  1. Yes I have. Along with some of the tips also suggested in this thread, the person helping me wrote: Certain transients can cause the crackling/distortion rather easily depending on the source.
  2. That pad, as I understand it, would prevent distortion in the cmc or the preamp input. it isn't the the cmc or the mic preamp that is distorting. This seems to work well for many in a studio setting, but too bulky for a bag after converting to ta3, and they are calibrated to +18dbu, which would not allow me to adjust gain within the 633. http://www.prismsound.com/music_recording/products_subs/overkiller.php no issues on inputs 1-3
  3. What Ive tried now: Schoeps->preamp->Inputs4-6 of 633 =Digital distorted pops What I want to try: Schoeps ->preamp->diode limiter->inputs4-6 of 633
  4. No. I have had similar issues using other preamps, including a mixpre-d, and MP1, both with very effective limiters, which did help but occasionally I would still get distorted pops. I haven't had issues with radio mics, which makes me wonder if the lower frequencies of a boom microphone might cause the distortion. in all cases the audio levels were within safe range. I will build a simple zener diode clamper and see what happens. thanks
  5. +40dBu is for XLR inputs set to line level. ta3 inputs don't have the analog limiter xlr inputs do.
  6. thank you, you are referring to this http://realoldiesradio.com/?p=212 , however I am searching for a circuit that will attenuate the signal once it reaches a certain voltage, depending on which diodes are used. https://www.quora.com/How-do-protection-diodes-work I using the 633 with a 3 channel preamp made by vark audio.
  7. Hello, Can anyone suggest a circuit for a passive limiter, using diodes and resistors. I would like to know if it is possible to suppress audio signal peaks higher than +18dbu. (6.16v?). I am using a mic preamp, with line level out, into a recorder and constantly get digital distortion when there are fast transients like hand claps or even laughter. The recorder has a digital limiter but it does not help. There is a product available in the form of an xlr barrel, but I would like to know if it is a circuit I can put in a small box with ta3f in and out, or something I can add to the preamp out, internally. Thanks, Rodrigo

    Fostex DV824

    I recently bought one of these for $70 and have been using it to record music at home. I saw on a couple of posts mention of software 2.25. The one I bought has 2.21. After cleaning it up it works well, but I am not able to export files to the computer, I believe because of the disc format UDF. Does anyone know if a later software would format the DVDRAM in Fat32, and if it is still available somewhere? Thanks, Rodrigo
  9. thanks. I am asking for a camera man friend that has lots of sennheiser wireless parts, cables and connectors he inherited . I saw lemo 1 pin, battery eliminators, doors, older lav mics. All new. If anyone is curious I am happy to put in touch with him.
  10. would anyone know what this cable is and if would be useful to anyone today?
  11. The editor said that didn't work so it might be an issue with polyfiles. Thanks very much though for your replies.
  12. Does anyone know how to view or keep the names of the audio tracks, within a polyfile, in an editing sequence in Premiere pro? I am on a job where the editor is on location, and when I went to check in, I saw that in the editing sequence all the audio tracks were named a1,a2,a3.....rather than the names I put in the recorder boom 1,boom 2, lav henry.....
  13. I was at the inauguration with a cmit on a pistol grip, mixpre d, the small lectro recorder and wired to camera. We then went to cover the protest where a limousine was eventually lit on fire. That was where I regretted not having a camera hop.
  14. Yes, moving the TX a few yards away does change the results of the scan considerably, but still affects the scan when I turn the mixer on. As I said before, the mixer by it self does not alter the scan, only when the IFB is on. Yes, Block 26, and the TX in IFB mode, by itself scans as expected, (3rd picture) Compatible with what? Its only one frequency. Many Times. My question is, How can an IFB affect the RF coming from the mixer or vice versa? I´ll keep trying different things to find out what is going on, and hope to learn something from this. Thanks
  15. 633, Lectro UM400 in IFB mode and UCR411a, all independently powered for the test. Rx above Mixer in bag, and IFB TX on the side of the bag.
