I have read references from various sources referring to a Nagra III parts list. One that was included with the machine at one time. Does anyone know where / if such a list exists? I have found the American written owners manual, the instructions manuals 1963&1967, and the German service manual, which i am in the process of translating to English. I don’t think this parts list was a complete list with exploded views, but rather a text list of items such as pinch roller and belts. I own two N3s and wish to restore them as much as possible. It looks like no one is servicing units anymore, and i have a desire to create a manual closer to a “proper” one. I see various par…

I have recently upgraded my A10-RX to a new A20-RX. The idea is to move from the crowded UHF band to the 1.3 GHz band and to reduce the lenght of the antenna on the A20-mini transmitters. As I was searching technical informations about the effects of obstacles, and especially human body, on the transmission at higher frequencies, I found this very interesting study: https://www.bakom.admin.ch/bakom/en/homepage/frequencies-and-antennas/facts-and-figures/the-effect-of-the-human-body-on-wireless-microphone-transmission.html If I understand well, if the body is an absorber in the UHF band, it acts more like a reflector at higher frequencies. …

OK everyone. I'm off work and I have nothing to do but to read this board. And there's an epidemic of "What frequencies to use in......." -threads so I figured; why not make a Google Document Spreadsheet that ilsts all of these "OK" frequencies to use in different countries? We are legion on here, from all over the world so acquiring the info from locals wouldn't be that hard. Let's give it a try at least. This is the link for it. I contributed with Sweden. https://docs.google.com/a/tjockishjartafilm.se/spreadsheet/ccc?key=0AgnGQulSs_YrdFAwZGZ2LWVjRkRuY0owOEtHcHZqclE#gid=0 Anyone can edit or add information. You don't need a google account to edit If…

Hello All, Need some assistance if you can. I've got the SD633 and I'm trying to record Wav Poly on CF and MP3 on the SD card. I've updated to V4.61. The mixer is not allowing me to record MP3's. I've tried new cards of various sizes and I'm not recording in F mode. I've formatted the cards and I'm at 48K also. Is anyone else experiencing this? Any solutions would be helpful. Thanks, Russ

Hello, I'm new here and to be honest I don't know exactly where my topic belongs. I have had a Nagra III for 3 years (was my dream to have one). Now a week ago the belts started to give problems and I ordered new ones which will arrive next week. At the same time another error has crept in that I just can't find. When I record via microphone, the recording is crystal clear, but when I record via the two line inputs, the recording is simply muffled. Well, let's make it short: I'm looking for a service manual that says how to tune the Nagra (to a specific band for example LPR35 or LPR90). And a manual that says ho…

It's a longer story than needs to post here, but bottom line is : I need to fabricate a cable that brings battery power into the USB-C power port on this new mixer. Q : does anyone know the acceptable range of DC input voltages? The only power arrangement I can fabricate here, while waiting on shipments, will put aprox 14.4 volts into the port, way higher than the 5 V DC that comes with the wall power supply. (as everyone probably knows, the mixer/recorder will give aprox 60 mins run time with the standard 4xAA power module). Standing by with cable cutters and soldering iron! Grant.

Has anyone determined which wireless frequencies are most/least likely to suffer from occupancy sensor interference? The Leviton sensors operate at 5.8 GHz but I have run into what sounds like intermodulation problems in UHF.

I have just read this very clear paper on SD website about the 32 bit float resolution, and... I am blown away. 1528 dB of dynamic range, a headroom of 770 dBFS ABOVE our standard 0dBFS !! I understand now why the MixPre series is so popular amongst sound designers. https://www.sounddevices.com/32-bit-float-files-explained/ But now comes to mind an obsessive question: if gear designers like SD and more are capable of creating machines able to record files in 32bit float resolution, why have they not implemented it in their pro range recorders (like the 8 series for SD) ???!? Anyone capable to clear the mystery for me? Thanks Fred PS: I …

Hi , I've found this website and start read as much as I can!! There are professional users here and you help is really precious. I bought a Nagra 3 recently ( I was looking for it from many years..). It is nearly perfect for what concern the body, it looks like new, this is incredible for a 60 years old piece... and inside seems to be never repaired. All the Red paint is in place. New batteries are now inside. The motor run as it should! 4 speeds Rewind is ok, fast forward too. It plays but the sound is not so loud from the central speaker ... I tried to record putting a bass…

I planned on using an Ambient UMP-2 with a Lectro SMWB for boom. The setup basically works, but there is a whistling noise when using the SMWB. I guess it is neither the cable nor the power supply as I tested both with an older SMa, and there is no hiss. The noise is present on all 3 of my SMWBs. Did someone here encounter this or knows a workaround?

