JH says about mixers...."Yes, and they run line level 
internally, and also tend to have a +/-15V supply."

At Soundcraft they use +/-17V5. Its generated by LM317s in the psu. It is
about the most you can put into an ordinary TL07x without it complaining.
That extra 2V5 seems to be worth the hassle.

They also use the EBOS, electronically balanced output stage, a 5532 with
SIL pack resistors for matching. It should drive 600R. It handles TRS and
TP plugs with ease.
