ISP Technologies introduces the revolutionary patent pending HUM EXTRACTOR™ + DECIMATOR G, two channel, ultimate noise reduction system. After years of musicians fighting the major noise problem of power line frequency hum, ISP Technologies eliminates this dreaded noise with the new patent pending HUM EXTRACTOR™. Power line frequency hum is most commonly caused by stray magnetic fields generated from transformers or power lines in close proximity to the instrument pickups. While Hum Bucking pickups have been in use for years to help reduce this problem, if the level of hum is severe, even Hum Bucking pickups are not enough and many players still prefer the sound quality and tone of single coil pickups. Line frequency hum has heavy harmonic content above the line frequency, which occurs at every interval of the line frequency. The Decimator technology has provided excellent ability to eliminate this for high gain applications by attenuating the output signal when the guitar notes decay but even the Decimator cannot remove the hum components that occur at clean or low gain settings since there is no masking of the noise at these settings. Once there is a guitar signal, the Decimator will come up to unity gain and at lower gain settings the hum will become audible. As all players know, the severity of the hum varies from venue to venue but it can destroy an otherwise great performance when severe. No other option exists that can offer the transparency to eliminate the hum while preserving the tone and sonic quality of the original signal. The HUM EXTRACTOR does the impossible and removes the hum without altering the tone of the instrument. 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.
