We all have been dealing with Time Code since it was introduced. Why is it still so expensive and hard to make work. Shouldn’t there be a single mass manufactured chip that has all Time Code functions built into it, that can be used in all devices? I had a Zaxcom Fusion that when a IFB 100 transmitter was plugged into the TC on the Fusion, it froze the whole machine. When the Red camera first came along it took several years to get the TC bugs worked out. (There still may be ongoing problems). On the show I’m on now, when the DIT’s Time Code Generator gets hot we loose code. He’s on the latest, greatest Codec system. I know that every one of you ha…

Does anyone has problems with delay...and I don't mean the FX version. I'm wondering why on the Sound Devices 744T anyone would need to necessarily delay the inputs. Of course there could be the very rare occurrence. But by the time you even notice a delay wreaking havoc on something isn't it too late? I'm assuming delay in the process does occasionally occur...but at what points have you found it to interfere. I can only imagine how long correcting a delay problem onset a run and gun style deal could take..."waiting on sound"

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

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

<<Question: I need to setup multiple receiver antennas in four separate studios as well as outdoor antennas for "man in the street" interviews. I want to have eight receivers in a central equipment rack to keep my life simple and I want to combine the remote antennas into as few coaxial cables as possible to save on cable costs and installation. Can I do all this with antenna combiners, splitters and amplifiers?>> We get questions like this about once a month at Lectrosonics. Combining receiving antennas from multiple locations is not trivial. Most of the multiple antenna systems are "saved" by the fact that the distances from talent transmitter to the re…

I have a Nagra IV-S machine which I used to transfer quite a few 2 track tapes to digital. However, the utility of the machine as a transfer and home audio deck would be magnified a thousand fold if I was able to play 1/4 track tapes on it, of which I have A LOT, as well as 2 track. As a safe transport for old delicate tapes it has no equal. I was thinking that maybe a 1/4 playback head could be installed where the pilotone head is, and could be switched in and out of the playback amp. Has anyone ever heard of such a conversion? Has anyone here ever converted a Nagra into a 1/4 track machine? Or know anyone who could do such a thing? Has anyone here ever SEEN a 1/4 tr…

I did some simple searches on the site and could not find... What is the original definition of ADR? I've always thought it was down the lines of (pun unintentional) Audio Dialogue Replacement, or Recording. But I just finished watching our fearless governator in the orig TERMINATOR and there was a credit for 'Additional Dialogue' by William Wisher, jr. Is the AD for ADR? Up too late for any goodness, Doug

Hi all, Pretty new to field sound. Ive recently been having issues with scanning for clear freq's. i have 4 lectrosonic 411a's. maybe im doing it wrong? my way: Turn on all receivers and transmitters. let sit for a couple seconds. then, turn off all transmitters. Scan with all 4 receivers ( blocks 19,20,(2)21's ) at the same time. find the clearest location on each rx and tweak on all matching tx's. everything is fine until i place them on the talent. It seems like i cant be any more than 10 feet away from all 4 without losing full signal. any suggestions would be great. thanks

Hey Everyone, I'm new to using "Wingman" with my Sound Devices 664, and I'm experiencing some problems that even Sound Devices can't figure out, So I thought to turn to you and see if any of you have experienced some of these problems, and or, been able to fix them. I'm running version 4.01 on my 664 and loaded the Wingman app on my ipad mini and my iphone. With an approved Sandisc SD and CF cards in the machine, and the app up and running, I can put the 664 into record, but the app disconnects after about 2 sec. and the 664 will still be running in record. I have to manually stop the recorder. I can't re-start the app with out completely re-booting the app. I …

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, …

My apologies if this is a silly question or has been asked and answered before. I made a cursory search of the archives and did not find anything on-topic. I currently own a pair of Sanken COS-11D mics, wired with locking 1/8-inch mini plugs for Sennheiser G3 wireless packs. I will soon be adding a pair of new packs to my kit and am looking at at an Lectronics L-series combo. That acquisition will exhaust my equipment budget for a few months. Consequently, I would rather not have to buy new COS-11Ds simply because of the change in connector type (from 1/8-inch to TA5F). I intend to keep my G3s, and ideally, would like to have the flexibility be able to use the COS-11D…

