Mt jesen A600HLX is stuck in protect, i dont kno whats wrong with it other then i was told i have blown a channel... i brought it to a company to fix it and they said they cant do anything without a schematic, ive searched evvveeerrryyyywhere and i couldnt find one, i like this amp alot even tho it might not be the best in the world, it was a strong amp. id hate tosee it go in the trash so could u please send me a schematic for my amp. or send the technician the schematic. or just tell me how to fix it if possible. thanks alot - tom

Re: my amp went into protect

And they shouldn't need a schematic unless they can't read the part numbers of the fried components.

How are we to even know what brand mixer you have... and have you tried it using your CORRECT adapter. Most mixers are pretty well protected against using wrong adapter. Many require an AC voltage input rather than DC and use of a DC adpater will not damage one unless the voltage is very high.
Turn down the volume or power settings on it since its pulling too much power and shutting off for a few sconds to keep from blowing. Depending on the amp and speakers your using dont bridge the channels. If it won't come out of protect mode then unhook everything and just hook power, ground, and remote and wee what happens. If it comes on again and stays on then amp is blown.
dear friend-as you say the fuses are there to protect these devices,but sometimes things goes wrong.it appeares that the output channels on you stereo is blown,you will have to remove and have it checked.
Sounds like the out put stage of the amp is shorting, They are either 4 large transistors attached to an aluminium plate (heatsink) or one large chip with heatsink. also sounds as the driver stage went too when you switched it on the second time. If you know nothing of electronics I suggest you take it to an audio repair shop, as it is cheaper to repair than replace high power amplifiers.
I do believe this is caused by one of your amp fuses. Depending on which + on the amp is being used. That channel has a blown fuse. have you tried running + and -, + and - to both channels to see if both subs worked? If one sub doesn't then it's a blown fuse or scarred fuse and needs to be changed.
Most if not all CB radios have a reverse protection diode soldered immediately right after the power connector. Its purpose is to provide a practical short if the wires are connected wrongly to a power source. This would cause the fuse to blow. The diode normally goes bad after a reversed polarity connection and therefore would need to be replaced. This diode is not in series with the B+ line but connected parallel to the power.
In some instances, other components would also fail: Power capacitors, Audio IC, TX finals and/or the switching/regulator IC.
Hope that this be of some help/idea. Pls post back how things worked out or should you need additional information.
These solid state amps have no user serviceable parts inside them as everything is soldered into place and your gonna need to know how to use a multimeter to trouble shoot the parts inside the amp on the printed circuit board. Sorry But without the proper training and the right tools you could cause more damage to the amp if you dont know what your doing. You cannot just open the unit and see whats bad. You must test each suspected bad part and replace it as needed. You should take the amp in to have a pro look at it, as there is no easy fix on these unless its an external fuse, and a fuse will very rarely blow all by itself. Good Luck
