SOURCE: Can I blow my speakers

Hello,
Yes you can. If you have enough power and your speakers cannot handle it than you can blow them.
If you turn up the volume high enough to hear them start to distort, than its probably a good idea to stop there because if you go much further than yo can blow them. Another good thing to check it the power output of the amp and the power capacity of the speakers. This will give you an idea of what your system can handle.

My NAD T747 keeps shutting down in Protection Mode at 6db when it used to go much louder. I cleaned the unit. Still nothing.


Modern AV receivers such as your NAD have protection circuits to prevent damage when there is a short on the speaker terminals. Look carefully at the speaker connections on the back of the AV receiver- for example, the speaker cable for front left speakers labelled + and - : there should not be any stray strands of wire that connect from + to - ; this would be a short circuit. Check each of the connections on the AV receiver as well as on the back of each of your Speakers themselves. Also ensure all connections are snug (do not use pliers). If this does not solve your problem, you may need to take your AV receiver on for a service checkup. Good luck !

Autotek sx2150 keeps going into protect mode


check to see if all the speaker connections are in polarity ( all + to + connections and all - to - connections in their corresponding places)

also you could check to see if the speaker cables are not exposed and touching any metal surface from the amplifier to the point of where the speakers are installed, any contact would cause a short and force the amp into protect mode.
hope this helps, need any more help let me know

Noise, I get a buzzing noise out of my speakers when i hook up my interface with a jack cable any help ?


If the buzzing is louder or softer, directly relative to the volume level, it is signal interference.

99% of the time, when you get the buzzing or "air" sound, it's the cable. To give you an idea of how serious this is, each of my speakers has a Monster THX Ultra 1000 speaker wire running to it, which can cost roughly $100.00 each. This is for the sole purpose of eliminating that air noise or buzzing.

When running speaker cables or AV cables, you don't want them to run parallel to each other, unless they are several feet apart. If they have to cross paths, you want them to cross perfectly perpendicular to each other so as to minimize the amount of contact they may have.

Speaker wire should also be twisted copper (unless running fiber optic cable, which would be extremely rare). Many people try to use solid strand, but a lot of the signal is lost, even when well insulated.

If your speakers are close to anything electronic, try to move them away from the source, or move the source from the speakers.

If you have a GSM phone, the phone can cause distortion in your speakers as well, but with the newer phones, that only happens when it reverts to the older tower technology.

It could be the source of your sound input as well. If you have a bad connection at the source (assuming your computer?), or the source itself just isn't a very good quality, this can also cause that buzzing or air sound.

Hope this helps.

I touched speaker wire from the receiver to hot wires on my subwoofer and everything shut down, now the receiver will not power on. When I push the on button I get a click noise, but if I keep trying to...


When the speaker wires were shorted it would have damaged the output and so there is a short in the output circuit thereby the amplifier goes into the protect mode. So remove the power and the speakers, reset and test again without the speakers. If the amp goes to the protect mode then you need to have assistance to check the boards within for a short. sometimes it is difficult to probe for a voltage check and so will need jigs to test.
Check the output drivers for short using a multimter, check for the rail voltage to the outputs or there can be a power issue.

Crysler lhs, static buzzing noise in speakers when accellarating?


This is usually indicative of a ground loop causing noise from the vehicle electrical system. Long story short your stereo isn't grounded well enough.

There are two possible solutions:

1. Ground all components to the same point. This will reduce the potential and should greatly reduce any noise.

2. If number 1 is not possible (and it often is not), use a "ground loop isolator", available at nearly all electronics stores, or car audio suppliers. This device prevents a direct electrical connection between the two sources and will usually fix the ground loop.

Try a different monitor or this monitor on a different computer. If it makes same noise on different machine or new monitor makes no noise on your machine you need a new one.

Have the place you bought have a look at it and at the smae time turn on te vibrate mode. No. there is no way you can put in louder speakers for now. If you did find one pls be wary that it would void the existing manufacturer's warranty
