Description:
The ALTER is a single-channel unit with stepped input and output controls. The Ratio switch has six positions, including two additional to the original 1176 1:1 and 2:1 settings. Slam Mode can be turned on with a separate switch, working regardless of the Ratio settings. Attack and release times can be set to Fast / Mid / Slow with 3-pole switches. The compressor is equipped with a relay bypass, achieved on the front panel. The input is balanced with a modern, low-noise op amp and the output with a Carnhill transformer. The circuit has two amp stages, between which is the output control. The stage amps are based on the discreet API2520 circuit. The level of gain reduction is shown by a 30 point led bar.
The ALTER 500 is a FET compressor built is the 500 standard. The FET-type solution was used for the first its application in the legendary UREI 1176 compressor from the 70s.

描述：
该变换器为单通道单元，具有阶梯式输入和输出控制。比例开关有六个位置，包括两个额外的原1176 1:1和2:1设置。可以用一个单独的开关来打开关闭模式，无论比例设置如何都可以工作。攻击和释放时间可以设置为快/中/慢，有3极开关。压缩机在前面板上安装了继电器旁路。输入与一个现代的，低噪音的操作放大器和输出与煤山变压器的平衡。电路有两个安培阶段，两者之间是输出控制。舞台安培是基于谨慎的像素2520电路。增益减少的水平用30点的led条表示。
