20 Most Recent Samson Auro D412 2Way Active Speaker Questions & Answers

The volume setting on the speakers has LITTLE to do with how hard you are driving them. Your source might be extra hot and overdriving them. Read the specs on the speakers and use a sound meter to check your level. The speakers, being only 12 inch, should fill a room 20 foot by 20 foot to about 95 to 100 Db which you are only allowed 2 hours in MAX to prevent hearing loss. At 6 hours you should keep it down to 85 Db SPL. I know several deaf musicians that were exposed to high sound levels in rock bands... a deaf musician is kind of washed up.

You can safely connect your powered monitor speaker to either the monitor output jacks or the tape output RCA jacks on your XP510. In addition, you may download the owner's manual here: https://www.manualslib.com/download/515708/Samson-Expedition-Xp510.html

Which amplifier specifically?

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.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring. This assumes there is the correct level of signal entering the input sockets of course.
