分立设计的双通道立体声压缩器
特性:
1,API 2520 运算 放大器
2,可变门槛 -20和+10
3,可选比率,开启及释放时间
4,分类的RMS侦测器之前的插入式高通滤波
5,可变的左右通道连接
6,反馈式压缩
7,易于锐化压缩的软硬斜率
8,自动手动增益控制
9,1/4"平衡侧链输入
10,输出降低到+30dBm
API 2500 通用立体声压缩器可调整声音质量:转换立体声混合的声音音调。可装载于19"机架。由于其双通道的设计,API 2500为立体声压缩器,但也可以通过一个单通道压缩设置而改变为两个独立通道。2500引以为傲的参数设定范围使其具有难以置信的音乐性。
API改进了可选"经典"或"新型"的压缩设定。经典设定使用了525,1176,Fairchild中反馈式压缩。新型设定使用了于目前流行的其他压缩器一样的前馈压缩。
输出接口有API自动结构增益按钮,允许用户在自动保持恒定输出的情况下变化门槛或比率。全分立,全平衡的设计加上前面板上显示输入,输出及增益衰减的双VU表保证了信号的清晰度。

The API 2500 Stereo Bus Compressor allows adjustment of sonic qualities to .the punch.tone of the stereo mix. One of the 2500.s notable qualities is its use of API.s patented THRUST circuit for a chest-hitting, punchy bottom end. The 19-inch, rack-mountable unit boasts a dual-channel design that can be configured for stereo compression.for use as two separate units via a single compression setting.
Another unique feature of the 2500 is its .able "old"."new" compression. The old style uses the "feed back" type of compression found in the API 525, while the new style uses a "feed forward" type in which the compressor side chain is fed directly from the unit input. Additionally, the output stage exhibits an auto-makeup gain button that permits the user to vary the threshold.ratio while automatically maintaining a constant output level. Further, the 2500 ensures fidelity with its all-discrete, fully balanced design with two front panel VU meters showing input, output.gain reduction levels.
