Marantz SR5015 Low Audio

So my old Onkyo Home Theater in a BOX 9400 THX i got years ago finally died. So i kept my old speakers from Onkyo and used those for the new marantz but the audio on almost everything is so low and the dialogue is SO LOW i used the Audyssey Mic and it still did not resolve anything. So i am a bit concerned and also angry that i need to put the volume to 10- just to even TRY to hear this thing. And the movies...I have to be doing something wrong or there some settings i need to fix SOMETHING it cant be this receiver that cost so much alone. So any help would be greatly appreciated as whenever i have any problem i used to come here and get it resolved i forgot my old login so i had to create a new account. Anyways thank you i will try to stay here and give info as much as i can i also do not know the specs for the speakers or whats proper for them like i said total noob here but i will understand what ya try to tell me if not ill ask to dumb it down lol. sorry for the wall of text.
