Bose Professional ControlSpace ESP-880A – 8x8 Open-Architecture DSP Processor Product Overview The Bose Professional ControlSpace ESP-880A is a rack-mount, open-architecture DSP en gineered sound processor designed for installed commercial audio systems ranging from single-room configurations to large multi-zone networked installations. It provides 8 balanced analog inputs and 8 balanced analog outputs at 48 kHz/24-bit with 115 dB dynamic range and 860 microsecond analog-to-analog latency — specifications that meet the demands of live reinforcement, conference room DSP processing, and broadcast applications alike. An 8-channel AmpLink output port delivers uncompressed digital audio to compatible Bose Professional amplifiers over standard Cat 5 cable, while onboard RS-232, five control inputs, and five control outputs enable integration with Crestron, AMX, and Bose ControlCenter zone controllers. Configured entirely through Bose ControlSpace Designer software, the ESP-880A is the signal-processing backbone for demanding commercial AV integration projects. Product Description The ESP-880A occupies a single rack space (1U) at 1.7 in × 19.0 in × 8.5 in and weighs 5.7 lb — a compact footprint relative to its processing capability. The processor's floating-point, open-architecture DSP delivers 3.6 GIPS / 2.7 GFLOPS of processing power, driven by a 32-bit fixed/floating-point DSP alongside an Arm 456 MHz CPU. This headroom supports simultaneous deployment of complex signal chains including automatic mic mixing, predictive feedback suppression, room combining, and multiband EQ across all eight channels without audible artifacts. All eight analog inputs accept mic or line-level signals with selectable gain from 0 dB to +64 dB and per-channel 48V phantom power, making the ESP-880A suitable for systems that combine condenser microphones, program sources, and paging inputs on a single processor. The eight analog outputs deliver up to +24 dBu at 66 Ω output impedance. The AmpLink output port sends up to eight channels of low-latency digital audio directly to compatible Bose Professional PowerShare and PowerMatch amplifiers, eliminating analog cabling between the rack processor and amp frames. Control connectivity is comprehensive: a rear-panel RJ-45 Ethernet port (100 Mbps) handles both software configuration and real-time network control; an RS-232 DB9 port enables third-party serial integration; five general-purpose control inputs (0–3.3V analog or digital, 5V maximum) accept signals from switches and potentiometers; and five digital control outputs (10 mA source, 100 mA sink) drive external devices. A dedicated CC-16 port connects Bose ControlCenter CC-16 zone controllers directly. The unit draws under 37 VA typical and dissipates 22W, fitting within tight equipment room power budgets. Mains voltage range is 85–264 VAC, 50/60 Hz. Bose Professional's 5-year commercial warranty applies. Key Features 8 × 8 Analog I/O — Eight balanced mic/line inputs and eight balanced line outputs on 6-pin Euroblock connectors, with +24 dBu maximum level on both input and output. 115 dB Dynamic Range — A-weighted dynamic range across the analog signal path ensures audible noise floor is well below the threshold of perception in any installed environment. Ultra-Low Latency DSP — 860 microsecond analog-to-analog latency enables the ESP-880A in systems with strict lip-sync and reinforcement timing requirements. Floating-Point Open-Architecture DSP — 32-bit fixed/floating-point DSP with Arm 456 MHz CPU delivers 3.6 GIPS processing power for complex, multi-channel signal chains. AmpLink Digital Output — 8-channel AmpLink port transmits uncompressed digital audio over Cat 5 to compatible Bose Professional amplifiers, replacing analog amp-feed cabling. Per-Input 48V Phantom Power — Selectable phantom power on each of the eight inputs accommodates condenser microphones alongside line-level sources in the same I/O frame. Comprehensive ControlSpace Designer Support — Full access to automatic mic mixers, predictive feedback suppressors, room combiners, AGCs, duckers, gates, compressors, delays, graphic/parametric EQs, and Bose loudspeaker libraries. Third-Party Control Integration — RS-232 and Serial-over-Ethernet protocols with available Crestron and AMX driver files; compatible with full ControlSpace Remote mobile control. Five GPIO In / Five GPIO Out — Analog or digital control inputs and digital control outputs for trigger-based automation and external device control without a third-party controller. 1U Rack-Mount Form Factor — 1.7 in × 19.0 in × 8.5 in; 5.7 lb; active side-venting cooling; standard rack ears included. Universal Mains Input — 85–264 VAC, 50/60 Hz; under 37 VA typical consumption; IEC C14 inlet. 5-Year Manufacturer Warranty — Commercial-grade warranty coverage from Bose Professional.

The ESP-880A provides 8 × 8 analog I/O plus AmpLink output. The ESP-880AD adds 32 × 32 Dante network audio I/O to the same analog and AmpLink I/O. If your installation uses Dante network audio for routing between components, the ESP-880AD is the appropriate choice. The ESP-880A is well suited for installations using only analog sources and AmpLink-connected amplifiers. What DSP modules are available in ControlSpace Designer for the ESP-880A? ControlSpace Designer provides a comprehensive library including: automatic mic mixers, predictive feedback suppressors, room combiners, multiband graphic and parametric EQs, Bose loudspeaker EQ libraries, signal generators, routers, matrix mixers, AGCs, duckers, gates, compressors, source selectors, and delays up to 43 seconds. All modules are drag-and-drop and can be interconnected visually within the software design canvas. Can the ESP-880A integrate with Crestron or AMX control systems? Yes. The ESP-880A supports full serial control via RS-232 and Serial-over-Ethernet, and Bose Professional provides driver files for both Crestron and AMX platforms. All signal processing modules, parameter sets, and groups are directly addressable by third-party control systems. This makes the ESP-880A a standard choice for AV integration projects in government spaces, conference rooms, and commercial meeting spaces that already use Crestron or AMX. How many microphone inputs does the ESP-880A support, and does it provide phantom power? All eight analog inputs accept microphone-level signals with gain settings up to +64 dB. Phantom power (48 VDC, 10 mA) is selectable per input, so condenser microphones and line-level sources can coexist on the same unit. Equivalent input noise is < -119 dBu at maximum gain with a 150 Ω source — low enough for sensitive conference room microphone applications. What Bose Professional amplifiers are compatible with the AmpLink output? The AmpLink output is compatible with Bose Professional PowerMatch and PowerShare amplifiers that include an AmpLink input. AmpLink transmits up to 8 channels of uncompressed, low-latency digital audio over a single Cat 5 cable, eliminating the analog snake between the processor rack and amp frame. For a complete system recommendation, contact Creation Networks. Does the ESP-880A support remote monitoring and control? Yes. ControlSpace networked systems support remote monitoring and control through ControlSpace Designer software and ControlSpace Remote (mobile-ready end-user control). The unit can be accessed over the facility network using its Ethernet port, and automation events can be scheduled or triggered via GPIO inputs. Remote access capabilities are fully documented in the ControlSpace Designer software. What is the warranty and support arrangement for the ESP-880A? The ControlSpace ESP-880A carries a 5-year Bose Professional manufacturer's warranty. Creation Networks provides pre-sales consultation, system design support, and post-sale warranty coordination.
