Looking for some advice so I can plug a mic to any line level only input; there are different settings out there.... Using 10kOhm & 100Ohm resistors seems to be one of the most common but I am not shure if it is the right choice for me Any help? Cheers!

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.

Good day my fellow sound peeps. Just a question.... I usually use the NP-F970 lithium batteries on my SRb receiver and it lasts a few days. Bought a NP-F550 today and just want to know what the average hours you guys get out of it?Or should I rather ask,at what voltage does the SRb switches off,if the battery runs flat? Thank you in advance

So I recently bought a second hand 416T and have noticed it seems to have a more self noise than I expected as well as not having as much gain as I expected. Not knowing if this is just a common 416 sound I recently got to compare it to another 416T and it is noticeably different. I pulled the capsules out and the 416T I bought second hand has a KS16 cap and the other one has a KS15. I am now thinking that my mic has had a replacement capsule put in but wanted to know if the KS16 cap is 48v? Just trying not to fry any of the components. James

Hello, If using a headphone monitor with a XLR pass-through like the Rolls PM55P, does it matter if I am using cables with a different brand, spec? If not, then in which case using different cables can become a problem? Until now I have only used one cable from source to equipment, unless going through mixers or preamps. Thanks.
