Bose Professional ControlSpace EX-440C Conferencing Sound Processor

Bose Professional ControlSpace EX-440C is a conferencing sound processor designed for small- to medium-size meeting environments. It enables microphone integration, signal processing, and system connectivity for integrators and AV designers, supporting conferencing and collaboration workflows. This makes it ideal for rooms where integrated audio processing and flexible connectivity are required.

The processor operates as an all-in-one platform with analog, digital, VoIP, PSTN, USB, Dante, and AmpLink connectivity. It includes onboard acoustic echo cancellation and DSP to manage conferencing audio paths and routing. Configuration and control are performed through ControlSpace Designer software.

The system supports applications that require centralized conferencing audio control and networked audio integration. It is suited for conference rooms, courtrooms, and distance learning environments. The design allows integration with compatible Bose Professional amplifiers, microphones, and networked audio systems.

Key Features

• All-in-one conferencing processor: Supports VoIP, PSTN, and USB soft codecs in a single 1RU unit
• Eight-channel AEC: Provides acoustic echo cancellation with multiple references
• Dante audio networking: Includes 16 × 16 Dante channels for networked audio integration
• AmpLink connectivity: Provides four channels of digital audio to AmpLink-equipped amplifiers
• Software-based configuration: Uses ControlSpace Designer for drag-and-drop system setup
