Txm20 samson ... unit wouldnt turn on... where is the fuse ?

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:

These are passive speakers, so if there is a fuse at all it will be as a high frequency protection circuit on the crossover.

Are you an experienced tech? In most cases (unless there is a defect in manufacturing) transformers are not a common cause for failure. If it blows the fuse disconnect the secondaries and see if it still blows the fuse. If it does then the transformer is likely the cause, if the fuse doesn't blow then the problem is elsewhere. If you have 120vac at the primary and nothing(or very low) at the secondary(s) then the transformer could also be at fault. If you have done this already and narrowed it down to the transformer, sorry I cannot help. I used service Samson but no longer am able to get parts. Good luck!

hi, my samson xm610 have a problem even i tern off the voluem of each chanel still have a sounds be fore is not just like that.. can you help me

Change internal fuse on battery. Unit will not work unless battery is connected but battery needs fuse to be good

Have you checked the cables? If that doesn't fix it, you probably have a loose connection inside between the "mixer" unit and "amp" unit

Hi there. Just in case you haven;t got it, here's a link to the TXM 20 manual:

If you have this, then let me know what controls your are having porblems with and I will try to help>

Most common reason probably would be incorrect or failed power adapter. It appears the unit requires a 18 VAC (not DC) adapter. Dead batteries if that is the power source would be the other cause to suspect.

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.

try this;

1.using different usb inputs on your pc desk top
2.update drivers on both your desk top and laptop
3.using a different usb cable

if it works fine on your friends computer most likely its not the mic
