Ingcaciso yeMveliso
1. Isishwankathelo seMveliso
Isetyenziswa ngokufanelekileyo kwi-bi-directional transmission (inokugcinelwa) kunye ne-signal equalization ye-multi-class trunk transmission okanye inethiwekhi yokusasaza efunekayo kakhulu. I-Adopt PHILIPS, iimodyuli zamandla ezingeniswe ngaphakathi ze-NEC. I-audio pre-amplifier yi-microphone tube push-pull amplifier enengxolo ephantsi ukuqinisekisa ukufumana okwaneleyo. Ine-input enye kunye ne-outputs ezi-2, kwaye uqhagamshelo ngalunye lunokhuseleko olugqithisileyo. Isebe lemveliso okanye i-distributiveness inokutshintshwa emva kwayo. Kusetyenziswa i-double-equalizer, ngoko ke ukulungisa i-multi-class transmission flatness kulula kwaye kulula. I-Attenuator kunye ne-equalizer ziyi-plug-in, ngoko ke abathengi banokukhetha isitayile esizinzileyo okanye esihlengahlengiswayo. Amandla okutshintsha athembekileyo kakhulu (okanye amandla angqalileyo) kunye noyilo oluqinileyo lwamanzi nolwe-anti-thunder luqinisekisa umsebenzi ozinzileyo.
