TOPP PRO TMA 250.4 četvorokanalno pojačalo

TOPP PRO TMA 250 je 4-kanalno pojačalo koje na stereo režimu na 8 ohma izbacuje 145w po kanalu, a na režimu od 4ohma snaga koja izlazi je 220w po kanalu. Ovaj pojačivač je interesantan po svojoj snazi i mogućnosti povezivanja više zvučnika u jednom objektu. Lokali sa više prostorija, kafići sa više zvučnika, bašte restorana, monitoring na bini i mnogo toga još.

Garancija kvaliteta 2 godine.
