I have this machine in my home and i was wondering if i could use it as an receiver to connect more speakers make an home theatre sound system as i seems to be an 5.1 receiver.or is it an amplifier that i can connect speakers to it to make it louder?it seems to be connecting with the Speaker's copper wire to a hole labeled speakers?it is part of a hi-fi system that comes with an cd player,fm tuner and a cassette tape.it was bought during the 90s i think.

thx and if you need any more info i will try to find it but i have already lost the manual.
It was an stereo integrated amplifier i dont know what that means so can someone clarify?
and there are two holes for each left and right that was labeled + and -
