904 Noise Gate

The 904 is an expander gate using the dbx® OverEasy® action for a smooth onset of gating. Attenuation limit, attack and release rates and threshold are all adjustable. This popular gate also features Programmed Latch Mode which mutes a channel until an above threshold signal is present. It then latches open until reset. The 904 is a very fast voltage controlled below threshold downward expander. It senses the level of an input or keying signal and determines whether the level is below threshold....
