Mafotokozedwe Akatundu
1. Chidule cha mankhwala
Zogwiritsidwa ntchito moyenerera pamayendedwe abi-directional (atha kusungidwa) ndi kufananiza kwamasigino amtundu wamitundu yambiri kapena maukonde ogawa omwe amafunikira kwambiri. Adopt PHILIPS, NEC yobwereketsa ma module owonjezera mphamvu. Audio pre-amplifier ndi phokoso lotsika la microwave chubu push-pull amplifier kuti atsimikizire kupindula kokwanira. Ili ndi zolowetsa 1 ndi zotulutsa 2, ndipo kulumikizana kulikonse kumakhala ndi chitetezo chopitilira apo. Nthambi yotulutsa kapena kugawa kungasinthidwe kutsatira. Double-equalizer imagwiritsidwa ntchito, kotero kusintha kufalikira kwamitundu yambiri ndikosavuta komanso kosavuta. Attenuator ndi equalizer ndi pulagi-in, kotero makasitomala amatha kusankha mawonekedwe okhazikika kapena osinthika. Mphamvu zosinthira zodalirika kwambiri (kapena mphamvu zofananira) komanso mawonekedwe osalowa madzi komanso odana ndi bingu amaonetsetsa kuti ntchito yokhazikika imakhala yokhazikika.
