The 323A Compellor/Aural Exciter from Aphex is a single channel dynamics processor and program enhancer that permits absolute control over program dynamics.
The "Compellor" section is a self adjusting dynamic audio processor with "intelligent" control electronics that monitor and control long term dynamics, while simultaneously providing excellent leveling, compression and peak limiting action. Set-up and operation are simple and virtually fool-proof.
The "Aural Exciter" section enhances and restores program material, resulting in increased audio presence, intelligibility and articulation.
