Question about Audio Players & Recorders

1 Answer

JBL L820's cause my amp to shut off when turned up below low. The Yamaha amp code says check speaker and wiring. New wires did not help. I can put my Paradyms, Bose and other speaker on the receiver and it works fine. Where to go next?? Thanks!

More than likely the voice coil on the speaker or possibly the copper wires to the voice coil are touching.

When i put on power protect light come on


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible causes, do the following. Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still shuts down (goes into protect mode), the amp almost certainly has shorted output transistors and will need to be repaired. If the amp only shuts down when it's driven to relatively high volume, you need to confirm that you have sufficient power supply voltage. With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts on either the B+ or remote line, you need to check the wiring feeding whichever line is too low. If 'both' the B+ and remote turn-on lines are low and your battery is fully charged, you may have a bad ground connection.

The sound will suddenly go off on my Yamaha RX-V595 receiver. I can turb it back on and it will play for awhile and then turn off again


This is a classic over heating problem. There are 2 likely causes - hope for the first.
1. The speakers or wiring have a problem and draw too much current from the receiver. Carefully check your wiring. If it looks OK, leave both speakers disconnected and turn the volume control all the way down. Power the unit up. If it stays running, then try one speaker then the other (at low volumes to avoid damage) and see if one makes it shut down. If it does not stay running then see #2.
2. The power amp circuitry of the receiver has an issue causing it to overheat or the overtemp circuit is faulty and it thinks its overheating. Either way, this one needs professional help.
Good luck

Hi,

Try less speakers.
The impedance will be to low for this amp.

RX-V665 Yamaha reciever has been working great. Use it for surround sound and outside, zone two speakers. Recently started turning off during movies. I run blu-ray through receiver. When playing Star Wars...


You may find a solution by doing some of the things I have tried - see below

I recently puchased this model to replace an older Yamaha system that also had this shut-off problem. The new RX665 system has the same problem but I check the impedance setting using the instruction in the manaul anyway. The problem persists. I have check all speaker wire to make sure nothing was touching. I did find one wire touching on the center speaker but the problem persist.

Since the problem followed me when I moved and with a new amp, I am beginning to think I am have a speaker that's causing this - maybe the sub.

Internal wiring schematic for a JBL 4311 WX-A


the conductor xxx\blk is the minus or black( from speaker) the outher is positive\red pin from speaker) the woofer is bigest speaker inside is connected on the crossover at low output, tweeter at high output, if you connect wrong you can burn speakers and crossover, you can test with very low volume on amplifier.

1st connect low to woofer, it only her low freq below 500Hz like drums and bass, if connect on med out the speaker is working as handpocket old radio audio. if connect on high the speaker is like no audio out. (the woofer take about 60-75% of amp power).

2nd connect the midrange at mid output you can listen to human voice cristal clear. if connect on high output you listem like esteric female shouting.

And connect the tweeter at the empty output

Take particular attention on polarity terminals, if you exchange the polarity you have a moofle sound traped inside of speaker, and some structered box noise who may open the box panels in future.

I got a stock ford JBL amp with no wiring diagram i need to know what wires are what i have tryed to test for the power wirer but no luck.


ok on most amps there are two sets of wire ports one for speakers & one for +12v,grd & 12v remote start if you look over each port it will say what port is for what wire if it is in a connector it gets slightly more complecated what you do is with a vm check from wire to chassis ground [like seat bolts] 12v with key off when you cet power isolate wire then turn key on till radio comes on then do the same test for 12v isolate that will be remote start then turn key off &check from the first wire to other wire for ground to find speaker wires connect a regular peace of wire to chassis grd & touch the wires you will here the speaker pop be sure not to hold the wire on long cause it will blow the speaker

I have a new RX V661 7.1, shuts down when I turn it up.


How much loudness are you trying for. Also, the program material and bass/treble settings factor in when asking a system for increased power...accordianman

My Yamaha HTR-6050 shuts off at random times and says "Check SP Cable"


That is a check the speaker wire error, caused by a short or perceived short. If you look at the back of the receiver you may see 1 strand of the wire loose, they are very hard to see sometimes. You may use banana plugs as it is painful to get everything hooked up without a few loose strands.

If there is still the issue check your speaker connections for the same issue. If they are in ceiling/wall speakers disconnect them all then plug them in one at a time to narrow it down.

If the issue persists perhaps one of your speaker wires has a short somewhere, could be a misplaced drywall screw from hanging a picture, or a carpet tack strip, or a pet deciding it was a nice chew toy.

If you are completely sure it is none of those then I would say it is a bad speaker or receiver. Try changing in and out known good speakers/receivers if you have access to them to see which one it is.

Good luck

Kenwood 7202 Amp that is blowing fuses


If your speakers are wired for an impedance below 4 ohms mono or 2 ohms stereo, that would make it shut off. If you have a speaker wire shorted to ground, it would also cause the amp to go into protection.

 

If the speakers are not the problem, it may be shutting down because the voltage at the amp is dropping too low.
