Check out this from the APHEX website:
"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"
Huh? Did we read that correctly? CLOSE TO A MILLION!
This latest incarnation from Aphex, simply called EXCITER, also includes Optical Big Bottom circuitry on each of the two channels.
If you want a step-by-step view of the controls, you can check the 7min video on the tab below – otherwise, here is the brief version:
Exciter is a two-channel rackmount audio processer. Each of the two channels can be independently switched to ‘process on/off’ on the front panel.
Each channel has controls for:
Big Bottom – Drive, Frequency (50-200Hz) , Amount
Aural Exciter – Frequency (600 – 5,000Hz), Harmonics, Amount
The Optical Big Bottom adds deep, powerful low-frequency punch, without the unwanted level boost that comes from adding traditional EQ.
The Aural Exciter's harmonic processing doesn't boost the signal's output level, so it maintains a clear and balanced sound.
