FAQ

Kodi mutha kupanga chowulutsira makanema opanda zingwe a UHF ndi amplifier 10-watt?

Tsopano tilibe chosinthira mavidiyo a analogi okhala ndi 10-watt PA. Sikuti kungowonjezera 10-watt PA ku makina athu apakanema omwe alipo. Iyenera kukonzedwanso ndi kupangidwanso.

Katswiriyu akuwonetsa kuti muyese kaye mavidiyo athu amtundu wa analogi poyamba. Mukatha kugwiritsa ntchito, tiuzeni zomwe ziyenera kukonzedwa ndipo titha kuziwonjezera pazatsopano zatsopano ndi 10-watt PA. Kotero mungakonde kuyesa chitsanzo chomwe chilipo (pa PA) choyamba?