Hi all i still dont know this "block stuff" i do however found out that one sound guy from holland who does a lot off big movie's here in holland sold his audio ltd 2040's since i use those myself i wrote him why? did he not like them anymore? turns out he sold them because they where in the 800 Mhz (our nabour country germany uses the 800 for digital tv)range and he now has the same radio's but in the 600 range. he also told me this 600 mhz range would also improve his distance because of how fysics works anybody feels like explaining why 600 mhz is more range then 800 in noob terms cheers martijn wonder wh…

I've spoken with a few people and read numerous posts where this distinction is not made. I have a loose understanding of it and would appreciate those more knowledgeable chiming in to clarify. I've tried finding this in the ARRL handbook but am not sure what search words to look for in the index. From my understanding, RF gain attributed to an antenna type such as a helical(+14db) or LPDA(+4-6db) is totally different from gain needed to get back to zero on a receiver from couplers or long cable runs using a low noise amplifier(LNA). The antenna gain is similar to microphone pickup patterns and their "reach". A helical antenna radiates a field that is cone shaped( I th…

Can a BWF, with Time Code be treated just like a Wave file without Time Code? Yes it can. But, if a BWF file is created with the wrong Time Code can it still be synced to a picture file in an editing program like FInal Cut? Such as ignoring the Time Code and just syncing manually to the Slate clap. Does the Time Code frame rate effect the actual “clocking” or “speed” of the recording making it impossible to match to a picture recorded with a different Time Code? Can an audio track be re-striped with new Time Code? T h a n k s for y o u r help.

Hi Guys, I had a pretty bad sound issue today and as I am still learning the ropes, I wasn't able to figure it out on set. It happened only at one of my two recording sessions today. I could use any input to get to the bottom of this so I don't repeat it ever again. I completed my first field recording session with no problems. Then when helping a couple friends on an unpaid pickup shoot after, all hell broke loose and my audio is largely un-usable. This is what happened: We were recording in a relatively noisy small restaurant. By noisy I mean that there were loud variables we could not turn off (commercial fridges, loud oven going in the nearby kitch…

A friend of mine is trying to make a .WAV file in FCP with time code for a music video-type application. He sent me a file which played on my MAC but not on my 744T. The 744T sees the file exists on the CF card, including the .wav extension, but says it is an "unrecognizable file format". I called SD, and they are looking into it. Anyone have any suggestions?

TRANSMITTER -- RF INTERFERENCE IN AUDIO 1. Audio cables have to be good (best are Canare 4E6S). Solder joints cannot be cold or partially cold. Shells of XLR connector may not be grounded. The Mixer has to have a good RF resistant input. The cable sends some RF to the following electronics and if they just rectify the RF you will hear it of course. Cooper mixers, with Jensen Trafos are good, so is Soundevices with the Swedish ones they use. Cheap boards are trouble. Some “digitalâ€� boards have inputs that go much too high in freq (excessive bandwidth) and will rectify RF. 2. Some older Schoeps CMC electronics are more sensitive than others – test which seria…

I have a question about the Aaton Cantar X2, I know a lot of mixers use it so figured would be a good place to ask questions, I have been using the Cantar for a couple months now, and love it. Its a great machine, but very complicated to use. I know its probably not the best recorder to first start out with but I like a challenge. My question is, the mixer faders on the top of the Cantar, do I have to assign the tracks or mics to those faders? Or am I just crazy and they are there for a different reason? And yes I have read the manual but translated from french to english it makes 0 sense. I had to get a friend of mine that speaks french to read the french version…

Hey all, I've searched all the usual suspects. Does anyone make a 1ru (or any rackmount size) 4-8 channel LINE LEVEL splitter with XLR ins and outs? I want it for redundancy recording to a second recorder on the cart. The closest I've found is either mic level only or with special phoenix connectors for the outputs. Best, Ben

Hey Guys, I have been using my 552 on a few jobs recently and listening back to a few files a crazy loud noise, resembling radio interference cuts in for a few seconds and nearly deafens me. It's not there monitoring in real recording time but is there when I listen back. Which is terrible news as I can't rely on it for work now. It's nothing to do with radios and I'm only booming and it still happens.. Anybody had a similar experience? I don't think it's a corrupt SD Card as its happened with two cards now. Could it be A faulty mixer / Wav writer? I'll try and post an example later..

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…
