Aphex 204 Aural Exciter and Big Bottom

Featuring the new Optical Big Bottom® for enhanced low-end response; two independent channels; internal power supply; XLR and 1/4' I/O; and improved overall sound quality and flexibility, the 204 markedly increases the presence & clarity of almost any audio signal. Unlike an EQ or other brightness enhancers, Aphex' process recreates missing harmonics without generating significant changes in the actual signal level. It extends high frequencins and enhances the stereo image, resulting in a greater perceived loudness without the introduction of noise due to increased gain. The new Big Bottom process provides deeper, more powerful bass performance without adding more power amps or speakers, and with little or no increase in peak output. The 204 is ideal for a everything from sound recording/mixing & broadcast/production to streaming audio, sound reinforcement, home theater, clubs, and more.THE AURAL EXCITER SAFELY ADDS EXCITEMENTThe Aural Exciter adds dynamically related harmonics to the signal at very low levels and these harmonics add little, if any, level to the signal. Because of the intelligence in the Aural Exciter side chain, the effect is useful over an extremely wide input dynamic range.DYNAMIC EQ ADDS MORE LEVEL FOR THE SAME AMOUNT OF ENHANCEMENTDynamic EQ boosts a part of the frequency spectrum when the input is above a threshold. If the input is already high, the additional equalization can result in overloading the amplifier, speakers or both.BIG BOTTOM VS. OTHER BASS ENHANCERSA speakers excursion increases with low frequency peaks. If those peaks are increased by a Dynamic EQ and/or a Subharmonic Synthesizer the speaker, at the very least, will fatigue more quickly. This will also increase the danger of the speaker jumping the gap or literally coming apart.Big Bottomadds little or no peak energy to the signal. Instead, it adds density (persistence of a low peak-to-average ratio).
