Question about Acoustic Research AR PR1212 Subwoofer

Open Question

Acoustic Research Subwoofer cuts out

I have an Acoustic Research PR1212 subwoofer, it will not go into standby mode and it now is shutting down during high impact events in movies.The blue standby light will go out and no sound for only a second or two and then it comes right back on. I thought about bad connector on the end of my monster cable but I have another one and tried it, same thing happened. If I turn the volume down on the sub then it quits doing it, but I would think I should be able to turn it up past 1/4 volume. Not blowing fuses, just shuts down when it shouldnt and stays on when theres not any signal. Thanks

    I been having the same problem about it cutting out at high volumes, but mine goes into standby mode after inactivity with no problems. I have a friend that is going to help me figure out the problem with the amp, but we have not had a chance to work on it yet. I will post again if we are able to figure it out.

SOURCE: Hello, the auto on on my acoustic research pr1212

No sound from sub, pilot light on, distortion only from volume control when rotated, fuse good. In the past, rotating or jiggling of volume control would correct problem

What makes you feel that isn't right?

You can't just slap a sub onto a receiver and have it work optimally (if at all). The receiver must typically be configured to know it has a sub, then bass managment and sharing decisions must be made, then crossover frequency choices and levels adjusted to match it all up.

All self-powered amps work that way.

Have you looked at the manual for your JVC?

My AR-S115PS Subwoofer keeps cutting out. Especially at high volumes. I've never had this problem before. What should I do?


check your speaker impedance by multimeter normally speaker ohms range from 8,6 or 4 ohms see your speaker spec. possibility speaker short, so impedance become too low when driving with strong bass become over current and cut out. if this is the problem the only solution is change the speaker only.
