Mar 26, 2008 03:44 pm Something could be messed up with the capsule on the mic. Do you have a different mic to try? Also, swap out the cable to see if that is it.

i just bought a cad trion 8000 tube mic. i recorded with it for the first time last night. it sounds awsome, everything was going fine, and all of a sudden the volume spiked and got crazy loud and started clipping out. i tapped the head of the mic and it stopped. this happned 2 times in an hour. i am running the mic through a yamaha 10/2 mixer, out throught the record outs into my cpu sound card. everything sounds great. i just cant figure out what is causing this. -joep

Mar 26, 2008 03:53 pm yeah you need to be sure it's the mic first, so try the exact same set up with another mic or two, then another cable or two, and every cable and connection on your signal chain. It sucks, but it'll pinpoint the problem.
Mar 26, 2008 05:11 pm yeah that sounds like a good approach. if thats not the problem i was going to change out the tube, but that will void my warranty ruining any chance i have of getting it repaired or replaced for free. this sucks.
Mar 26, 2008 05:17 pm yeah before you void any warrenty, make sure it is indeed the mic and not something like a cable or bad input or something.
Mar 27, 2008 03:34 pm figured out it was the fuse. last night i went to turn on the ps and it wouldnt turn on. i changed the fuse and it blew right away. i put in a better, beefier fuse of the same volts and it works like a charm. all the volume issues are gone. i recorded vox for 4 hours straight last night with no problems. the mic actually sounds better and louder at lower gain levels now. thanks for the help. -joep
Mar 27, 2008 03:45 pm Blowing fuses is a sign of a problem. The fuse is doing exactly what it's supposed to do: die a quick death, to protect the more spendy parts.
This is a sign, that you need to put that mic back in a box and send it back to be replaced.
For future reference, fuses are rated by the amperage they can pass, not the voltage. Just because the voltage is the same, doesn't mean the amperage is the same.
Putting in a beefier fuse just lets more amperage get to the sensitive components, then you will void the warranty and be left with a spendy paperweight.
Mar 27, 2008 07:59 pm i just got a second opinion. he said the same thing. a faulty fuse. the fuse that came with the ps was cheap . the fuse i replaced it with was out of a guitar amp. g amp fuses are built better to withstand power being pushed almost to its peak on a daily basis. he said the power surge probably caused the fuse to be damaged and subsequently fail. the tube and its connections are fine. if they are both wrong, the problem is probably within the power supply. i hope they're right. thank you guys for all the help. -joep
Mar 28, 2008 11:28 am Your logic is flawed.
Fuses are fuses. They are built to withstand a certain amount of current, then blow. It makes no difference what device they are in.
There is no distinction between guitar amp fuses or tube mic power supply fuses.
There is, however, a distinction between fast blow and slo-blo fuses. The manual should instruct you as to which should be installed.
There should be a rating for what fuse to use. Obey this rating, and put the correct value fuse in there: Current & Volts both.
If your power supply did something to blow the factory installed fuse, then again, something is wrong, and I would have it replaced right away.
Why tempt fate? Warranties are there for just this occasion.
Mar 28, 2008 01:00 pm It may not be the mic but there is definitely something wrong. At any rate if the fuse is the proper amp rating you will find out soon enough. If it's not, you may end up losing the mixer and the mic.
Mar 28, 2008 03:53 pm yes the fuse was a sloburn. i was told to replace it with the exact same fuse except fast burn so i knew if there was a problem right away. th eold fuse was cheap. the new one is not. after 3 people have checked the mic out, they all have come to the same conclusion. bad fuse. all i have to go off is what ive been told by the people who have seen my gear. if i do have any problems in the future i will send it back since it is still under warranty. im not saying any of you guys are wrong. i just have different people giving me different advice about a broke mic that doesnt seem to be broken anymore. my explanation is skewed because im trying to relay info between multiple parties that is very new to me. thank you guys very much for the help. if i have further problems i will definately take your advice. i even talked to cad about the fuse and got their info. also making sure that changing a fuse wouldnt void my warranty. thanks again- joep
Mar 28, 2008 03:58 pm Good deal. Glad you got it figured.
Didn't want to see someone overlook a potential problem.
Sounds like you're in good shape.
Mar 28, 2008 05:05 pm i really dont see a need for sarcasm here. i asked for your advice and will keep it in mind. i also thanked you for your advice and time, and did such with no attitude or ego. i had to make a descision based on 5 peoples opinions and decided to go with the professionals who actually had time to inspect my gear. if im blowing this out of proportion, then i apologize. -joep
Mar 28, 2008 05:16 pm I wasn't being sarcastic, nor do I have an attitude or ego.
I was being sincere, and I am glad you found a good resolution.
I'm not sure where you got sarcasm from my post. It was pretty clear and concise. I'm assuming it's just an 'internet' misunderstanding, and no harm done.
Again, I am glad you got this worked out without having to send it back, or having something more go wrong.
Mar 28, 2008 06:05 pm thank you. i am very sorry. i misunderstood your intentions. i dont want you guys to think i dont appreciate your help. -joep
Mar 28, 2008 06:26 pm Nah, PJK is one of our top contributors around here. He's not one to respond with bad intentions, I can vouch for that.
Anyways, glad you got your problem sorted out and you're back in the saddle!
Just out of curiosity...does JoeP stand for Joe Pop?
Mar 28, 2008 06:39 pm nope..joe powers. sorry about the misunderstanding. its hard to figure out where someone is coming from sometimes when you cant hear the inflection of their voice. the last thing i want to do is stir everyone up. i am asking for help after all. on a side note. this mic sounds amazing. regardless of any problems im having with it( these things happen)i am very impressed with the tone quality. i was skeptical at first considering the price. i definately reccomend it. thanks again- joep
