Hi, i'm a newbie of this fantastic world and i have a great problem with my new home theatre system. I hope that someone helps me to solve it!
My system is:
Amp: Yamaha rxv640 rds
4 rti 28
1 csi 30 center
1 sub psw250
I put the sub in the corner on the opposite side of the room (5x6,5 mt.). To do this i used a high quality shielded rca cable(10 mt. long), from the sub out (mono) of the amp to the sub. Then, usin a y-RCAcable i connect it to the 2 line in of the SUB.
The problem is that powerin on the sub, some deep noise comes from it and there's no way to eliminate it.If i listen to music at mid-high level volume, there's no problem, but if i keep system volume low,i can hear this deep noise and it is fastidious. The sub's level volume is set at 50%. If i higher it, the noise increases too much.
If i lower it, the noise goes away, but the subs perform not enough bass to cover the range of the room.
I've tried another shielded sub-cable, but the problem persist.
What to do?
In attach: my system' position.
Thanks very much for any suggestion!
