Bose ControlSpace ESP-880A engineered sound processor

Descriptions Bose ControlSpace ESP-880A engineered sound processor The Bose Professional ControlSpace ESP-880A is an open-architecture sound processor and designed for a wide variety of applications-for small, self-contained projects to large, networked systems. The Bose Professional ControlSpace ESP-880A features an 8x8 analog audio I/O, a Bose AmpLink output, and advanced digital signal processing with 48 kHz/24-bit audio conversion. The Bose Professional ControlSpace ESP-880A is engineered for precise performance and also has a features of low-latency and ultra-low noise operation. Bose Professional ControlSpace ESP-880A Main Features High-quality analog circuitry offers both mic and line-level I/O, operates with ultra-low noise and 115 dB dynamic range Advanced digital signal processing supports audio at 48 kHz sample rate/24-bit, uses a floating-point open architecture DSP and operates at low latencies for sound system precision Integrated AmpLink output connection uses standard CAT 5 cables to send up to 8 channels of low-latency, uncompressed digital audio to compatible Bose amplifiers Bose® ControlSpace® Designer software enables a large set of signal processing modules, such as automatic mic mixers, predictive feedback suppressors, room combiners, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGCs, duckers, gates, compressors, source selectors and delays A variety of control options – ControlSpace ESP products are compatible with programmable Bose CC-64 and CC-16 controllers, ControlCenter zone controllers and ControlSpace Remote clients. Supports industry-standard control systems using a comprehensive serial protocol through onboard RS-232 and Ethernet ports, with available drivers for AMX and Crestron-based systems APPLICATIONS Auditoriums Places of worship Resorts and hospitality venues Retail stores Educational institutions Specifications INTEGRATED DSP Signal Processor/CPU 32-bit fixed/floating-point DSP + ARM, 456 MHz Maximum Calculation 3.6 GIPS / 2.7 GFLOPS Delay 43 s Audio Latency 860 μs (analog in to analog out) A/D and D/A Converters 24-bit Sample Rate 48 kHz AUDIO PERFORMANCE SPECIFICATIONS Frequency Response 20 Hz - 20 kHz (+0.3 dB/-0.1 dB) THD+N < 0.002 % at +4 dBu (A-weighted/20 Hz – 20 kHz) Channel Separation (Crosstalk) < -105 dB at +4 dBu input and output level, 1 kHz Dynamic Range > 115 dB A-weighted 20 Hz – 20 kHz, analog through AUDIO INPUTS Input Channels 8 analog (balanced, mic/line level) Connectors, Input 3.81 mm Phoenix Contact®, 6-pin Input Impedance 12 kΩ @ 1 kHz (with or without phantom power active) Maximum Input Level +24 dBu Equivalent Input Noise <-119 dBu (22 - 20 kHz, 150 Ω input, 64 dB gain) Phantom Power +48 VDC, 10 mA, selectable per input Pre-Gain Settings 0/14/24/32/44/54/64 dB AUDIO OUTPUTS Output Channels 8 analog (balanced, line level), 8 AmpLink Connectors, Output 3.81 mm Phoenix Contact, 6-pin (analog), AmpLink RJ-45 Output Impedance 66 Ω Maximum Output Level +24 dBu CONTROL INPUTS Inputs (Control) 5 analog or digital inputs, 2 kΩ internal pull-up resistor to 5 V, 3.81 mm Phoenix Contact, 6-pin Analog Input Voltage Range 0 V to 3.3 V (maximum 5 V) Digital Input Voltage Range 0 V to 3.3 V (threshold voltage = 1.6 V) CONTROL OUTPUTS Outputs (Control) 5 digital outputs, 3.81 mm Phoenix Contact, 6-pin Output Voltage High: 8 V (open circuit), 2.5 V @ 10 mA; Low: < 1 V @ 100 mA, push-pull Output Current 10 mA source, 100 mA sink (24 VDC max external supply voltage) INDICATORS AND CONTROLS LED Status Indicators Power/Status, Signal, Ethernet, Serial (RS-232 + CC-16) Audio Signal Indication Green (-60 to -20 dBFS), Yellow (-20 to -2 dBFS), Red (-2 to 0 dBFS) ELECTRICAL SPECIFICATIONS Mains Voltage 85 VAC-264 VAC 50/60 Hz AC Power Consumption < 37 VA typical, over all mains voltages Mains Connector IEC 60320-C14 (inlet) Power Dissipation 22 W (75 BTU/hr, 19 kcal/hr) PHYSICAL Dimensions 1.7" H x 19.0" W x 8.5" D (44 mm x 483 mm x 215 mm) Net Weight 5.8 lb (2.6 kg) Operating Temperature 32ºF - 104ºF (0ºC - 40ºC) Cooling System Active, side venting GENERAL PC Configuration Software ControlSpace Designer software Network Control Ethernet (RJ-45), 100 Mb Communications Ports RS-232 (DB9M, DTE), Bose CC-16 (3.81 mm Phoenix Contact, 3-pin)
