  1. Yep. Common ground. no issues here using an old COS11 with the recorder set to 12v phantom for the ext mic. (I believe I left the mic - pin floating, but am not near my recorders to check)

    Poor RF Range

    assuming your system is working fine, its either something where you are working that is messing things up, but my guess would be to think about your receive antenna placement. are they close to the set and above head height? i stopped mounting the receive antennas on my cart a few rebuilds ago to give me more options of where i could set myself up to be out the way and still be able to keep my antennas close to where they need to be.
  3. in the take list, select the file with the A at the end, scroll down to RENAME, and you can delete the A there.
  4. all the ones I know of are UHF. Lectro, Audio / SD, Zaxcom, Shure, Sony. is there a 2.4GHz system that comes even close to the quality of any of these systems?
  5. i would expect to join shield and pin 1. if the 12v is using the black ground wire, that should go to pin 1 as well.
  6. how much power does your setup draw? if your charger is only rated to 3A, you may be asking too much of it to charge your battery and power your rig.
  7. nice work. it may be worth also having the pin outs for the non standard connectors, like the 6 pin Lemo for the Mini LF, as well as the part number of the connector, so its all in one place.
  8. i would guess that if it has an antenna connection on it, it is intended to be used.
  9. right. and? why is that way too much?
  10. indeed, and if you are using the same radio mic system for all your incoming channels, then it makes no difference as nothing is offset. and most top end recorders have input delay to compensate for this kind of thing.
  11. why is it way too much? zaxcom and lectrosonics have similar latency, and i havent seen any complaints about their delay times.
  12. as you say, the ground wire to the case isnt necessary. but it would still be sensible to connect the thread of the SMA to the case. just file away a little of the case where the threads will make contact with it, and at the top of the case where the bolt will tighten up. as long as when you test with a continuity checker there is no connection between the centre of the SMA and the shell, you should be ok. i would also suggest a higher wattage soldering iron, as it doesnt look like youve properly melted the solder, but have held the iron on too long, and melted the insulation of the yellow jumper cable. and it may also be, that if the wire came away from the pin of the SMA, and wasnt ripped off (you can still see the tinned end) that it may not have been properly soldered to the SMA which could have affected your signal. good luck for attempt 2. im sure you'll nail it.
  13. i just measured them and the barrels are 12mm long. ive never been happy with the power connectors that you were looking for initially. the cable clamp never feels particularly effective, or cuts into the outer coat of the wire, which is never good for a power connection. if its for a power supply, an option might be to fit a 4 pin XLR to the power supply, then make a 4 pin XLR to the cable i linked to.
  14. i use these https://cpc.farnell.com/pro-elec/jr8306a-2m/lead-dc-extension-2-1mmr-a-2m/dp/PW01940?ost=pw01940 cut the female end off at the length of your choice and put your chosen connector on.
  15. i only use 4061 and 6061 mics with my Audio Ltd transmitters. which have proven to be a very good range for level. coping well with loud shouts. when i first got the 1010s, i also got a load of DPA slims with the same sensitivity as the 4060, and they were waaaay to hot. i had to have the gain at 0-1 (the 1010 had a gain range of 0-9 i think) and i think you would have the same issue with the 4060 and 6060. i have done some jobs with other peoples kit where they are using wisy tx with 4061, and that seems to work very well as well. also handling loud shouts.
  16. i predict it will come. though not confident enough to predict a timeline. but.. as SD have one 32bit transmitter available, and i would guess an inevitable 32bit version of the A10 will come at some point, and i believe that SD have said that the 8 series hardware is capable of 32bit. as well as Dante being able to support 32bit, i am hoping there will be a full 32bit system from them in the not too distant future. though a follow up question would be, how would a 32bit post production workflow work? are any of the edit systems capable of dealing with 32bit files? and as you wouldnt need to adjust the gain of the ISOs, how will post easily get enough level for the edit? if there is to be a convert to 24bit step (like i have the option to do with my A20 tx recordings) how sure can we ever be that someone wont screw it up down the line and blame us? or will we have to spend an hour or so at the end of the day to convert the 32bit files to 24bit. though an post record auto convert / proxy file kind of thing would be pretty cool. or even being able to record 32bit files to the main hard drive, and 24bit to the SD cards (thinking of SD products here - zaxcom with its primary / secondary disk setup seems like it could easily be adapted for that) i think there is a large element of build it and they will come. but given how wary post can be of new edit system software updates, it may take a bit of time before we are doing everything 32bit throughout.
  17. are you able to get a hold of another battery and battery shoe? i would guess that there is a connection not being made with one or both of the data pins between the battery and the BG DU box. and (apologies for the patronising suggestion) but it would be worth trying the email again, but make sure you type it correctly, as the contact info on the site doesnt have a mailto link for the email. though i may just be projecting my poor typing on you. good luck
  18. if it's not constant, then it may not be digital rf. are you able to test without the A10s? or at least recreate the situation where you get your white noise whilst talking only?
  19. i dont use negative gain on my LPDAs, though often, i only have the gain set at 6dB whilst my antenna cables have about 10dB of loss. its always a good idea to not have any transmitters close to your receivers, but you arent wrong that digital radios seem to be more sensitive to it. if you are having noise issues with your SSMs, it may be a shielding issue you have rather than an antenna gain issues. in what situation do you get the noise issues? and what specifically is the noise? an increase in white noise could be digital rf. splats and pops could be frequency related, or de-sensing.
  20. No. I haven’t because the situation hasn’t come up. maybe next time I am doing some car scenes and I need the plant mics to go all day I might. but I doubt I’ll be needing to / able to use a power bank in a situation where I have the transmitter on an actor.
  21. i only use the app to turn them off. otherwise id have to keep getting to the transmitter, and that wuoldnt go down well with anyone wearing it. yes. i have forgotten to turn them back on. of course. but not often. though often, I'll leave the transmitters on, and change the batteries sooner. when i did some runtime tests to see how different batteries compared, i got between 3:50 and 4 hours from the sonys. none of the other batteries i tried got past 3:30. lithium AAs will last longer, but i have no intention of using disposable batteries if at all possible. but battery life has been fine for what i need. if you need longer runtimes, wait until the updated A10 which will inevitably come (i have no information on this, but it seems obvious to me that it will come) i havent done any range tests to compare the A10 and A20 or different output powers. when i first got the A20 i used them at 10mw, and range was what i would have expected to have been getting from the A10s. the difference in range between 10 and 20mw i would expect to be a few metres. more power is often not the answer. good antennas, and getting them closer will work better. assuming you are able to work like that.
  22. ive had my A20 since as soon as they were shipping. range at 10mw (normal) has been about the same as my A10 at 20mw (med) according to the manual, there isnt a significant change in run time between 10 and 20mw on the A20. 1mw supposedly has longer run time, but who is going to set their tx to 1mw? get the Sony BX1. i tried a few other equivalent batteries, some claiming higher capacities, and none of them got within half an hour of the Sonys. i have no intention of testing with AAA batteries. tx power is less important than antennas. get a good rf distro too, preferably with some filtering, especially if you are using in a bag with IEM tx. i use an audio wireless DADM 226-DT. if you are working on dramas, you can make the batteries last until lunch, as you'll have opportunity to power down the transmitters in between setups. otherwise expect about 4 hours with the Sony batteries. have the gain controlled at the receiver is fantastic. as is the option to record in 32bit. another nice feature is that you can name the tx via the app, and the name appears at the receiver. i am very happy with mine. costume dept love them too.
  23. yeah. understood. my guess is that the AES42 cone had an issue then.
