So you are saying that when you fire up the amp the music is at max volume?
If so the only things I can think of are:
1. The previous owner converted the integrated to a power amplifier by disabling the volume. If so you'll need a volume control of some sort, or reconnect the volume. You can open the cover and look at the volume knob.
2. There are 2 sets of outputs on the back, variable through the volume control and fixed maybe for a tape loop or something.
