pverrando Posted May 30, 2015 Report Share Posted May 30, 2015 This is an idea I've been nursing along for the past 2 years, and gradually "rolled out" in January. Since then, I've upgraded about 70 CMC4 amplifiers to 48 volt phantom power, not with an adaptor circuit, but a rebuild of each CMC4 to a schematically correct CMC5 preamplifier. Each is thoroughly tested and adjusted to perform as well, and often better than the original T-power configuration. If you own one or more CMC4's that you'd like to use without the need for an external power supply or barrel adaptor, details of the upgrade are available at http://www.cmc4upgrade.com.

Ze Frias Posted May 30, 2015 Report Share Posted May 30, 2015 Pete is a genius. I know a few folks who got his mod done to their CMC4s, and are extremely happy with the results! Quote Link to comment Share on other sites More sharing options...
Sound Grab Posted May 30, 2015 Report Share Posted May 30, 2015 I've had mine done by Pete. Works fantastic. Quote Link to comment Share on other sites More sharing options...
Mario Cardenas Posted May 31, 2015 Report Share Posted May 31, 2015 Pete modified two of my CMC4s, the results are great. Terrific service, excellent communication. Quote Link to comment Share on other sites More sharing options...
bmjord Posted June 2, 2015 Report Share Posted June 2, 2015 I had one upgraded in April. It works and sounds great. Quote Link to comment Share on other sites More sharing options...
pverrando Posted June 10, 2015 Author Report Share Posted June 10, 2015 (edited) Here is a note I've been meaning to address regarding the upgrade, and will be adding to the website. Some Schoeps CMC4, CMC5, and early CMC6 amplifiers are known for RF "noise-up" issues from plug-on transmitters, remote focus transmitters, etc. The CMC4 upgrade, while adding ferrite beads to transistors T2 and T3 where they are found missing, does not specifically resolve all existing RF issues. I have successfully resolved plug-on RF issues on a custom basis. ( lead-in ferrite beads, increased internal shield coverage, filter capacitors). I have not, however, established a "solve-all" process for RF immunity as part of the CMC4 upgrade. If you plan to use a CMC4 upgrade with a Lectro or Zaxcom plug-on transmitter, let's talk about it first! Thanks for the generous endorsements!

Mark Spagnolo Posted June 20, 2015 Report Share Posted June 20, 2015 I just got my CMC 4 back from being upgraded by Pete and I am absolutely thrilled. It works and sounds great. This is a brilliant solution to the T12 issue without using cumbersome adapters. I plan on sending my other one in next opportunity. Quote Link to comment Share on other sites More sharing options...
NYorker Posted June 29, 2015 Report Share Posted June 29, 2015 If only I could get the same conversion service for my Sennheiser T powered 416. I would be oh so happy. Quote Link to comment Share on other sites More sharing options...
osborne456 Posted August 2, 2015 Report Share Posted August 2, 2015 Pete's 12vT to 48v conversions work flawlessly. Quote Link to comment Share on other sites More sharing options...
berniebeaudry Posted August 21, 2015 Report Share Posted August 21, 2015 Just had this done and couldn't be more pleased! Thanks Pete my mic sounds great! Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted August 21, 2015 Report Share Posted August 21, 2015 Just had 6 of them done by Pete, very happy. Waiting for his new Senn 416/816 T>p48 mods! phil p Quote Link to comment Share on other sites More sharing options...
josephboyle Posted July 29, 2016 Report Share Posted July 29, 2016 I know this is a fairly old topic, but I just wanted to add my voice to the choir. Just had my CMC4 done last week and it sounds great. Pete does great work! Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted July 29, 2016 Report Share Posted July 29, 2016 Pete converted my old-guy 416T too! Boffo! Quote Link to comment Share on other sites More sharing options...
tourtelot Posted July 30, 2016 Report Share Posted July 30, 2016 Yep. The man does awesome work. Not only on this conversion stuff but he repaired a CMC5 of mine and it was back to me in a week instead of three months (!) when I send mics back to Germany. Don't get me wrong, Schoeps in Germany sends back a repaired mic, but I think no more repaired than the mic Pete did for me. Just my .02. D.

John Blankenship Posted July 30, 2016 Report Share Posted July 30, 2016 Three CMC4s and a Sennheiser 816. I'm pleased to recommend Pete's work. Quote Link to comment Share on other sites More sharing options...
berniebeaudry Posted July 30, 2016 Report Share Posted July 30, 2016 I bought a used CMC4 and had the mod done by Pete! Great sounding mic and great work! Quote Link to comment Share on other sites More sharing options...
ryanpeds Posted August 8, 2016 Report Share Posted August 8, 2016 I bought a CMC4 with the mod and I recently bought a gvc and for some reason whenever I use the gvc it doesn't work but when I use the gvc with my CMC6 it works just fine. Anyone know why this might be happening? Pete, can this issue be resolved? Quote Link to comment Share on other sites More sharing options...

Philip Perkins Posted October 13 Report Share Posted October 13 I contacted Pete about service for some mics he converted. He said he's not currently doing conversions due to family/health issues. I wish him well and very much hope he can get back to work soon both as a mic tech and as a working production sound mixer. Quote Link to comment Share on other sites More sharing options...
JonG Posted October 14 Report Share Posted October 14 And I’ve been dragging my feet on converting some mics... Quote Link to comment Share on other sites More sharing options...
