รหัสสินค้า : BOSE-EX-440C

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.

Features

• All-in-one design supports simultaneous VoIP, PSTN, and USB soft codecs in a single, 1RU model
• 8-channel advanced AEC with multiple references, routable to both analog and Dante inputs
• Adaptable noise cancellation on each AEC channel; non-linear processing and comfort noise to enhance the clarity and intelligibility of meetings
• Single-line VoIP with an internal web interface, allowing IT personnel to configure VoIP parameters without design file access or integrator involvement
• PSTN (RJ-11) connection for worldwide POTS/analog telephone systems
• USB connection facilitates easy integration with all soft codecs
• Dante audio networking includes 16 × 16 audio channels for connection to other Dante-enabled products, including native Dante-integrated microphones and amplifiers
• AmpLink port provides 4 channels of uncompressed, low-latency digital audio to AmpLink-equipped Bose Professional amplifiers

Applications

Designed for a wide range of applications, including:

• Small/medium conference rooms
• Courtrooms
• Distance learning
