The Behringer NR300 Noise Reducer is a practical aid for all guitarists seeking to remove unwanted noise from their signal path without distorting the sound. It reduces unwanted noise in reduction mode. The threshold control determines the threshold of the noise gate, while the decay control determines how long the gate is active. In mute mode, however, the Behringer NR300 Noise Reducer mutes the entire signal after the footswitch is pressed. A further practical detail is the FX loop of the Behringer NR300 Noise Reducer, which can be used to remove background noise from particularly sensitive effects pedals.
