Before I blow anything up can I please ask someone to help out and
double check something?

I want to buy this power supply:

Dial in 0.5 A and +12 V for the variable output and it already has a
fixed output of the same ratings. I want to generate +12 V and -12 V,
is it just a matter of connecting the +12 V of the second supply to
the 0V of the first supply so that pushed the second one's 0V is
pushed to -12? Also is +- 12 V enough to run most audio circuits even
if they are +-15 V on the schematic?
