Hey all, I've edited this topic as I think people are getting confused and answering the wrong thing. I've gotten early into the preproduction of an upcoming film on which I will be sound recordist. It is a great opportunity to do whatever I can before those rushy production days. One thing I told them to do is wash the wardrobe. This is based on information I acquired here in posts about reducing lavalier clothing noise at jwsoundgroup. They asked me if there were any specifics so I decided to ask you guys directly. I wanted to know if anyone knew anything about the following: -Whether they can be safely washed several times in a row (without drying until t…

I have this old Micron tx 501 with a Sony mic but as the Sony is so big to hide I think I would like to change it to a RODE one as can change the cable with those so I can use it with Micron with its own cable. Now you older professionals might remember how to connect this combination. Tried the same as with Sony and didn´t get it working so I put the Sony back. The Rode cable is a nightmare to solder with bad eyesight at least... As a retired sound guy this is more or less for hobby, but if someone can help I would be very thankfull! Matti

Hi, My general understanding of this phenomenon is that mics equally spaced apart in relation to a sound source, if mixed together, result in a degraded audio signal. For example, here is Audio-Technica's explanation: http://www.audio-technica.com/cms/site/f54c2e7c578b36f7/index.html My questions: 1. If the two mics consist of a lav (1' from actor's mouth) and a directional mic on a boom that moves to 1' (very close miking) would phase cancellation occur? I am assuming it would... 2. If one iso'd such mics, would they also produce cancellation if later mixed or layered in relation to each other? Thanks in advance, Mike

Forgive me if this has already been covered, but could not find in a search. I'm looking to contruct a female xlr > 6 pin lemo for micron cable. Does anybody know how the hot/cold/shield from the starquad xlr female cable terminates onto the 6 pin lemo (for micron-style connectors). I solder xlr cables very frequently but haven't tried soldering lemo connectors before (I gather they can be very fidgety!) but fancy having a go in some down-time. Any tips much appreciated!

Hi Guys, New on here and new enough to location recording I hope you can help me out here. At the weekend i was shooting a scene where the talent was almost whispering and eventually went onto screaming. Just wondering what the best way is to record this. Is it a case of setting low levels to avoid clipping or pull back the boom? Thanks

Does anyone know; if a monitor only has HD/SDI input, will it be able to receive a 3G SDI signal? I may be purchasing a used Marshall dual monitor that has only HD/SDI but most likely it'll be plugged to the output of a teradek bolt receiver. Cheers! pablo

Hello all This is my first topic. Today I left my Soundcraft Signature 12 to the local audio engineer to be modified to 12volt DC power. I plan to run it through my MeON cart power with 12volt DC on 13Amps. I wrote to Soundcraft and ask them for some schematics about board's power rails. They give me just a simple answer like this one - " Yes, as an analogue mixer with USB functionality, it does indeed require +/-17V (approx), 5V (USB) and 48V (phantom power). regards" So a week later I will have some more info and can tell you more about this. Really hope all this will be s…

Hi All! I know it's not usual but I am in a strange situation and searching for a solution. We have a film that has only this sound source, all other original materials got lost during the years... I am searching for a projector sound head or whole projector to digitize this film's sound: That's the best I found about it on the internet: http://www.graumanschinese.org/projection-2.html The whole point of CinemaScope was to give the public that Cinerama feel — without having to make expensive alterations to a theatre. Because of the grain factor, Sponable wanted to use as large a negative as was possible in 35mm, which meant going back to the silent aperture, …

Has anyone tried connecting the BNC output of a Lectrosonics Venue System to the BNC input on a Sound Devices SL-6? I want to share the reception my Venue System receives from my powered shark fins with a 688/SL-6 set up to expand my wireless setup on my cart. The coaxial run between the Venue System to the SL-6 would only be 50cm or so.

I recently bought some secondhand Countryman EWM lavalieres and was hoping to re-terminate them to fit a Sennheiser G3. I received them today and am a little puzzled as to how to do this exactly. There is a huge preamp looking thing on the end which is essentially housed in the XLR. Having only worked with Sennheiser ME2s and DPAs I have never seen this before and am wondering where to take it from here.. Any advice would be great. https://goo.gl/photos/mdJ71CtwY77Zajy27

Hey guys, I'm pretty good at sound, but not so much at soldering. I have a 5 pin lemo to 1/8" TS (TC OUT) cable I got custom made from one of the usual suspects and I was shocked to find that the only thing keeping the cable from coming apart was the solder itself with no strain relief. Is this normal for a Lemo connector? Needless to say it's in 2 pieces now. To make matters worse, I tried to fix it myself and all the pins are now more or less wired together, solder everywhere. So #1) What's the best way to remove the unwanted solder so I can start over? I've watched videos about solder wick (copper braid) and solder suction devices but can't find them in my local har…

I'm going to be installing some video monitors into a rack mount. I'm thinking of placing a 'patch panel' on the other side of the rack. So, I guess I'll need to make up some smaller patch cables that go between the monitor(s), and the patch panel. What is the ohms on the video cables? 50ohms, 75omhs? Does it make a difference? Have you guys made your own BNC to BNC cables? Has anyone done this? Thanks -Richard

633 T Power

I was just curious if anyone else has had this problem or knows what I might be doing wrong. I have a T powered 416 when plugged into the 633 with t power I get no signal yet when I feed it 48v with a 48v/12v adaptor it get signal. Could I be wiring it wrong? The reason I ask is that I seem to be getting a lot of high freq noise and doesn't seem as clean as p48 versions I have used in the past, I was hoping to remove the adaptor from the chain to rule that out and hopefully get my 416t sounding better. Any help is greatly appreciated.
