Bose 772234-1110 ControlSpace EX-1280C – Conferencing DSP Processor with AEC

Product Overview

The Bose ControlSpace EX-1280C is a 1RU conferencing sound processor designed for large conference rooms, boardrooms, and multi-room collaboration spaces that require full AEC, VoIP, PSTN, and Dante audio networking in a single rack-mount unit. With 12 mic/line analog inputs, 8 analog outputs, 8-channel AmpLink digital output, 12-channel acoustic echo cancellation (AEC), and 64x64 Dante connectivity, the EX-1280C provides the signal processing infrastructure for complex unified communications deployments. Its open-architecture DSP platform is configured through Bose ControlSpace Designer software, making it compatible with AMX, Crestron, and other industry-standard control systems used in commercial AV integration. The EX-1280C supports simultaneous VoIP, PSTN, and USB soft codec connections — covering the full range of communication platforms in a single device.

Product Description

The EX-1280C is the highest-capacity model in Bose's ControlSpace EX conferencing processor line, built for installations where a single processor needs to handle multiple rooms or a large single space with demanding AEC, telephony, and distributed audio requirements. Its 12-channel AEC engine is routable to both analog and Dante inputs, allowing integrators to place microphones anywhere in a Dante network and still apply full acoustic echo cancellation — a key advantage in distributed or large-room conference environments.

The two SIP 2.0-compliant VoIP lines include a built-in web interface for IT configuration, which allows network administrators to set VoIP parameters without accessing the ControlSpace Designer design file — a significant advantage in enterprise deployments where IT and AV teams manage systems independently. A single PSTN line (RJ-11) provides analog telephone fallback for regions and facilities that require it. The Micro-USB device port enables PC-based soft codec connections with stereo audio in and out, satisfying Zoom, Teams, WebEx, and similar platforms.

The EX-1280C's 32-bit fixed/floating-point DSP at 456 MHz, coupled with an ARM Cortex-A8 CPU at 600 MHz, supports up to 3.6 GIPS and 2.7 GFLOPS of processing. Total channel capacity is 166 I/O channels across all connection types: 20 analog (12 in, 8 out), 8 AmpLink outputs, 64x64 Dante, 4 VoIP, 4 USB, and 2 PSTN. The 256x64 OLED display and rotary encoder on the front panel allow IP address setup and channel metering without a connected PC.

GPIO (5 in/5 out) enables integration with room scheduling panels, occupancy sensors, and fire alarm relays. RS-232 and RS-485 (CC-16) serial ports support Bose wall controllers and third-party control systems. Two Ethernet ports support ControlSpace and Dante with primary/secondary redundant configurations.

Available from Creation Networks as SKU 772234-1110 (US-120V).

Frequently Asked Questions

How many AEC channels does the EX-1280C provide, and can they be shared across rooms?

The EX-1280C provides 12 AEC channels. Multiple rooms can share the processor — the AEC channels are routable to both analog inputs and Dante network inputs, enabling a single EX-1280C to serve several spaces in a distributed conferencing design. Multiple EX-1280C processors can also share AEC references.

Can the EX-1280C's VoIP lines be configured without access to the ControlSpace Designer file?

Yes. Both VoIP lines include an internal web interface that IT personnel can access directly via a browser to configure SIP 2.0 parameters — extension, server address, credentials, and dial plan — without requiring the AV integrator's design file or ControlSpace Designer software.

What soft codecs does the USB port support?

The Micro-B USB port presents as a standard USB audio device, making it compatible with any PC-based soft codec that uses system audio: Zoom, Microsoft Teams, Cisco WebEx, GoToMeeting, and others. No additional drivers are required on most operating systems.

How does the EX-1280C connect to Bose Professional amplifiers?

The AmpLink output delivers 8 channels of uncompressed, low-latency (<21 μs) digital audio to AmpLink-equipped Bose Professional amplifiers (PowerMatch, PowerShare series) over a single shielded Cat 5/6 cable, eliminating the need for analog cable runs from the processor rack to amplifier racks.

Is the EX-1280C compatible with AMX and Crestron control systems?

Yes. The EX-1280C supports RS-232, RS-485, and Ethernet control interfaces. Bose provides drivers for AMX and Crestron platforms. ControlSpace Designer software also generates control API documentation for third-party integrations.

What is the difference between the EX-1280C and the EX-1280?

The EX-1280 (SKU 834317-1110) is a general-purpose DSP platform with 12 analog inputs, 8 analog outputs, and 64x64 Dante, but without AEC, VoIP, or PSTN telephony. The EX-1280C adds 12-channel AEC, 2 VoIP lines, and a PSTN line for dedicated conferencing applications.

What is the warranty on the Bose ControlSpace EX-1280C?

Bose Professional products are covered by Bose's standard commercial warranty. Contact Creation Networks for current warranty terms and authorized service options in your region.
