soundtrane Posted May 16, 2012 Report Share Posted May 16, 2012 Hi, Strangely, 4 of my COS11s (not the D) all 5 years old have lost crispiness and sound "dumb"... All have been taken care of very well, and were last used on a gig about 8 months ago when they sounded fine. I have a brand new pair of COS11s which are also about 4 years old, but never used, stayed in the plastic cover and carton. Checking the older used ones against these clearly showed a pronounced loss of HF and definition. Has anyone else experienced this - maybe age-related deterioration? All four of them! :~( (I am quite sure there is no physical debris on the wire mesh cap.) -vin Quote Link to comment Share on other sites More sharing options...
Toddsound Posted May 16, 2012 Report Share Posted May 16, 2012 I have found that as much as I love these mics, they have a definite life period. After about 4 or 5 years they start to just sound dead. I was not sure if it was all the athletes trying to rip the mics off before I could get to them or what was causing it? Still my favorite mic for size and sound when hidden under clothes. I have just accepted that they are only good for their time and then they need to retire.

Whit Norris Posted May 16, 2012 Report Share Posted May 16, 2012 Vin, I have discovered the same over the years with the COS-11's. Between sweat from actors and a lot of use they seem to have a limited life of a few years.. I would say 3 to 5 years by my count before they start sounding "dumb" Whit Quote Link to comment Share on other sites More sharing options...
soundtrane Posted May 16, 2012 Author Report Share Posted May 16, 2012 Todd, Whit my friend, thanks for this. Oh man, dilema - should i spend 400$ each (used to be around 200$ 4 years ago) on Sankens again or 600$ on DPA 4071's with the microdot adapters? -vin Quote Link to comment Share on other sites More sharing options...
Olle Sjostrom Posted May 16, 2012 Report Share Posted May 16, 2012 Dpa has my vote. I have to admit I've never used a cos11, but DPA has been nothing but solid and sound extremely good. They're bigger and harder to hide, but they won't let you down soundwise, ever. (null) Quote Link to comment Share on other sites More sharing options...
studiomprd Posted May 16, 2012 Report Share Posted May 16, 2012 the permanent charge on Electrit condenser mic's is not really so permanent. Quote Link to comment Share on other sites More sharing options...
LarryF Posted May 16, 2012 Report Share Posted May 16, 2012 That would lower the output, but at all frequencies. Dirt buildup on the diaphragm? Larry F the permanent charge on Electrit condenser mic's is not really so permanent. Quote Link to comment Share on other sites More sharing options...
Marc Wielage Posted May 17, 2012 Report Share Posted May 17, 2012 Every lav I've ever bought gets more "rolled-off" and dull over time, all major brands. I try to go through all of them and weed out the dull ones, but once in awhile, one slips through. Makes me crazy. Dunno if it's dirt, sweat, electret charges, or phases of the moon. As The Senator has said on occasion, "lav mikes are expendables" and have to be replaced on occasion. Quote Link to comment Share on other sites More sharing options...
soundtrane Posted May 17, 2012 Author Report Share Posted May 17, 2012 Ok, i've done it - ordered 4 x 4071 DPAs. With the 3056 Microdot to TA5F adapters. I am hoping they will work well with my LM and UM transmitters... Fingers crossed... -vin Quote Link to comment Share on other sites More sharing options...

Matt McGowin Posted May 17, 2012 Report Share Posted May 17, 2012 Could it maybe have to do with the wiring differences of the old and new lectro wiring methods and/or the different transmitter used? I hope that my cos-11 doesnt go dull after 4 or 5 years. For the amount I paid for it, I do not consider it an expendable. Have you asked your local Sanken dealer about this problem?

Armin Siegwarth Posted May 17, 2012 Report Share Posted May 17, 2012 same experience with rental cos-11 that lost definition in the highs. I got the DPA 4060 (or was it 4061?) for my micron wireless as I was afraid of loosing bass on 4071. Couldn't do a test to compare to 4071 before ordering but I am quite happy with them. Mixes very well with CMIT on boom. Quote Link to comment Share on other sites More sharing options...
LarryF Posted May 17, 2012 Report Share Posted May 17, 2012 We were told you can get them factory wired for Lectro by the head of DPA. There's an 5 suffix or something. Larry F Lectro Is it possible to have them wired for Lectro rather than use the adapters? --- I am here: http://tapatalk.com/map.php?mu24nt Quote Link to comment Share on other sites More sharing options...
soundtrane Posted May 17, 2012 Author Report Share Posted May 17, 2012 I ended up ordering 4063 DPAs instead of the 4071. Now reading what Larry has written, I have asked DPA about this, and if it is true, i would very much like to have my 4063s wired for the Lectros - the universal wiring for servo and non -servo inputs, since I still use some LM and UM transmitters. I'm really hoping DPA responds favourably! -vin Quote Link to comment Share on other sites More sharing options...
ayushahuja Posted May 18, 2012 Report Share Posted May 18, 2012 Hey Vin, Any tips on trying to make the mics sound less dumb? I have a couple of consecutive serial numbered cos11s and one definitely sounds dumb, and it ends up needing almost 8 more steps of gain on the Lectro SM Tx's.

Izen Ears Posted May 19, 2012 Report Share Posted May 19, 2012 I have three DPA 4060s (for plant mics) and one of the usual suspects (I think it was PSS but it may have been Trew) wired all of em with a TA5, they work fantastic as plants. No idea how you guys make those work on bodies... I haven't tried the 4071 yet, but I am interested. I haven't observed this "dumb" sound outta the COS11s, but I've switched almost exclusively to B6s so all ten COS11s usually stay in their case.

Armin Siegwarth Posted May 19, 2012 Report Share Posted May 19, 2012 hi dan, the most reliable to me is to use the DPA concealer http://www.bhphotovideo.com/c/product/545888-REG/DPA_Microphones_DMM0012_DMM0012_Miniature_Concealer_for.html in conjunction with the DPA Double-Sided Tape for Miniature Conceale. But that tape is ridiculous expensive nearly 1 $ per piece. Sticks like hell and leaves nothing back nor on clothes or concealer - even when hot. But I will try other double sided tape like Joey sticky stuff for cheaper solutions. Rycote dots leave glue on concealer and do not stick that well.

soundtrane Posted May 19, 2012 Author Report Share Posted May 19, 2012 Any tips on trying to make the mics sound less dumb? Yes, it's the gain, and a slight tonal difference as well that you may notice if you compensate for the gain on the old lav to compare with a new COS11. decommission. sell. no other way out.

soundtrane Posted May 19, 2012 Author Report Share Posted May 19, 2012 News: DPA will fully support and back its 2 year warranty on any mic EVEN IF you have cut off the microdot and put on any other connector. -------- As for the price of a 4063 with factory-terminated Lectro connector, it is the same as a 4063 with microdot PLUS the 3056 Adapter. Yes, you are paying an additional DPA 70$ (which is the cost of a 3056 adapter) or so for them to sell you a lav with any connector other than the microdot. Strange business practice I must say. -vin Quote Link to comment Share on other sites More sharing options...

Izen Ears Posted May 19, 2012 Report Share Posted May 19, 2012 That's quite interesting! So it's like paying extra to get fewer things; however, if one has no use whatsoever for anything other than a TA5, at least one doesn't have extra crap that can break on each lav... Thanks for the tip about mounting DPAs! I've been meaning to try out a 4071...
