hi all, need help
my diy front ht speakers consists of 12" bass jbl le120h1-s, 6,5" midrange jbl gs726 and high freq. 1" compression driver jbl 2426.
power comes from 2 carver av 705x consumer poweramps(5x125w each). only rca inputs.
crossover is a dbx driverack pa+.
my tweeters has a small hiss when only connected to the poweramp and the poweramp is not connected to the dbx. this doesnt bother me.
when i connect the poweramp to the dbx the hiss becomes much louder, its like leasening to a seabreeze
i only sitt 6 feet away, because of roomsize!
it doesnt influence the hiss if the dbx is connected to my pre-amp or not.
do you pa+ users have the same problem? or do you have any ideers that maybe can help me?
ps sorry for the bad enghlish.
