Samson Auro D412A Speaker PA Active Questions & Answers
1 Answer
Hi,
I have one Samson Auro
If you read the TRUE specs on this speaker it is really a 200 Watt RMS unit. Make sure you are using balanced lines to the speaker XLR or TRS cables. The mixer should NOT be a passive mixer as these do NOT generate true balanced lines. Make sure the mic can't "hear" the speaker or you may be getting supersonic feedback that is above your hearing range that saturates the amp. If *********** can't stand to be ain a 15 foot square room with teh level you are generating, it is TOO loud for this unit to handle.

After working great for over
This is a bi-amped speaker. That means it has a separate power amplifier driving the bass woofer and treble horn. They have a low-level electronic crossover to separate the frequencies to the appropriate speaker. The electronic crossover is the least likely to fail... so you need to do a test:
You will need to open the unit and using an ohmmeter check if the woofer speaker voice coil is open or has continuity...It should be around 6 to 16 ohms. If it is above that, the speaker itself is blown and will have to be replaced. If the speaker has continuity, then the bass amp has failed and will require repairing by person that is adept at electronic repair. Before opening the unit you MIGHT be able to diagnose whether the speaker itself is blown by seeing if the woofer generates a thump when power is turned on or off. If it does, then likely the speaker is OK and the problem is the amp, otherwise the tests above need to be done. Usually these plastic cabinets are held together with seveal scrwes from the back. Some are in :deep "wells" and will require a very long shaft phillips screwdriver... and they often are long screws that wear one out unscrewing them. A genlte pry after removing the screws will separate the back and the front.

What do I need to
Connection all depends on what type PA system you have. Here are the rules: Power this device from the SAME receptacle your mixer is powered by, even if it means running an extension cord. Use ONLY a balanced line from the mixer... either TRS cable or XLR cable.

Samson MDR8 blowing internal power supply fuses.
Here is a troubleshooting hint:
Put an incandescent lamp in series with the hot side of the power cord. This acts as a resetable fuse while troubleshooting so you don't blow fuses.
Schematics are hard to come by, but power supplies are easy to trace the circuitry.
Check filter caps and the diodes and THEN look for hot (temp) IC's and transistors.
