美国dbx:DriveRack260 2进6出音频处理器技术参数

dbx DriveRack 260 2进6出音频处理器

两组输入，六组输出，组合灵活。两组输入的前端均包括28段的图示均衡或9段的参数均衡。共有2.7秒的数字延时资源，可以加插在输入和输出通道。六组输出均设有4段的参数均衡和限幅器。AGC自动增益控制，可以加插在输入或输出通道。确保音响系统的输出音量保持平稳，不受演讲者忽大忽小的语音而影响观众区的音量。内置粉红噪声发生器和实时频谱分析仪。在A/D过程中，信号过载而引致的失真非常严重，dbx专利设计的Type IVTM A/D转换电路克服了这技术难关，从而扩展了动态范围。然后，还可以插入以下功能的其中两种，包括：陷波滤波器，压缩器，自动增益控制，分谐波合成器或dbx专利设计的AFS反馈抑制器。数字式分频器，滤波器特性可以选择Bessel、Butterworth和Linkwity-Riley。dbx专利设计的AFS反馈抑制器共有2×12个快速跟踪陷波滤波器，只消除啸叫声，保留有用的节目声。陷波滤波器可选择部分是固定的，部分是浮动的。接上 RTA-M 标准测试话筒(于背板)和开启了Auto EQ功能，DriveRackTM 260便能自动调校房间均衡，补偿部分因建声欠佳而引起的频响缺陷。

DBX DriveRack 260

There is a reason that Tour Sound Professionals and discriminating Audio Contractors choose dbx DriveRack products for their high-end tours and installs. The DriveRack products provide the tools that ensure that the system sounds its very best. With the introduction of the new 260, the heritage of unrivaled system/loudspeaker control continues.

The 260 capitalizes on the road tested and contractor approved nature of the other products in the DriveRack line. The 260 provides full bandpass and crossover configurations as well as independent output processing and a full time RTA for live sound applications. Contractors will appreciate its control inputs for wall-panel logic control and the patent-pending Advanced Feedback Suppression (AFS).

The DriveRack 260 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 260 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 two 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, PeakStopPlus? limiters (to provide protection against speaker blowouts) and alignment delay. These features combined with the Wizard setup system and complete DriveWare GUI control represent a methodical design that is guaranteed to deliver optimal, all-inclusive processing in a completely scalable system.
