  1. Thanks, I got another USB-C PD Device and now it takes 12V on the Deity. Unfortunately my main goal with this was to use wall power, but have a battery as a backup if wall power fails, but that's not possible as it takes the higher voltage first.
  2. Hello! I just got my Deity SPD1. When powering it with my 65W Magsafe-USB-C it shows it's only getting 9V, which is not enough for my DADM226. I don't know why it is like that, because the Magsafe is supposed to deliver also 12V or more. Which USB-C power supply do you recommend / use with the Deity? And: Is there a way to set USB-C to first priority power? When I attach USB-C and a smart battery simultaniously it first drains the battery and then switches to USB-C. But what I'd like to do on my cart is using USB-C for wall power but having a battery as a backup if wall power is gone. I can't find any settings on the SPD-1 so I assume there's no way to change that priority, right? Thanks!
  3. Hi everybody, I’m thinking about the best antenna for my bag setup: - 888 - AudioWireless DADM226 distribution - Wisycom MCR42 and MPR30 Recievers My dealer sold me 1/2 wave Shure antennas: https://www.bhphotovideo.com/c/product/1434782-REG/shure_ua8_470_636_wideband_antenna_for_front.html But I'm not happy with the lenght, as stick out of my bag pretty much. So I'm thinking about 1/4 wave antennas. The DADM BNC connectors are next so each other so I have to put at least one cable for one antenna to have different positions. I'd also like to mount at least one of the antennas to my ORCA harness at shoulder height to have a higher position. I made some experiments comparing my 1/2 wave to 1/4 wave, 1 mounted to the DADM, 1 at the harness. Also compared the Bowties. In this test I had similar reception with all of these antennas, so I tend to use the 1/4 wave due to the smaller size. But is there anything I'm not thinking of correctly? I read something, that it's not recommended mounting 1/4 wave whips directly to a BNC cable? Thanks!
  4. Probably not the first time this is discussed here - but I'd like to hear your current opinion on this: Which antenna setup would you recommend for analog / hybrid recievers (Wisycom+Lectro), NOT talking about digital (yet): - 2 LPDA or a combination of 1 LPDA and 1 Dipole (also in one setup like the RF Venue (https://www.trewaudio.com/product/rf-venue-diversity-fin-antenna/) or Audio Wireless one) - Active or passive only - or a combination of both 1+1?
  5. Hey Peter, sorry for the very late response... The SL-6 filter did not change anything. I tried all settings also in combination with or without fitlering at the Wisycom LFA antenna. We did another test now after the shoot and of course everything seems fine. On the last day of the last job there was another situation where I had trouble being just in the next room - as soon as cameras and so on entered the set. So I'm quite sure there was something (probably the Teradek) causing my trouble. But still, doesn't feel good like that.
  6. The antennas are above head height (around 2.5m / depending on the ceiling height interior of course). I have extension cables and a tripod to place the antennas closer to set than my cart in case it's neccesary. But I still think it shouldn't be neccesary to do that when my cart is already just around the corner. As it's very hectic job with a somehow chaotic DOP I try to set up the antennas away from the cart only if I have to - to be faster in moving and more flexible. But yes, it seems the way I have to finish this job now (only 4 days left anyway). Thanks for all the ideas and tips.
  7. I'm shooting in Berlin right now. Usually it's OK to find free frequencies here. RX Explorer shows level around -100, -105 on my chosen freqs. Cables are fine. My own sends are around 2 meters away from the antennas. I had time to do another test last weekend at home and also yesterday on set: it worked fine, I had a range of about 40m without any problems. But it's not solved either: the day before, interior, I was fighting again - just in the next room with open doors. It seems to me that as soon as I don't have a direct line of sight anymore and when the actors / TXs (usually mounted on the ankle) are surrounded by the camera and operators the range breaks down extremely - and way too much as it should. I checked the camera and monitors with the RF explorer but couldn't find any extreme RF noise there. Their teradek are in the 5Ghz range. Overall noise in my freq area rises just a tiny bit when I check them with the RF explorer. Also: I'm the second mixer on this show, the other collegue shooting with the same team and camera gear until 2 weeks ago was in the same block (A1) also with lectros and he didn't have any problems.
