Bass Control Knob question
 

I have a JL 500/1 amp and I just receieved the remote bass control knob in the mail and when i connected it and tried to change the bass level, nothing happened. Is there anything I need to do on the amp to enable the control knob? I thought all I had to do is connect both ends and it would work immediately.

Thanks

you will probably have to adjust the gain on the amp to notice a difference.

It seems that the remote bass port is broken on the amp. I have tried several different remote knobs and none of them make a difference. Anyone else experience the same problem? Can it be fixed?

Have you tried different phone cords?

The JL knobs aren't the normal massive bass boost knobs that other manufacturers have put out in the past. They are a bit of a tuning tool. The section where it plugs into is where the magic happens. The knob only gives the bass a little control.

The problem is that I notice no difference whatsoever when i connect the knob and rotate it. My 500/1 amp has its gain turned all the way down and I thought that might be the reason why the knob doesnt work but I tried turning up the gain and the knob still has no effect on output.

Defective amp?

Did you slide the switch that turns the bass EQ on? It should be just to the left of the bass knob jack. You also have to adjust the boost level.
