KUTULUKA®

Compressor ya 527A imaphatikizapo dera la API lovomerezeka la THRUST lomwe limatha kusinthidwa kapena kutulutsidwa ngati pakufunika. Izi zimayika zosefera za THRUST pamaso pa chojambulira cha RMS chomwe chimachepetsa zomwe kompresa amachita ndi zomwe zili pafupipafupi. Zotsatira zake ndikuwonjezeka kowoneka bwino kwa nkhonya ndi ma frequency otsika, koma chizindikiro chophatikizika. Ndiko kusintha kwa "nkhonya pang'ono"! Dera lovomerezeka la THRUST lakhala likugwiritsidwa ntchito kwa zaka zambiri mu API 2500 Stereo Compressor yotchuka, 2500+, ATI Paragon ndi Paragon II consoles, komanso Pro6 Input Strip. Derali limayika fyuluta kutsogolo kwa chojambulira cha RMS chokhala ndi malo otsetsereka a 10dB pazaka khumi (-3dB/8va), komwe ndi kolowera mphamvu yamphamvu ya pinki. Mu ma acoustics, phokoso la pinki limagwiritsidwa ntchito kufananitsa mphamvu ndi ma frequency pa sipekitiramu yomvera, chifukwa phokoso limafunikira mphamvu yocheperako kuposa mphamvu yapafupipafupi kuti imveke bwino pamakutu anu. Pazida za Hi-fi, koloko ya "LOUDNESS" imagwiritsidwa ntchito
fanizirani nyimbo pamilingo yotsika kuti izimveka zolondola. Ngakhale pamapindikirawa, pamakhalabe chidziwitso chochepa kwambiri poyerekeza ndi chidziwitso chambiri panjira yamawu. Chizindikirocho chikalowetsedwa mu chowunikira cha RMS, chojambuliracho chimasinthira siginecha kukhala DC control vol.tage kutengera mafunde otsika kwambiri, zomwe zimapangitsa kuti voltage that favors the low frequencies of the signal, causing pumping and a loss of punch. Sometimes, this is not desirable. By engaging the THRUST ® switch, this inverse filter is placed in front of the RMS detector, evening out the energy by lowering the energy in the low frequencies and increasing the energy in the high frequencies, so each octave has the same energy instead of each octave having half the energy as the one lower. This creates a unique compression effect that still reduces the overall gain, but the sound is much more punchy and the signal actually sounds less compressed. With THRUST engaged (IN) gradual, linear filter, down 15dB at 20Hz and up 15dB at 20kHz is applied
ku chizindikiro chodyetsa chojambulira cha RMS, kufananiza mphamvu yopita mu chowunikira cha RMS. Izi zimachepetsa momwe ma frequency apamwamba amapanikizira. Kusiyana kwakukulu ndikuwonjezeka kowoneka bwino kwa nkhonya ndi ma frequency otsika, koma chizindikiro chophatikizika. Ndi ntchito "yowonjezera pang'ono".

Dera la THRUST litha kugwiritsidwa ntchito pogwiritsa ntchito switch ya THRUST.
