Jeg har en QSC 70v 1202v effektblok. Er der nogen som ved om det er muligt at tilslutte alm. 8 ohms højtallere til sådan en uden at anvende trafo?? QSC teknisk service i USA skriver at det kan man godt, men jeg tvivler stadig, en alm højtaller er jo ikke isoleret/ bygget til denne spænding. Men er der indbygget noget elektronik som kan detektere hvad der er sat på?? Nogen som har arbejdet med dette??

Tjaaah...det´ser ud til det ikke er noget problem...

mvh

Hvis man regner lidt på en normal amp (ohms lov)på 700w til en 8 ohms højtaller så lander man også en max spænding på ca 70-75 volt, kan en alm højtaler tåle denne spænding?? Men hvis man læser i spec. ser det ud som om der kan tilsluttes en alm speaker på den. Men men men kan det tænkes at det er opgivet MED en 70v trafo foran.

Jamen der står jo netop 700W/8ohm...så må man jo bare have nogen højtalere som kan det.

mvh
