Since its introduction in 1975, close to a million Aphex Aural Exciters have found their way into recording studios and broadcast facilities, nightclubs and concert halls, arenas and airports, musicians' and DJs' rigs and houses of worship. The Aural Exciter's patented technology has been often imitated but never duplicated.

Each of the Aural Exciter's two independent channels feature Tune, Harmonics and Mix controls, enabling you to focus on select frequencies just like an EQ. But unlike an EQ, the Aural Exciter's harmonic processing doesn't boost the signal's output level, maintaining a clear and balanced sound.

Traditional EQ increases the output level of the targeted frequencies. Adding EQ to boost selected frequencies typically results in a perceived loss of other frequencies, which are then also boosted to compensate. The Aural Exciter's patented technology harmonically brings out the desired frequencies without adding gain. The result is audio that's more balanced, more articulate and, simply put, better sounding.

Over three decades of research, development and refinement have kept the Aural Exciter at the cutting edge. The new Aural Exciter and Optical Big Bottom features the same no-compromise audio quality Aphex is known for, with the highest quality componentry and rugged, durable construction to withstand the rigors of travel and constant use.

Aural Exciter

For more than 35 years, the Aural Exciter's patented technology has been the audio professional's secret weapon, a powerful way to improve and enhance sonic quality more naturally than with equalization.

For individual sounds or entire mixes, the Aural Exciter brings out detail, clarity and imaging that elevates your sound without adding level. For vocals and spoken dialog, it can dramatically increase intelligibility. For individual instruments, it adds punch and presence. And on mixes, it adds power, presence and sparkle. The Aural Exciter is the ideal solution for breathing life into MP3s and other compressed audio files.

Optical Big Bottom

The Optical Big Bottom adds a deep, powerful low-frequency punch, without the unwanted level boost that comes from adding traditional EQ. Deeper, more resonant bass response with tighter articulation helps to extend low frequency power and spectrum without the build-up or driver-damaging tendencies of bass EQ.
