Re: sound problem

I found out that it was simply my speaker connection. That is, it seemed like a good contact, but in fact the stero was reading "pulsing" from the speakers and shutting off to protect itself. I simply cleaned off the wires and carefully reconnected them.

Why does my system cut off when there is a loud noise?

By loud noise I assume you mean in the movie you're watching or the CD you're listening to.
That's the protection circuit kicking in. Depending on how you have the player configured (audio levels, effects, mode....etc) it can "overdrive" the outputs and cause the protection circuit to energize.
If this happens a lot try changing the audio mode to something a little less (change speaker levels to a lower number, no bass boost or at least not as much, etc.).
Good luck.

Vizio sound bar model vsb211

It might be clipping so just try turning it down. If you usually listen to it loud it might have blown though. The problem also might be your power supply if it cant keep up with the power needed for the speaker

My subwoofer shuts off when I turn it up too loud. How do I fix it?

Don't turn it up so loud.
Or get a bigger subwoofer.

It's got a junk 6.5 inch speaker and the amp barely does 50 clean watts.
Claims 167 Watts at 10% distortion - impossible when it is drawing 160.
Drive it too hard and protection circuit will cut in and shut it down.

Protected in short means that the amp is no longer powering the speakers due to one of the following: 1. Volume is up too loud 2. Equipment Failure 3. Dirty power
Turn amp on by pressing the function button on the remote of a source that has nothing on it or is not powered on. If it still says PROTECTED even though you are on a source with no sound coming in, then the equipment is in need of repair. If it simply comes on normal displaying the source turn the volume down till it says MIN. Find the range of your speaker and amp power by selecting a source with music or movie audio and slowly turn it up till either its too loud or says protected. Be sure to double check all speakers and wires to ensure wire integrity as well as proper connection.

Outside bose speakers keep turning off after a few seconds

It sounds like the speakers are either peaking and shutting down or they are dodgy. Check the volume going into the speakers and turn it down see if that works, otherwise take the speakers back. It might be worth trying a different set of speakers as well

We have a dbx Driverack PA unit with a Crown CDi1000 amp in our church. Recently, we starting having problems with the output to our main speakers dropping out. We found (by accident) that if we unplugged...

Check the speaker wires coming out of your amp. Chances are you have a problem with a speaker wire and this is just a coincidence. I say this because the same thing happened to me during a live show and I about had a heart attack. We lost the front of house for about 15 minutes while I tried to troubleshoot the Driverack, the board, and everything but the speakers and speaker wires. The cables were a recent purchase and were premium grade with light wear so I mistakenly ruled them out. It was intermittant so it took me a while to figure out. Now I understand that that's the weakest link in the chain and from now on I start there and work backward through the chain (that is, if all sound is cutting out).

Do you use banana plugs (two metal pegs sticking out of a plastic rectagle) coming out of the back of your amp? There are little screws inside the holes on the back of the banana plugs. Those can vibrate loose, especially if they're just factory tight. Get a little standard screwdriver and tighten them down. That will probably solve your problem.

Okay, wait a minute -- could be one more thing. You mention that the loud popping can be heard. Do you have any gates turned on? Most compressors have gates. Check your compressors to see if you have your gates turned up too high. A gate set too high would allow the loud pop to go through to the PA but would cut off everything low to mid-volume.

I guess you can see that I don't think it's a problem with the Driverack. I don't work for dbx or anything, I just think these other things are far more likely than a problem with the unit.
