Description

Description

The EX-1280 serves as a centralized brain for sound systems, offering a flexible platform that integrates seamlessly with Bose loudspeakers, wall controllers, and third-party Dante-enabled devices. Its open-architecture design allows system integrators to use ControlSpace Designer software for drag-and-drop programming of signal processing modules, making it suitable for both small projects and large, networked systems. 

Key Features

  • Flexible I/O Configuration: Features 12 balanced mic/line analog inputs and 8 analog outputs.
  • High-Capacity Dante Networking: Equipped with a 64 × 64 Dante network audio interface for low-latency digital audio across large networks.
  • AmpLink Output: Includes a dedicated port for 8 channels of uncompressed, low-latency digital audio directly to compatible Bose Professional amplifiers.
  • Front-Panel Control: A large 256 × 64 OLED display and rotary encoder allow for monitoring channel activity and configuring network parameters directly from the hardware.
  • Advanced Control Options: Supports GPIO (5 in/5 out) for external interfaces such as microphone pushbuttons or status LEDs, alongside serial RS-232 and RS-485 connections.

Applications

The EX-1280 is optimized for a variety of commercial and professional environments, including:
  • Performance Venues and Stadiums: For large-scale sound reinforcement and complex routing.
  • Houses of Worship: To manage multiple zones and high-quality mic inputs.
  • Hospitality and Resorts: For multi-zone background and foreground music distribution.
  • Corporate Multipurpose Spaces: Handling varied audio needs across divisible rooms.
  • Courtrooms: Where reliable, secure audio routing and local voice lift are essential.
