Audio-Technica ATW-1821C
The ATW-1821 is a dual-channel lavalier system from Audio-Technica's 1800 Series, built on the ATW-R1820 receiver, which packs two independent receiver sections into one compact chassis. It ships with two ATW-T1801 UniPak body-pack transmitters and two lavalier microphones, so two presenters or performers can be miked at once from a single unit.
Each channel scans 996 UHF frequencies in 25 kHz steps, and up to ten 1800 Series systems can share a location. True Diversity reception and switchable 30/10 mW transmitter power keep both channels stable. Offered in Band C (ATW-1821C) and Band D (ATW-1821D). The ATW-1821 is discontinued; call for current availability.
