LFE signal booster

[Muckman2000]

Hey all

I got a Crown 1500W for my subwoofer and was wondering if there’s a way to rase the line level for the LFE because to get anything decent out of it I have to run the amp volume at almost 100% causing all sorts of crap through the sub

The noise goes away if I crank it down to about 50% but I barely get anything coming out of the sub.

Would boosting the LFE line with a preamp or something help me here ?

Any suggestions?

What are you running the amp from?

Considering I mention it’s a life line I can assume you already know it’s from a AV receiver. But as for type it’s a onkyo tx-rz820
Input Voltage on the crown amp at .775 V
Lfe output lvl at full 12db
Speaker lvls at 0db
Normal main volume set at -30db
Would this be the reason ?
Should I turn down my speaker lvls and set the main volume higher?

Are your main speakers set to large or small in the AVR? If large, try setting them to small.

There is no setting for that.
If i set the fronts to full band it allows the sub be set to double bass
I set all my speaker lvls to -12db and the sub to 12db
Just have to crank the volume more from -30db to 20db
It’s kinda solved my problem i guess[emoji53]
Unsure if this is the right way to go about it.
