Overview
Setifikeiti sena sa 1500W FM se amohela mohopolo oa moralo o bonolo mme se kopanya sehokelo le amplifier ea matla, filthara e hlahisoang, phepelo ea motlakase, joalo-joalo molemong oa 2U e phahameng ea 19-inch. Moralo ona o tsoetseng pele o fokotsa palo ea likhoele tsa khokahano mme o ntlafatsa ts'ebetso e akaretsang ea transmitter, e etsa hore e ts'epahale le ho sebetsa habonolo.
Sesebelisoa sena sa 1500W FM se na le chassis e tloaelehileng ea aluminium ea 2U 19-inch. Pontšo ea LCD ea 3.5-inch, theknoloji ea PLL-locked loop frequency modulation ea dijithale, boleng ba molumo oa CD, amplifier ea ho qetela e sebelisa li-transistors tsa LDMOS tse sa sebetseng hantle. Transmitter ena ea 1500W FM e ka kenya lets'oao la molumo oa analog kapa lets'oao la modulation ea analog, le lets'oao la dijithale la AES / EUB.
