GML 8900 Dynamic Range Controller
"The Limiter"
This two-channel unit with all discrete-transistor
audio path features an extraordinary range of control allowing simulation of various
fundamental automatic gain-control characteristics. The 8900 is the result of 22 years of
research, prototyping, and limited manufacturing. 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.
• distortion reduction in the signal level
determination processor
• optimum smoothness of the "soft knee"
transition generator
• maximum transparency and low-level resolution of
the discrete VCA circuitry
Product Highlights:
2 channels, each with
Separate Peak and Dual RMS Detectors
Discrete VCA; Discrete Audio Chain
Front Panel Sidechain; Stereo and multiple unit control link
40 Segment Tricolor meter; Meter range -20 to +20, true gain through unit
4 segment instantaneous ratio meter (approximate indication of soft knee actuation)
