Hi Houstonreef,
re your Syrah, the sitch top front is for the tape loop,
should be in the forward position unless the tape loop is in use.
The two toggles mid top alter the gain of the line stage(one for each channel),
on mines at least they switch backwards for high gain & foward for the lower gain.
The 5 position switch to the rear is in it's highest setting when turned fully anti clockwise and reduces the gain when switched clockwise.
I tend to set the gain as high as I can without 'tube rush' being intrusive but that will depend on your system.
Hope this helps