  8. Thanks for the video. Very good. I knew about overload but not that detailed. But, in the end there are a lot of people out there using passive sharks on short cables into the receiver / SL6. Regarding to that video they would all run at some plus dB into the receiver assuming around +4dB for the antenna but almost no lost due to short cables, correct? so would that mean it’s either better to use longer cables (not really) or only fins that have the option to use negative gain??
  9. What kind of dB are we talking about here? And is there a way to messure / see at what level I'm at? I like the dBμV scale of the Wisys to show me the RF level they're recieving - but they go from 0 to 70dB, different scale. Is there a way to know more exactly the RF level at the Lectro reciever, too? How much dB does each of the 6 bars for the RF indication of the Lectro mean?
  10. Why would you run slithly negative? To prevent overload? I checked every cable now and also switched to whips. It's not better with the whips. It's not that big difference than I expected it though. I also tried another antenna modules instead of the SL6 - the A10 rack and a Audio Wireless DADM226 . Not better, not worse. RF Explorer shows a full level peak close to my transmitter - as does the scan in the RF scan of the SL6 too. Though I'm surprised again how fast the level goes down when I place the transmitter like in working conditions: onto a person, maybe even close to the skin e.g. on the ankle and then I'm in the next room. It's not even 20dB over the noise floor anymore (around -87 or -90dB while noise floor is around -101dB)... But: I'd think the level on the SL6 should be better than on the RF Explorer, as RF Explorers antenna is weaker then the Shark Fin, right? I also compared the Lectro SSM and the Wisy MTP41 (both on 50mW) - not a big difference either....
  11. Yes - it looks similar to my receivers scan - and my chosen freqs are good there too. They are set to the most conservative settings. They are around 2,5m actually - I wrote this topic this morning pretty hectic that's why I wrote 1m... Tried that, didn't change anything. I would prefer 2 sharks too, but I can't change that now. As I have a poor range testing it at home too, I think the walkies are not the main problem - but maybe just increasing it.
  12. I'm working with a rented setup from a colleague which should (and used to) have a fine range - but I have a really poor range and just can't find the solution. He couldn't help me on the phone neither so I try to find more ideas... Setup: - Scorpio - SL6 - 1 Wisycom MCR42, 2 Lectro SCr - short (1m) antenna cable - 1 Wisycom LFA active antenna, gain set to 1dB as I run a short cable only - 1 Wisycom round antenna (ADB2-ADN) I use the filter of the wisycom antenna and have the SL6 filter to wideband. I'm in different blocks (A and C, wisy is wideband anyway). All Compat Modes, Companders, etc. in transmitters and recievers are set correct. All on 50mW. I scan for free frequencies and use FreqFinder to coordinate them. All good. What else could be the problem that I loose signal on a talents transmitter after 10m??? Boom transmission is fine of course. Yes, there are a lot of walkies and video transmission around - but still, the range is far to short and shorter than the system should appear. Thank you guys!
  13. I'm working with a Scorpio for the first time right now and I'm surprised that it still seems to have the same annoying issue I'm used to from my 633: When due to trouble I rename a take wrong so it's got a take name I already had, the recorder adds a A to the file because there can't be 2 files having the same name. (eg. 2-1-T02 and 2-1-T02A). That's good so far and it makes sense of course. But, when I'm changing the take afterwards to the right name or number (or into any name or number), which I haven't recorded yet the A will not disappear. It stays in the filename. Is there still no option to get rid of that? (Besides correcting it in WaveAgent afterwards.)
  14. Sure, that's what I'm thinking, too. I'm still on 4.51. I haven't had the issue yet that: Fixed Rare event where takes disappeared after renaming has been eliminated. But a collegue of mine had and I'm always afraid of it. But I'll upgrade after the upcoming shoot when I have more time to check it out. Thanks!
  15. Hey guys, just saw SD released a new 633 firmware 4.61, already in Jan but I just bumped into it. https://www.sounddevices.com/download/ I am pretty close to a new project so there is no time to try it, so, anyone of you installed it? Working fine? Any problems or anything else why I shouldn't upgrade? Thanks!
