ControlSpace EX-440C conferencing sound processor
With an open-architecture, all-in-one design, the ControlSpace EX-440C conferencing processor facilitates high-quality microphone integration and audio processing for small- to medium-size conference rooms. Various inputs and outputs allow for flexible configuration: four mic/line analog inputs, four analog outputs, onboard VoIP, PSTN, USB, Bose Professional AmpLink output, eight-channel acoustic echo cancelling (AEC), and 16 × 16 Dante connectivity. ControlSpace Designer software simplifies the setup process with drag-and-drop programming, making configuration quick and easy.
