receiver is discontinued.
