Bose Professional ControlSpace EX-1280 Digital Signal Processor

Bose Professional ControlSpace EX-1280 is a digital signal processor designed for general-purpose and installed sound applications. It enables flexible audio routing and signal processing for system designers and integrators, supporting PA and sound system control workflows. This makes it ideal for venues where scalable processing and networked audio connectivity are required.

The processor operates in a single-rack-unit format with open-architecture DSP and extensive analog and digital I/O. It supports Dante audio networking and AmpLink connectivity for integration with compatible Bose Professional amplifiers. Configuration and control are performed using ControlSpace Designer software.

The system supports applications that require centralized audio processing across multiple zones and sources. It is suited for performance venues, houses of worship, hospitality spaces, and courtrooms. The design allows integration with a wide range of Dante-enabled and analog audio devices.

Key Features

• Open-architecture DSP: Designed for general-purpose audio processing and PA applications
• High-density I/O: Provides twelve mic/line inputs and eight analog outputs
• Dante audio networking: Supports 64 × 64 channels for large-scale networked audio systems
• AmpLink output: Delivers eight channels of uncompressed digital audio to compatible amplifiers
• Rack-mount form factor: Single 1RU chassis with front-panel display and controls
