I have a YORKVILLE AUDIOPRO 1212 mixing board. When I turn it on the PROTECT power LED light comes on and stays on (does not go off.) What can the problem be?


That's your Amp Protect. Only a Yorkville certified technician can help you now. Email Tom Keefer at tkeefer@yorkville.com for a return authorization number, then mail it to Yorkville. They'll fix the problem.

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.

Can one(1) Peavy PV 2600 amp provide enough power for two(2) Yorkvilles 15" 300W full range and two(2) Yorkvilles 18" 400W subwoofers?


It should be able to do this. You would need to put each type speaker on a seperate side and then use either an elctronic crossover or an EQ set to pass only lows into the side for the subwoofer to block sending highs to the subs.

Facing problem-(WAP54G)


Try the following steps:

1. Disconnect the WAP54G power adapter.

2. Reinsert the power adapter directly into the wall socket.

3.Remove any power strips or surge protectors temporarily to ensure that these items are not preventing the WAP54G proper operation.Note: Make sure that you are using the power adapter that came with your WAP54G.

4. Plug the power adapter into a different wall socket in another room.

5. Press and hold the reset button for 1 minute. Release the button. Then turn off the WAP54G for another minute. Then turn it back on.

6. If the power light is still red, then you will need to replace the WAP54G.

Red protection light wont turn 2 green no matter what so the amp wont work


Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.
