Pre volume control - hardly moves but volume rises a lot

I have older Pioneer equipment.
I hooked my sc - 700 Pre to my sa - 700 Integrated amp.
The amp has separate pre out and main in.
It works ok but the Pre volume control just doesn't seem right.
I only move the control a tiny amount for the volume to rise a huge amount.
The volume has 10 loudness marks and I can not even get to the first mark and the volume is very loud.
Any thoughts?

Is the volume ok when you are using the SA-700 without the SC-700?

Is the switch in the back set to an amplifier only position?

+1 gs5556 good pickup.

Yes the switch should be up to separate, in case you missed it. If not you have too much gain get the Schiit.

Yes it is on separate and the volume is ok without the pre.
The volume on the amp does nothing when the pre is hooked up,
only the volume knob on the pre changes the volume. is that normal?

Yes, that means the integrated pre section has been cut out.

You have too much system gain. With the sources output, other preamp gain in conjunction with the gain of the poweramp section, and the efficiency of the speakers.

Look at the Schiit Sys for $49.
