Maybe you have defective speaker! try to cut out your speaker from the amplifier then you power on again! if the protection is in again you have defective power output! transistors or mosfet transistors.

I have a s1500 samson amp I keep blowing speakers, what can I do to prevent this from happing again? The speakers that blown first was two 12'' yorkville 350 w impedance 8 ohm, the next speakers that blown...


Turn the volume down? Feed it cleaner source material?

You don't say under what conditions you're blowing them or if any of the informative indicators are warning you of impending doom. The Samson is capable of cooking just about any home speaker.


The following conditions will cause the Protection LED to go on:


Initial power-up: For approximately five seconds after initial power-up, the

protection circuitry is activated and the speaker output is muted. If everything is

operating normally, you will hear an audible click at the conclusion of this brief

period, as the protection circuitry is deactivated and the S1500 / S2000 begins

delivering signal to connected speakers (at which point you'll hear a click). It is

normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the S1500 / S2000 will cause

the protection circuitry to be activated (and the Protection LED to go on)

whenever the operating temperature of the unit rises above a safe level. To

guard against this problem, make sure the S1500 / S2000 receives adequate

ventilation on all sides and that both the front and rear panels are unobstructed.

Severe overcurrent conditions: This occurs whenever the signal being input to

the S1500 / S2000 rises to a level above 20% THD (Total Harmonic Distortion).

Shorted speaker cables: This will occur if, due to faulty wiring, the hot and

ground signals being output by the S1500 / S2000 short one another.

Output impedance drops below 2 ohms: This can occur if the S1500 / S2000

is connected to inappropriate speaker systems (see the "Setting Up and Using

Your S1500 / S2000" section on page 5 in this manual for more information).

DC voltage detected at speaker output: The most likely cause of this is an

internal failure.

In general, any time the Protection LED lights up (other than during the

approximately five seconds following initial power-up), there is reason to be

concerned. If this occurs, turn the S1500 / S2000 off immediately and carefully

check all wiring and external devices in order to locate and correct the condition

that caused the LED to light up in the first place.

For further assistance, contact your local Samson dealer. If purchased in the

United States, you can call Samson Technical Support (1-800-372-6766)
between 9 AM and 5 PM EST.

No sound coming with protection light on


It's either overheated or you may have faulty speaker wiring or a shorted speaker. These directions come from a Samson servo 120a but the theory is the same.

The following conditions will cause the Protection LED to go on:

Initial power-up: For approximately five seconds after initial power-up, the relay

speaker connection circuitry is deactivated and the speaker output is muted. If everything is operating normally, you will hear an audible click at the conclusion of this brief period, as the circuitry is activated and the Servo 120a begins delivering signal to connected speakers (at which point the Speaker LED will light if the Speaker on/off switch is in its "in" position). It is normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the Servo 120a will cause the relay speaker connection circuitry to be activated (and the Protection LED to go on) whenever the operating temperature of the unit rises above a safe level. To guard against this problem, make sure the Servo 120a receives adequate ventilation on all sides ; in extreme environmental conditions, you may also

want to consider the use of cooling fans.

Severe overcurrent conditions: This occurs whenever the signal being output

from the Servo 120a rises to a level above 20% THD (Total Harmonic Distortion).

Shorted speaker cables: This will occur if, due to faulty wiring, the hot and ground signals being output by the Servo 120a short to one another.

Output impedance drops below 2 ohms: This can occur if the Servo 120a is connected to inappropriate speaker systems (see the "Setting Up and Using the Servo 120a" section in this manual for more information).

DC voltage detected at speaker output: The most likely cause of this is an internal failure. In general, any time the Protection LED lights up (other than during the approximately five seconds following initial power-up), there is reason to be concerned. If this occurs, turn the Servo 120a off immediately and carefully check all wiring and external devices in order to locate and correct the condition that caused the LED to light up in the first place.

My phoenix gold x200.4 amp turns on but the protect light keep on flashing


  • What does it mean when the LEDs flash on my amplifier?
    With most recently produced Phoenix Gold amplifiers, a flashing/blinking LED is an indication that the unit is in protect mode, usually due to an overcurrent condition caused by an internal short, external short (speakers), or low impedance. Overheating will also cause the amplifier to shut down temporarily.

    If amplifier remains in protect mode, power down the amplifier, disconnect the speakers, and power up again. If LEDs continue to flash, there is probably an internal problem with the amplifier that will require service attention to fix.

    I have two zeus 1000 watts amps four rockford fosgate phase 2 15 inch woofers why my protect light keep coming on when i turn up my radio up


    The power draw may be eccessive, try placing a capacitor (or a bigger one ) on the lines to the amps.

    Red status Light


    If the protection LED is lit, the amp is in protect mode and probably has shorted output transistors. To eliminate other possible causes, read through the following page:

    Question on BB2125 2 Channel Amp


    Hi jgoudie

    It is a signal sensing turn on unit, so will not turn on until you have supplied signal to it. Plug it into a signal source and see what it does. But unfortunately, in my experience the protection light coming on means there is a fault in the amp.

    You can download the user manual for the amp from here. Click downloads in the middle of the page:)

    My amp is on but the protection light stay's on!!


    Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.

    Amp has Red LED light on.


    Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

    American pro amp 1000 watt vs=3503


    The Protect light would normally be Red. You need to test your RCA's and make sure your getting a signal to your amp.  I would just buy a new set  or if you have another set just try them.  If you get your amp to power on and all of your voltages are right with the proper signal and your amp fails to turn on you Have a bad amplifier
