Hello, Hope everyone here is well, I continue to follow and enjoy the Nagra Stories Thread and wish I could enjoy using my machine which is in for repair. I am writing to ask if anyone could assist me with a copy of the Harvey Warnke flow charts, and diagrams. I have the written manual available online but can't find any technical circuitry diagrams. My X4S had the modification installed in 1995 at Audio Services Corporation. I would be most grateful for any help. Thank you MarkC

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 fellas, I discovered the phenomenon is,first of all,I use SD633, Zaxcom RX200 and Trx743stereo, when I switched the SD633 and RX200 from digital to analogue, then two channels(CH1&CH2) output became one channel output(only CH1), and cable is fine，anybody know what going on?

Hey there, I know it is not a great idea in theory to run a digital AES signal through an analog cable, but wondering what real world experiences people have when running for short lengths. I have a specific cable I like to use for all of my bag cables and it would just be going out of my receiver to the input of my mixer, so maximum 1ft. Thanks!

Had a shoot in a building that may or may not have had an FM radio station broadcasting from it in the Mid-Wilshire district of Los Angeles. Multiple frequency scans with my Wisycom MCR42S receivers with the latest firmware produced many clear frequencies with very low noise floors. Upon dialing up the transmitters (MTP40S with latest firmware), the gain level on the transmitter showed that the lav mic cable was acting like an antenna and picking up all kinds of stray RF. Here's a photo of the transmitter gain level in a silent room with a DPA 4061. Tried a B3 and COS-11 and got the same results. At the mixer, it sounded like the signal was gating (compander pumping?) and…

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…

Dropped off my Schoeps CMIT 5U at LSC today for service. Had used it recently with a Roland R-44 (no mixer in this case), and about half way thru a simple one-hour long recording, the mic GRADUALLY started to produce a low-level crackle. Had hoped it was just a bad R-44, but the mic performed the same on another recorder when used. Unfortunately, LSC confirmed it was the mic. Given the mic was performing fine early in the same recording, and gradually got worse, I feel like I'm going out on a short limb to assume the R-44 phantom power damaged the mic? Has anyone else experienced this sort of damage? I couldn't find anything regarding the R-44 damaging a mic. …

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 …

Have just come across an old Soundcraft LM1 mixer that I'd like to dust down and get working properly again. If anyone is familiar with this mixer i'd like to know how to adjust the 1khz tone generator level so it hits 4ppm/0dbu when the master L-R is up to 0. At the moment tone is lining up between 4.5-6PPM when I'm adjusting the needle sensitivity with a tweaker (doesn't go any lower). Thanks in advance!

I'm a recording engineer based in Boston. About a month ago I some tests measuring and comparing the relative sensitivities for various wireless mic heads using a Lectrosonics HHA transmitter, and a variety of compatible capsules(heads). I've attached a write-up of what we learned-some things many of you may be well aware of. It was very interesting to see what capsules were most sensitive. Sensitivity Report.pdf

On my Nomad I want to have 1-8 AES, analog 5&6 and Zaxnet ON. According to the manual I should use setup #13. But with my Nomad (running 7.77) it is missing AES1&2. Only setup with AES 1-8 ON on MY Nomad is #7. But this would be without Zaxnet and no analog IN. Is it my slightly old software? Or just not possible?? Matthias

Hello all, I have got a question specifically for Zaxcom NeverClip users. In transmitters how well does this really work? I mean really, honestly. I am not evaluating different system, asking which one should I get. I have an unusual shoot coming up, where there will be an attack dog on set almost all the time. This can erupt barking without any warning and get very loud from one moment to the next. Even if I can bring down the gain on my isos just in time, I won't be able to change the transmitters settings in time - even with Zaxnet. Thus hitting the limiter/compressor. If I set tx gain really low all the time, I'll lose S/N on quieter …

Files weren't copied off the Zoom H6 and the owner had already managed to format the unit. Fortunately as it turns out the owner's not too tech savvy so he used disk utility to format the 8gb lexar (premium series) SD card, and hadn't recorded anything on it. I have the card, I did some recovery and managed to recover the Wav files. Problem is, the files are broken. I watched and read through mutliple tutorials and I couldn't manage to un-corrupt the files but I was left with the impression that it could be done. I would love to know definitely if these files are 100% recoverable, then I'd know how to proceed with the client. I uploaded th…

Hey everyone, This is my first post on this forum so hopefully this is the right place to post this. If not, let me know. I'm excited to have found this online community and I've already learned a ton from reading through the forum. I'm having a weird issue with my Zaxcom Maxx and RX200 and wondered if anyone had any thoughts on how to resolve the issue. Here's what's going on. Zaxcom Maxx with built in transmitter (Block 23) sending audio and timecode to a brand new RX200. It locks signal and works perfectly as long as the Maxx is being powered by the power supply or internal AA batteries but as soon as I plug in an external battery distribu…

From what I understand, 2 cardiod capsules, back to back, and out of phase, create a figure 8 pattern. If this is correct, which way is front and back of the created figure 8? Looking at the graphs I would think the sides of the cardiods are now front and back of the figure 8, and the two fronts of both cardiods, being out of phase, cancel each other out. Is this correct?

Hi all. I've got a documentary shoot coming up about languages. One scene will be a kitchen table discussion with numerous family members sitting around the table talking, unscripted. Production hasn't given me a number for how many participants will be at the table, and I'm not sure they'll know till shoot day. How would you mic this scenario if lavs weren't an option? I was wondering about hanging two cardioids from the ceiling and recording to separate channels, but feel like that's not necessarily the best option. Looking for recommendations. What say you?

Hello, I did 4 scans on my Wireless Receiver, and the first three make sense. The mixer by itself did not add any significant RF, and the TX by itself added the suspected amount, but when I turn them both on I don't have much to choose from. Any ideas? 1)RX 2)RX+Mixer 3)RX+TX in IFB mode 4)RX+Mixer+TX Thanks, Rodrigo

Hi all, Just curious what typical delay do you setup between boom and lav to avoid phasing. My lectro system creates a 3.6 ms so i delay my (cabled) boom channel +3.6ms on my nomad and pretty much leave it at that. What s your recipe do you play alot with it depending of the situation? Cheers!
