studiomaster Powerhouse 300 8-2

[marmaladesoup]

Hi there i recently aquired a Studiomaster 300 8.2 powerhouse mixer. All seemed to be well when i got it home, Powers fine all the lights etc even tried the headphone socket and can hear everything fine. But alas when i try to plug my speakers into the outputs in the back i am greeted with silence ???
Does anybody have any ideas how this could be resolved and even what may have happened. Many thanks Ross
