This is a discontinued item. I'm not sure Aphex even exists anymore, I couldn't even find their site. Here is an archived description of the unit from Sweetwater:
For years, professional audio engineers and producers have relied on Aphex's Aural Exciter to brighten up sound dulled by risky equipment or a difficult A/D transfer. Now, with the Model 204, Aphex has brought back the Aural Exciter in an enhanced, 2-channel version - and thrown in the Optical Big Bottom for extra measure!
Aphex Aural Exciter 204 with Big Bottom at a Glance:
Dramatically increases presence and clarity of highs and lows
Extends high frequencies with no added noise
Gives low notes greater resonance
Does all this with no increase in peak volume!
Dramatically increases presence and clarity of highs and lows
The Model 204 dramatically enhances the presence and clarity of your audio signals. On the high end, the Aural Exciter restores natural brightness and improves sonic detail. The Big Bottom performs a similar function on the low end, providing deeper, more resonant bass with little or no increase in peak output.
Extends high frequencies with no added noise
The Aural Exciter is more than just another "audio enhancer"; it actually extends your high frequencies for a greater perceived loudness without an introduction of noise into the audio path due to increased gain. Vocals and instruments leap out without raising individual volumes in the mix.
Gives low notes greater resonance
The same can be said for the Optical Big Bottom capabilities of the Model 204, except on the opposite end of the sonic spectrum. Big Bottom tightens and boosts the bass, allowing individual notes to be more articulated and recognizable, providing a deeper, more resonant bass without overloading the sound system.
Does all this with no increase in peak volume!
With the Model 204 in your setup, your audio will be fuller, bigger, and generally sound louder, but with little or no increase in peak volume. This is a versatile tool for a huge range of applications, from recording to broadcast to performance.
