KUTUNGAMIRIRA®

Iyo 527A compressor inosanganisira API's patented THRUST dunhu rinogona kuchinjirwa mukati kana kubuda sezvinodiwa. Izvi zvinoisa iyo THRUST sefa pamberi peRMS detector iyo inoderedza kuita kwecompressor kune yakaderera frequency yemukati. Mhedzisiro ndeyekuonekwa kwekuwedzera kwe punch uye yakaderera frequencies, asi yakaenzana compressed chiratidzo. Ndiko chinja che "zvishoma zvishoma"! Iyo patented THRUST yedunhu yakashandiswa kwemakore mazhinji mune yakakurumbira API 2500 Stereo Compressor, iyo itsva 2500+, ATI Paragon uye Paragon II inonyaradza, pamwe nePro6 Input Strip. Dunhu iri rinoisa sefa pamberi peiyo RMS detector ine mutsetse we10dB pamakore gumi (-3dB/8va), inova ndiyo inverse yepink noise energy curve. Mune acoustics, pink noise curve inoshandiswa kuenzanisa simba rinopesana nefrequency pamusoro peaudio spectrum, sezvo ruzha ruchida simba rakawanda rakaderera pane simba remhepo kuti rinzwike munzeve yako. Mumidziyo yeHi-fi, “LOUDNESS” contour inoshandiswa kuita
enzanisa mimhanzi pamazinga akaderera kuti iite seyakanaka. Kunyangwe neiyi curve, kuchine huwandu hwakakura hweiyo yakaderera frequency ruzivo kana ichienzaniswa nepamusoro frequency ruzivo munzira yekuteerera chiratidzo. Kana iyo chiratidzo ichipihwa muRMS detector, iyo detector inogadzirisa iyo chiratidzo muDC control vol.tage yakavakirwa pane iwo akanyanya kudzika mafrequency, zvichikonzera vhoriyamu yekudzoratage 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
kune chiratidzo chekudyisa RMS detector, kuenzana simba rinopinda muRMS detector. Izvi zvinodzikisira nzira iyo mafrequency epamusoro anodzvanywa. Musiyano wakazara ndewekuwedzera kunoonekwa kwe punch uye yakaderera frequency, asi yakafanana yakamanikidzwa chiratidzo. Iri ndiro basa re "zvishoma zvishoma".

Iyo THRUST yedunhu inogona kubatanidzwa uchishandisa THRUST switch.
