GML 8900 Dynamic Range Controller (Used)

The GML 8900 is a two-channel unit with an all discrete-transistor audio path that features an extraordinary range of control, allowing simulation of various fundamental automatic gain-control characteristics. The GML 8900 is the result of 22 years of research, prototyping and limited manufacturing. It features two RMS and one peak detector per channel, multiple variable crest factor controls and selectable soft/hard knee adjustments. The unit combines highly accurate log converters, true RMS detectors (which provide control of signal energy not just level), and other modern analog processing techniques in a stable "feed-forward" topology.
