BOSE ESP-88 音频处理器
Bose ControlSpace ESP-88 音频处理器是一款功能强大的数字信号处理器，在一个可扩展的机箱内提供控制和音频处理功能。
ControlSpace 音频处理器具有两种型号：
ESP-00: 出厂时没有预配音频扩展卡，可根据项目的需求自行配置扩展卡。
ESP-88: 出厂时预先配有8×8的音频扩展卡，具有标准动态范围的8路输入和8路输出。
ControlSpace 音频处理器集成了一套完善的音频处理算法，具有灵活的信号通道和可适应的扩展卡架构，是音响工程应用场合的出色解决方案。对于大型的应用场合，可以选配各种音频通道扩展卡，选配的 DSP 扩展卡，能将处理器的性能和延时存储器提高到四倍。多台处理器也可组合在一起使用。ControlSpace? 处理器可选择多种用户控制界面，包括
ControlSpace CC-4 区域控制面板、CC-16 区域控制器以及 CC-64 控制中心。
Bose ControlSpace DesignerTM 设计软件(随机器附送)可以对 ControlSpace? 处理器和各种用户控制界面进行设置。Smart Simulation 智能仿真编程能立刻让您测试及验证所有的控制功能。该软件运行于PC电脑，通过以太网与系统进行通讯。

The power to connect. The simplicity to control.
ControlSpace? ESP-88 systems offer a new approach to meet the needs of sound contractors and system users. These systems deliver powerful, flexible, sophisticated signal processing with elegant user controls that promote user confidence in daily system operation.
Engineered Sound Processor
The Bose ControlSpace ESP-88 engineered sound processor is a flexible, expandable and high quality audio signal processor for engineered sound applications such as houses of worship, theaters, auditoriums and sports venues. The base model (ESP-88) includes eight inputs (microphone or line-level selectable) and eight line-level outputs. Four available audio slots allow the addition of up to 16 more analog audio channels—inputs, outputs or a combination—or up to 32 more digital audio channels (AES3) as inputs, outputs or a combination. For large applications, multiple ESP-88s can be used per system. Multiple choices of user controllers are available to provide end users with simple, easy-to-use control of their ControlSpace system.
Recent Enhancements
New software additions include:
Password protection: Prevents unauthorized access to the system
IP addressability: Enables the ControlSpace system to use and share IT networks with other products
Expanded serial protocol: Allows the ESP-88 to be more easily integrated in installations requiring audio, video, lighting and other controls using Crestron, AMX or other third party devices
CC-16 enhancements include:
Ability to preview the Selector Input or Parameter Set name prior to its selection
Displays "Mute" when muted from the ControlSpace Designer? application or a Parameter Set
Minimum volume default is now -60 dB, and displays mute when minimum volume is reached
When a Parameter Set recall changes the mapping of the CC-16 volume, the current gain of the device is now used
