The position of the HUM EXTRACTOR can be selected to operate in either Channel 1 or Channel 2 based on the users preference and rig configuration. The HUM EXTRACTOR + DECIMATOR G is a high performance two channel DSP processor with three noise reduction operations in one unit. The HUM EXTRACTOR, typically in channel 1, is inserted between the guitar output and the input of the guitar rig. Channel 2 is then inserted after the gain or preamplifier in the rig and provides Decimator Noise reduction with the newest patent pending Decimator X technology for the ultimate adaptive release. The Decimator level detection is derived from the direct guitar input signal after removal of the hum components providing perfect tracking of the Decimator functions without the hum components. This allows greater precision for the Decimator to remove gain noise and gain hiss.
