just be careful of the higher current draw that the 5532 has on the 
power supply - too many of these may stress the power supply past 
what it was designed for...

what do people think of the 4560 and 4580 (apparently popular with 
mackie and behringer respectively)? these seem to be very cheap at 
mouser...
