When i turn on my Samsung HT-C550 IT showing PROT and DVD turn off. What this is mean PROT?


PROT means that the AMP is protecting itself from damage due to bad or incorrect wiring or damaged and or incorrect speakers. Check your wiring and speakers.
If you find no problem then, DISCONNECT YOUR SYSTEM FROM THE POWER, disconnect your speaker wires...all of them, then reconnect the power ONLY, turn on the system and see if it still says PROT. If it does then your amp is damaged.

Marathon 2000 amp... PROT light


Ok this means the AMP is in protection mode!..most likely the cause is a short in your wireing from the speaker wires! check all wires going in and out of amp! Look for stray wires touching metal or other contacts! (If this does not fix it the short may be inside of amp!
(This has nothing to do with a fuse!)

RED Port light on AMP?


are you sure its not PROT?
the amplifier is protecting itself from fire because of something.
Disconnect the subs. and turn on.
if it comes on normally, the subs are at fault and will need attention. If the light still stays on, you hafe probably blown an output on the amplifier and it will need repair.

Coustic 601se power on but bad sound


This is generally caused when there are blown output transistors but that generally causes the fuse to blow or causes the amp to go into protect mode.

If you connect a 15 amp fuse in series with the main power wire and it blows when remote voltage is applied, the amp is drawing excessive current. The problem could be either in the power supply or audio circuits.

Do NOT apply power without having the transistors clamped TIGHTLY to the heatsink. They can fail in seconds when there is a problem. The heatsink helps protect them.

Protection light


Hello. First, disconnect all of the speakers the amp is driving and the rca inputs while the amp is off. Now power on the remote. If the prot. light still stays on you will need to varify that the voltage across the ground and b+ terminals is a minimum of 12 volts. If this is true than your amp may be damaged due to shorted parts. Otherwise, try to repower the amp while a speaker is connected and if it is O.K. than there may be a problem with the RCA ground in the head unit or the amplifier. We service these amps at Sound Repair 321-690-0808.

Prot. light at High vol. (forget Bass CD)


You may have the speakers wired for the wrong impedance.

How many ohms per voice coil?

How many voice coils per speaker?

If the speakers are DVC, are the coils of each speaker wired in series or parallel?

Are the speakers bridged on the amp or one per channel?

No audio-amp protect light come on then went


You need to check the DC voltage across the B+ and ground terminals. You also need to check the DC voltage across the remote and ground terminals. If the voltage is less than 11 volts, you need to check the B+ supply and remote wiring for breaks or open fuses. You should also check the ground connection to confirm that it's not loose.

 

If the voltage is OK, the output transistors are likely shorted.
