Event TR5 Monitor... is it broken?

Post by (DC) »

I have had a pair of TR5 monitors for a while and they have worked great for me. Today I turned them on and ran pro tools and the right monitor didn't seem to be playing. I checked everything, I switched cables, and even flipped around the channels coming from my Digi 002. The signal chain is fine.

The problem is IN the monitor.
I'm wondering if I blew a fuse... if it even has one. If it doesn't I have a bad feeling a messed something up on the card.

When I turn the monitor volume all the way up I can hear the audio playing softly. Then, all of a sudden the volume popped up butt there is still a whole lot of "fuzz". Is this a case of bad wire contact or something else? Has anyone experienced this kind of problem and do you think it would be too expensive to have repaired?''

This problem has been annoying me a lot... So any helpful suggestion/response would be great.

Thanks!

It's not clear which end of which cables you switched; but overall the symptoms sound like a bad connection. If you haven't already, try removing the speaker cables completely and using the other cable (swap the entire cable so the cable for the left speaker now feeds the right one)

If you just swapped outputs at the digi-002 box, then the connection at the speaker itself could still be bad. Also, the actual connector on the speaker could have corrosion and cause similar symptoms.

Play with it a bit more, and keep track (and notes) of EXACTLY what you did and what the results were. You should have the volume controls turned down lower while doing all this... Steve

The symptoms do not change when I switch cables, switch outputs, and switch cable and outputs. The fuzz noise occurs even when I don't have the speakers connected, and only have them on.

This sounds to me like a bad connection INSIDE the speaker; if it wasn't working at all, you'd get NOTHING out. No fuzz, nada. It also could be a bad filter capacitor in the speaker's power supply, or a bad solder joint in that area of the circuit.

If you're up for a little adventure, (I've not worked on these particular monitors so bear with me) you could remove the amp's cover (power cords DISCONNECTED, please) and look for any loose connections (the intermittent part tells me this may be so) - if there are no obviously LOOSE connections, next I'd look at any and all solder connections (especially on the input to the amplifier) - check solder joints to see that they're physically tight, then look at the solder itself; if it's shiny, it's probably OK. IF it's kind of a dull silver, or uneven in color, it may be a "cold solder" joint.

If you see one that's dull, and you have a soldering iron (not over 50 watts, no "plumber's guns" here) you can try heating the iron til it's as hot as it gets (usually about 10 minutes or less), then clean the tip (wipe it on a clean rag, QUICKLY) and apply a bit of fresh solder to "tin" the iron, then hold it against the solder joint til the metal "flows"; just as it flows (gets liquid) count "one thousand-one, one thousand-two", then remove the iron from the joint and DON'T DISTURB IT TIL IT CHANGES "SHEEN", or 10 seconds, whichever is LONGER.

Put the speaker back together and see if it's fixed.

Because the speaker "gets louder" occasionally, this sounds to me like it's an INPUT problem - that's why I started with the input side, but you may need to follow All the connections thru the circuit, including checkout of all solder joints on any PCB's you find.

Good luck... Steve
