Hi Christian,
 
You do realise that the the +-15V is the supply to the device, ie you will need to supply it with +15V and -15V of DC power with the GND being the common for both the supply and output signal.
 
You can easily build a +-15V supply with very basic components, but you would be quicker to pickup a surplus switch mode power supply with the required outputs. Check out www.greenweld.co.uk for some really low cost units.
 
Regards
Dave...
