รายละเอียดสินค้า
The Bose® ControlSpace® ESP-4120 engineered sound processor is an open-architecture DSP with 4x12 fixed analog audio, built-in 8-channel ESPLink output and a rearpanel digital expansion slot offering IP-based network audio and control card options. This model meets today’s strict requirements for high-quality signal processing and control in a cost-effective package. The ESP-4120 is designed for a wide variety of applications ranging from small self-contained projects to larger networked applications.
The ESP-4120 accommodates a total of 56 audio channels through analog audio connections (4 input, 12 output), ESPLink (8 output), and when an optional Dante(tm) audio network card is used, an additional 32 channels (16 input, 16 output) are available for signal processing, routing and switching. Alternatively, a Network Control card is available for clean rear-panel control network connections. For standalone applications or convenient service access, a front panel Ethernet connector allows for local configuration and monitoring. Onboard connectivity includes Serial over Ethernet, RS-232, 5 control inputs and 5 control outputs.
Any of the elegant Bose wall-mounted user interfaces— including the programmable CC-64 and CC-16 controllers and three simplified zone volume interfaces—can be used to control all Bose networkable devices.
Open architecture configuration and control is enabled using Bose ControlSpace Designer™ software where an ever-expanding list of algorithms and improvements offers a high level of functionality for audio installations. Bose single-rack-space ESPs are designed for a wide variety of applications ranging from small self-contained projects to larger networked applications.
Applications Include:
- Auditoriums
- Houses of worship
- Resorts and hospitality venues
- Retail stores
- Schools and universities
- Multi-purpose spaces
- 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
- Expansion card slot supports the use of accessory networking cards, allowing digital audio to be sent and/or received from other compatible products
- Optional Dante™ media networking card allows single rackspace ESP products to closely integrate with Bose or other manufacturers’ products and systems
- Bose ControlSpace Designer software enables a large set of signal processing modules, such as automatic mic mixing, multiband graphic and parametric EQs, Bose loudspeaker libraries, signal generators, routers, mixers, AGCs, duckers, gates, compressors, source selectors and delays
- Front panel RJ-45 Ethernet connection enables localized configuration and monitoring, while enabling network passthrough when using a rear-panel network option card
- Built-in Bose ESPLink output sends up to 8 channels of uncompressed digital audio to ESPLink-equipped Bose PowerMatch amplifiers
- A variety of control options – ControlSpace ESP products are compatible with the programmable Bose CC-64 and CC-16 controllers and three simplified zone volume interfaces, as well as potentiometers and switches built by other manufacturers
- Integration with industry-standard control systems using a comprehensive serial protocol through onboard RS-232 and Ethernet ports
