Benchmarkova ekskluzivna plo\u0161\u010da oja\u010devalnika za slu\u0161alke THX-888 ima patentirano tehnologijo THX-AAA. Ta tehnologija vklju\u010duje sistem za odpravljanje napak naprej, ki zmanj\u0161a popa\u010denje za 30 do 40 dB. Popa\u010denje in \u0161um sta pod sli\u0161nim pragom 0 dB SPL, tudi pri delovanju z najzahtevnej\u0161imi slu\u0161alkami.

Ta sistem je zasnovan tako, da zagotavlja najni\u017ejo mo\u017eno raven \u0161uma in popa\u010denja pri kateri koli nastavitvi glasnosti.