Well, the title says it all. I'll need some XLR cable length that should also serve on SuperCMITs. Maybe 30m max, so it's probably not very relevant, but I thought, I'd ask.

I’m recording a college marching band inside an arena. Should I be worried that it will over power my Scheops CMU6 with MK4 cardiold capsule? Would a dynamic mic work better? I’m concerned about echo too. I’m also wondering if a sanken lav on a drummer would get me crisp drums. Any suggestions appreciated.

I've bought what is marketed as pair of single lyre (19/25) (with modular adaptor & screws) in the 3 shore/stiffness variants (62/72/82) to use them in my Cyclone or an INV-7. For simplicity I'll only refer to 62 Shore variant here. Mine has product code 042255. There is a similar product, with the code 042250 marketed as pair of single lyre (19/25) (with premodular adaptor & screws). Rycote also offers a Cyclone Pair of Universal Lyre with the product code 042270. The lyres that came with my Cyclone and my INV-7 look exactly the same as those I just ordered (just without the adaptor). What are the differences between modular and pr…

Hey All, Apologies if this has been covered elsewhere, I could only find a couple posts and they seemed about 15 years old! I've been recording in 48k 16bit as standard for film/tv stuff, but I'm just wondering if this is still the industry standard, or if I should be recording at 24bit? I'm not asking which is technically 'better', as we all know 24bit is the winner, I'm asking what bit depth do you record in? And what is the expected bit depth these days? Thank you all you lovely people!

one of my 4.2's was running about 20ips , irrespective of speed switch. no , it was not in f fwd.fault traced to poor gold split connections to the speed control board at rear.. unsrew the 2 screws securing the 2 green plugs and gently, with a jewellers screwdriver, prise each split gold pin , slightly wider, to ensure a better tight fit. this cured the problem.

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…

Hi, so, lavs (and microdot adaptors) with a 3.5mm locking connector are usually specified for Sony (UWP-, UTX series) or Sennheiser G2, G3, G4. The latter being widely used by other manufacturers, e.g. Deity, Tentacle and lots more When I look for line in cables, they are sometimes advertised as compatible for both worlds. What are the differences in these inputs? I have a show coming up, where I'd like to feed some UTX-B3 with either my Sennheiser terminated lavs or the HP output of my Track Es (non US).

I am about to be working on a project featuring some trainers doing high intensity workouts and the producers what to achieve the most even sound possible. We have done some of these in the past and we would run one lav and a boom, but due to the quick movement, changing positions, the trainers head pointing in different directions, the lav being covered or pressed into the floor for certain positions, the lav track is not always reliable. When they use the boom to fill in the gaps the sound is quite different and they are trying to figure out a way to get a more even sound throughout. For some stuff this round we will be using a countryman h6 headset, and this will el…

I need some help/advice regarding my Nagra III. I made a DIY power supply from a wall wart (12VDC @ 1A) using a 6 pin DIN and pins 2 and 5 on the accessory connector. Positive is earth/ground. Works almost perfect except for rewind. I've read the manual and other relevant posts here and elsewhere but can't figure this out. Again, playback, record, line in/out and the XLR all work as they should. I have the function selector switch set to EXT and when I turn it to either playback option and turn the tape transport control knob to the 'ON' position it plays no issue. However when I turn the On/Off knob to the left to disengag…

Hello, I've searched this website but haven't found a solution to my issue. Sending 23.98 fps LTC timecode to a Pulse from SD633. The Pulse is connected to the AtomosX via RF signal. As you can see in the photos, all the units are synced perfectly. When I sync the video and audio in post it's off by 4 frames consistently throughout. I was wondering if there was a solution to this where it could be perfectly in sync when matched in post. Thanks!
