Dhau li ntawm qhov yooj yim microphone tuaj tos, sib tov, thiab desktop amplification technologies, lub ntsiab technologies ntawm lub rooj sib tham system muaj xws li suab kis tau tus mob technology, digital control technology, computer tswj technology, high-fidelity reliability technology, thiab coj mus muag tswj thiab tswj software.
Thaum ntxov lub rooj sib tham systems siv analog suab kis tau tus mob, ua rau kuj yooj yim tswj technology. Thaum lawv tuaj yeem ua tau raws li feem ntau ntawm cov kev xav tau ntawm lub rooj sib tham, lawv txoj kev sib txuas lus analog feem ntau ua rau cov teeb meem hauv qab no:
1) Tshaj qhov deb (ntau tshaj 50m), lub teeb liab - mus rau - suab nrov piv, kev sib cais channel, thiab zaus teb cov yam ntxwv tsis zoo, ua rau lub suab tsis zoo.
2) Lub rooj sib tham loj tau ntsib kev cuam tshuam loj heev vim muaj teeb meem hauv av (xws li, los ntawm cov khoom siv teeb pom kev zoo, cov khoom siv hluav taws xob, khoom siv sib txuas lus, thiab tshaj tawm hauv TV).
3) Thaum siv ntau-channel kev txhais lus ib txhij, txhua hom lus yuav tsum tau muaj kab sib kis. Kev sib txuas lus ntau yam tau ua rau cov kab sib txuas tsis yooj yim, ntau qhov kev sib txuas tsis ua haujlwm, thiab kev cuam tshuam kev ntseeg siab.
