Free your computer-based recording or livestreaming rig from the constraints of cables and complicated set up with the Convergent Design Erika-4, a four-person USB wireless microphone system that's ultracompact, extremely simple, and cost-effective, making it ideal for content creators, podcasters, mobile journalists, and educators as well as corporate meeting hosts and participants. The system comprises a miniature USB receiver with a stand, two equally tiny transmitters (two black and two white) equipped with built-in omni microphones, and a hard case for safe storage and transport.
Each mic/transmitter unit features a USB-rechargeable battery and a convenient magnetic attachment method, allowing it to be used as a lavalier mic or a table mic. Automatic pairing and channel selection allow you start working without having to read a manual or dig through menus. Auto gain control with an integrated limiter ensures optimal audio levels free of hassle, and the transmission power is adjustable to optimize battery life (24 hours with the default setting) or range (300' max). When using multiple mics with the receiver, the system's dynamic mic switching ensures that only one mic is heard at a time, significantly reducing overall noise. The Erika app provides special functions such as naming mics, locking to a particular mic, accepting more users, and more.
Beyond supporting multiple mics to one receiver, dynamic switching blocks the noise, combing, and echoes from "open" mics, while dramatically reducing the wireless traffic compared to analog wireless mics.
