Wow what a cool microphone, I'd like to try it in business, thank you for the beautifully written review

Nice article about Daft Punk's latest album. I hope they really can make a change regarding the loudness wars in the industry with it. I also read Mick Guzausky's interview in S.O.S about how he mixed the record.

Not sure if this album can really be seen as a "Milestone" in the music business though. Sure the production of this album is flawless from the beginning to the end (which is kind of rare on most albums nowadays). But in order to change something regarding the loudness war a lot still needs to change. Luckily Youtube, Apple and Spotify are going in the right direction.

Nice job Gleenbrown. I feel it's pretty well done. I'm loving it!

Hey Tom, yes I believe you are right, the DMR-2000 unthreads for faster spooling.  I don't recall if it reads code while spooling; probably just CTL track.

I was the Creative Department manager at Sony DADC Australia, there for 12 years before I had to step down due to health reasons.  Most of my 1630 stuff comes from there, which is why it's frustrating trying to find this cable; I installed it and it was in situ and working until a couple of years ago when the building sustained water damage and the older mastering rooms were decommissioned. 

I deal with people who still have the odd 1630 (or 501/701 etc; often they don't know the difference).  There's also some record companies etc who still throw the odd request.  As part of our policy to have 'one of everything', I'm trying to nail this in my spare time.

I might try some of the other plants.  Thanks for the idea.  Cheers - Brett.

I agree with the above tests...I know things can get goofy if the interconnects aren't wired correctly when going from balanced to unbalanced gear. Some balanced outputs use different methods than others. I know the Apogee I have needs to have pin 3 tied to ground if feeding unbalanced gear. I'm not sure the Myteks do.

OOPs...Pretty old post...

Sorry...New guy here...

Mikey, thinking about it it could be a tension problem, at higher speed the motors need to turn faster so will need more drive. Do you have a tentelometer? Check tension at stop, then 15, then 30. If the takeup tension is lower at 30 that would point to a problem with the drive circuit on that side. I am going to Auckland next weekend and will check on the Studer there. The capstan card checks out fine here, all values around that output are correct. There is one Frako cap on the power supply on the board, mine metered sort of OK but I changed it anyway. It is 20 volt decoupling so I dont expect it would have been the issue.

Hmm, from your symptoms, I would still say that it is the capstan card that is at fault. I haven't got around to measuring the same parts on the one here yet. Interesting that things improved greatly when you changed the reel bridges. Can you try running the old bridges under load on a d.c. supply? Some of these things will measure fine on a meter, but fail under load, with higher than normal saturation voltages.
Can you revisit the capstan card and see if you are getting right voltages there now?

Hello Nick,
First and foremost, I try as hard as I can to avoid what others are often tempted to do, and what I dislike with a passion: self promotion on an informational forum. Contact me privately for any work-related issues.

Regarding your questions:

"Handling" noise is common on C414EB. The handling noise is due to insufficient damping of the capsule against its frame, against the frame's hard rubber mount on the amp chassis. This kind of noise is in the 50-200 Hz range and hard to tame, given the tiny body of this large-diaphragm mic.

Pattern-and attenuator-switch rumbling and discharge noise, when actuating the switches ,can be tamed to a degree, on this model: AKG used primitive plating on the contact surfaces, which needs to be cleaned and re-lubricated periodically with an anti-oxidization fluid.

It is quite possible that the dirt and dust accumulation on your mic's diaphragms and backplates could be the cause of attenuated top end response: When the dirt load gets high enough, the 6 membrane can no longer follow fast (high frequency) wave lengths.
When a mic sits openly over long periods of time, airborne dust will continually fly to the unprotected capsule form as far as 6 ft. away, due to the electrostatic charge on the backplate (polarization voltage and its residue, even after disconnecting the mic from power). Capsule restoration to factory stock is often possible, provided there is no other diaphragm deterioration (see below).

If your capsule suffers from diaphragm tension loss, there is no remedy, as the diaphragms are glued to the diaphragm rings and cannot be re-tensioned.

Hello Klaus,
Well, I did as you said but I cannot see any evidence of either side being sucked in. There was no indication of that - unless it's REALLY subtle.

I changed patterns and turned the phantom power on and off but saw no effect. I did this under good light and both sides look flat and uniform. I will say, however, that the front looks very dirty. (The mic used to belong to a large, commercial studio and was used quite a lot.) However, when I reassembled the mic, the sound was vastly improved. The front of the mic sounds very good.

There is an exceptional amount of "handling" noise (I don't know if that's common for this model) and very loud sounds when I change the patterns. I tried omni and figure eight. They both appear to be working but the sound in the rear is certainly duller than in the front of the mic. Again, I don't have a clear sense of what is to be expected so the result is difficult to gauge.

I have read very high recommendations of your work. Is it possible for me to have you go through the mic and see what's going on, clean it, correct any loose connections etc.? Can you give me an idea of what a routine cleaning and maintenance would cost? If it is the diaphragm tension, then I can make decisions from there but at the very least, I think it needs to be cleaned and serviced. Are the conditions I described consistent with the loss of diaphragm tension? Do the symptoms of that type of failure occur intermittently? Thanks again for all of your help.

Thank you, Klaus. I will try this and get back to you with the results.
