Coron Noise Gate
a 1981 Coron brochure
The Noise Gate was developed to solve the problems of background noise & hum, and provide a convenient high impedance/low impedance interface for direct line taps. The threshold control allows you to adjust the level at which the Noise Gate cuts off, removing unwanted noise between notes and at the end of performances. The Noise Gate can be switched ON/OFF, to allow for special effects.
