Echo ATS
声学测试系统

Echo ATS™ 测试系统是一个紧凑型音频测试平台，用于大批量生产线出货测试非常适合。ATS整合多个单独设备的功能于一体集成单元，让生产线测试站更加可靠，成本更加经济。

ATS具有灵活的软件可配置的模拟和数字IO选项，可用于许多类型音频产品测试或在选择被测产品之间便利切换。

The ATS兼容USB 2.0音频类别，像声卡一样工作。标准的音频驱动提供与工业领先的音频测试软件无缝支持。

The design of the ATS draws on our decades of experience creating high-quality consumer and professional audio interfaces as well as its predecessor, the AIO modular test interface.
