产品介绍

■ YS处理(雅马哈扬声器处理)具有与本公司俱乐部系列扬声器完全匹配的性能，从而使整个系统获得最佳性能。
■ 各个通道中独立、可扫描高／低通滤波器可优化超低音扬声器或整个系统的输出，从而在任何系统中都可获得最高音频品质和性能。
■ 重量轻使得运输和组装都非常容易。
■ 由于每个通道都采用Neutrik speakon输出插口和1／4英寸输出插口，再加上5路接线柱，可提供杰出的连接灵活性。
■ 专门设计的底盘，可提供额外的耐用性和强度。
■ 所提供的综合保护措施包括电源开／关静音、Dc检测、热保护、电流l限制和衰减器保护罩。
■ Yamaha独特的EEEngine(引擎)技术使得系统能够异常高效地运行，通过大幅降低Ac电能消耗和降低发热，最终降低运行成本。
