Question about Pyle PZR-1000 Amplifier

1 Answer

Reset button I have a PZR-1000 amplifier and it doesn´t work , on the manuals suggest that the problem can be by the protection circuit, and it can be solved pressing the reset button. I´ve tried to find this button on the back of the amplifier but I couldn´t find it. Please tell me what can I do to reset it. Thanks in advance. Camilo

Without owning one , I checked the manual and, sure enough, there's no circuit breaker shown. I mailed tech support. Meantime check where the AC comes in and the fuse holder ( unplugged) and see if you can find anything.

Error code e02 kenwood amp on sony xplode 1000 watt subwoofer box


It is possiblethat the amplifier had encountered a fault with a higher current drain whichhad triggered it to a protection fault condition. The fault can be with youroutput drivers. Please check for short on the outputs fitted for both the channels.Use a meter after disconnecting to check for short in the drivers. Disconnectthe positive and negative voltages to the output and see if the protectchanges. Even a fault in the preamp stages that drives in high current into theoutput can shut the Amplifier. Sometimes this can be a noise which can be a HUMor HISS before the protect works. Faulty capacitors in these circuits also cancause similar issues and needs close observation.You need to confirm andreplace the specific stages or outputs. If not there can be issues in themother board. Maybe the protect circuit by itself is shutting off due to afaulty bias or there is a leak in any voltage/current sensing circuit. Alsodisconnect the speakers and test, if the amplifier comes out of the protectmode then check for short on the speakers.

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.


Hello
Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

SAMSUNG HT X30 SHUTS DOWN WITH" PROTECTION"


It's a known issue with samsung Home Cinemas. It has to do with the cooling of the device and other related issues. One of the bellow could solve the problems.
First thing is to reset the device:#1 - Make sure there's on dvds in the system
#2 - Put it on stand by
#3 - Hold down the STOP button on the UNIT
#4 - HOLD until you see the stand-by light flash
#6 - This has now reset the system

If that doesn't work try to do a firmware upgrade http://www.samsung.com/in/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=&prd_mdl_cd=&prd_mdl_name=HT-X30

Amp wont get out of protection


Most likely you'll need to do a hardware reset for the chip to reboot its internal memory. You most likely got a spike in current through the 'brain' of the circuit and locked up the interface. You A) could search the enclosure for a small soft touch button, or B)open up the contents (risk this may void warrantee) and find it on the internal circuit board, or C)check the manual for suggested method. But more realistically, you need to check your system to determine what caused the initial case.

Your amp needs to be serviced. Bad protection circuit. Take it to a local car audio shop and have them bench test it first to be sure. Hope this helps.

I think you will find that something has failed and is causing a short circuit, that's the reason the fuses are blowing and not because you are fitting the wrong type.
I should look at the main devices (anything on a heat sink) first. If they are transistors, you can test them with a Ohm meter. If it gives a reading as if the transitors was acting like a piece of wire, it's gone.
Sometimes you might see evidence of burning or even a hole in something.

Amp protection circuit has been activated


sometimes the protection circuit will enable because of a bad speaker i would suggest taking the load off of it by removing the speaker wires and turning it back on. if it stays on take an ohm meter and check the speakers should be between 2-4 ohms load.

I stop getting power or sound to my sub


Double check your fuses. It sounds like you blew a fuse. Check the fuse for the radio aswell as the inline fuse for you amp. On some amplifiers there is a circuit breaker reset button. Check to see if your amp is equiped for that. I did find this quote for reset out of the owners manual.
Remote Turn-on
Automatically turns amplifier on when connected to the head unit's remote output. The
amplifier will turn on and off with the head unit to save current consumption. This control
also operates the reset circuit for the amplifier's protection. It must be connected with
the head unit in order to reset protection circuits.

Sony xplod 1200 watt amp quit no kind of protect lite on please


short answer yes... Long answer... Amp Failure: There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure. Transistor Failure/Checking Transistors: In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals. Note: I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit. It is most likely the power supply that has taken a ****.
