美国dbx:DriveRack PA 2进6出音频处理器技术参数

dbx DriveRack PA 2进6出音频处理器

一个基本音响系统的组成，是把话筒连接至调音台，调音台的输出经过一大堆周边器材然后送往功放，功放的输出连接至音箱。在一个音响系统里，周边器材配搭和边线是最为复杂的，而且器材种类繁多，包括用来令声音变得结实的压缩器，增强效果的激励器，修饰音质的均衡器，过滤或强化某些信号用的参数均衡器，消除啸叫声的反馈抑制器，保护喇叭单元的限幅器，调校喇叭时间差的延时器，补偿房间频响缺陷的均衡器……那么多的器材，把工程商都弄得头晕眼花，何况一般的用户。

经验稍逊的用户，见到多如天上繁星的显示灯，星罗棋布的控制键，千丝万缕的连接线，真的无从下手，望而生畏。 DriveRackTMPA的设计工程师了解用户的需要，设计了新一代的周边设备，把上述所有的功能集于一身。从今以后，从调音台至功放之间只需一款设备，一款包罗所有基本周边功能的控制器。不但如此，DriveRackTMPA的设计亦照顾到工程商的方便性，内置了大部分JBL音箱和CroWm功放的技术参数。工程商只需跟循着Setup Wizard（设置导航小精灵）的指引，顺序选择和输入设备的型号和工作状态，其余的繁琐微调工作便由DriveRackTMPA自动完成。

接上RTA-M标准测试话筒和开启了Auto-EQ自动均衡功能，DriveRackTMPA能自动调校房间的均衡，补偿部分因建声欠佳而引起的频响缺陷。快速跟踪的反馈抑制器加上精确的输出限幅保护，是用户和工程商的恩物，确保系统工作稳定。

DBX DriveRack PA

Drive your PA to a whole new level of performance with the DriveRack PA Complete Equalization & Loudspeaker Control System. The DriveRack PA from dbx Professional Products represents a complete integration of the key elements that help ensure optimal loudspeaker system management in PA-specific applications. Capitalizing on the legendary 480 DriveRack technology, the DriveRack PA is able to provide its user with top-tier, pro-level loudspeaker management specifications, yet still remain appealing to the budget-conscious audiophile who requires a tried and true utilitarian workhorse. With its all-inclusive, no-compromise design, the DriveRack PA has been systematically developed and designed to grow with your system needs for years to come.

The DriveRack PA continues the legacy of DriveRack series, which has been created by the company that has been redefining the standard of signal processing for more than 30 years. The DriveRack PA was designed with the purpose and vision of providing state-of-the-art signal processing, while utilizing a simple and intuitive user interface. This goal has been achieved by offering 2 independent channels of processing power with a linkable 28-Band Graphic equalizer, industry-standard dbx stereo compressor module, feedback eliminator and the 120A Subharmonic Synthesizer on the input, with a six channel output system that includes parametric Eqs, and Peak Plus limiters (which are used to provide protection against speaker blowouts) and alignment delay. These features combined with the Wizard setup system, represent a methodical design that is guaranteed to deliver optimal, all-inclusive processing in a completely scalable system.
