... General Descriptions The GL6552 is a Compander IC, which contains two variable gain circuits configured for compressing and expanding the dynamic range, and improving of S/N ratio of audio signal. It consists of compressor, expander, Mic Amp, limiter, ALC(Automatic Control)and mute logic. The compressor circuit has the 2/1 ratio of input/output ratio by logarithm, and the expander circuit by logarithm ...
