Product Description
The IGS ONE LA is an optical compressor, inspired by the legendary solution well known from the &＃39;60s. This is a very easy to use and great sounding tool.
Design
The IGS ONE LA is an input and output transformer balanced, full tube device. The input of the system includes a Sowter 4383 transformer, the output an Edcor 15k/600. Two 6N1P-EW dual-triodes are installed on the audio circuit, while the compression circuit is equipped with the 6N2P-EW triode and the 6AQ5 pentode, which control the work of the T4Bx photocell.
Controls
The One LA 19" has simple controls: a Peak-Reduction knob controls the gain of the side-chain circuit, and therefore, the gain reduction threshold; Gain Control for the make-up gain; and a Limit/Compress switch to alter the compression ratio. The VU meter may also be switched to show gain reduction or output level.
T4Bx Optocell
The original solution used the TELETRONIX electroluminescent panel, that was illuminating the photo resistor. The idea of opto-compression originated in the past is still being cultivated today. IGS Audio has developed its own photocell equivalent to T4B called T4BX. The use of carefully selected components in the production of the T4BX photocell, and their individual measurement and matching, result in completely repetitive sound qualities of each device.
Stereo pair
Matched pairs are also available. The link socket is located on the rear panel. The RCA-RCA cable is all you need to link two units. Perfect stereo matching is achieved by hand selected tubes and Elma switches.

产品说明
igs one la是一种光学压缩机，灵感来自于众所周知的60年代的传说中的解决方案。这是一个非常容易使用和伟大的发声工具。
设计
其中的igs one la是一个输入和输出的变压器平衡，全管装置。系统的输入包括一台4383变压器，输出为15k/600。
控件
一la 19"有简单的控制：峰值减速器控制侧链电路的增益，因此，增益减缩阈值；增益增益的增益控制；以及改变压缩比的限制/压缩开关。vu仪表也可以切换，显示增益降低或输出水平。
t4bx光电池
原来的溶液使用的是电螺线电致发光面板，它照亮了照片的电阻器。光学压缩的概念起源于过去，到今天还在被培养。igs音频开发了自己的光电池，相当于t4b，称为t4bx。在生产t4bx光电池时使用精心挑选的部件，以及它们各自的测量和匹配，导致每个设备的音质完全重复。
立体声对
还提供匹配的对。你只需要用RCA-RCA电缆连接两个单元。***的立体匹配是通过手工选择的管道和电子开关实现的。
