  1. I don't personally own them, but I have used them a number of times paired with a Shure Axient system when I was hired to work without my gear at META a couple of times last year, and I thought they sounded very well. They were always used exposed, so I don't really have a direct comparison when compared hidden to Sanken or DPA. Visually I thought they looked and felt tough, but also perhaps somewhat "cheaper" than a DPA/Sanken? That doesn't really mean anything though. I think the company looks solid and they make affordable priced mics, and seem tough and sound good. I would not hesitate to use them if I had them on hand.
  2. Thanks for letting everyone know how it turned out! Great to hear SD treated you well.
  3. And how much current does that use? Octopack 1.5A w/ 4 SR (That's max, probably quite a bit less) Scorpio 1.67A w/ Dante & all preamps, no charging 2 x Lectrosonics SRB 240ma (12v) 1 x Lectrosonics T4 200ma Zaxcom QRX200 390 mA (12v) Tablet charging 2A (max) 6A Total Maybe your antenna distro takes a few more milliamp of power... You're not even close to hitting 10A, though.
  4. What kind of equipment is in your sound bag to pull more than 10A? That's quite a large power draw. 10A seems like a high limit for 99% of sound bags.
  5. I agree the PSC is a clean and easy solution. But curious why you consider mini circuits a disaster waiting to happen? What points of failure? Lectrosonics themselves highly recommend them. I've never had any type of issue with them either. PSC doesn't publish intermod figures or real performance measurements for their RF amp, so it's likely not going to be anything super high quality. So while it works in the right situation, it has RF weaknesses. BSRF and Zax and SD's SL2 have overload LEDs that at least show when their high gain, low power amp is being overloaded by your hop TX next to your antennas or when one talent wants to hang out next to you and your filming a scene with other actors across the pond.
  6. To be fair, that's potting compound, and that's a common PCB board covering that 1) seals dust and water 2) is a deterrent against reverse engineering (and hiding the board) 3) provides better thermal conductivity than air. So that's not uncommon, but makes products unrepairable. The soldering is otherwise fine, as far as I can see. I actually do have one of these that I purchased many years ago on a whim, but I now somewhat regret despite the low cost and don't have use for anymore. The Aliexpress copy does technically work as advertised and I have used it a couple of times successfully. I know it sounds so useful to have a small box that could split 8-way, and provide antenna power – but I now strongly think these products, (including the original PSC) just aren't worth it. They have relatively crappy, cheap and noisy RF amps, and are poorly filtered for most of our uses and easily overload/distort and there is no way of visually knowing when the units overload. I think these products are a huge potential for intermod hell, when in difficult RF environments. IMHO, If the point is to have remote-able antennas in a bag setup, it makes so much more sense to purchase some passive mini-circuit splitters. If you're splitting 3 way, the loss is fine and just use some passive antennas. If you're going to 4 and beyond, I would invest money in a quality active antenna like the Lectrosonics ALP690 instead, and this way to you can overcome the loss from the splitters and cable. If the point is to clean up a bag to avoid "antenna farms" and just poking two dipoles out of a bag, I think you are loosing more than gaining.
  7. I saw that too, but is that bad, 10A total? That seems pretty sufficient for a bag or small medium cart. The Remote Audio BDSV4 is specced up to 5V globally. And I couldn't find anything about the Audioroot BG-DU besides a 2.5A per output limit.
  8. Unless I'm misunderstanding something, it's in the manual, no? "10 VDC/2A to 18 VDC/1.2A" So, it would like 10-18VDC, and the current consumption is 2A at 10V and 1.2A at 18V. If you calculate that, that's about 20-22 watts, depending on voltage supplied.
  9. That’s correct! Between the antenna and your distro, and you will need two. There’s about a 1db loss or so, but that’s not worth worrying about.
  10. The Betso Bowties are very wideband, and only have a low pass filter at 700mhz. Their advertised range is 470-700mhz, but they do not filter below 470mhz. You could perhaps try a Lectro SNA600 dipole that has a 100mhz bandwidth or putting an in-line filter ie. PWS IN-LINE BANDPASS FILTER It’s also likely that your PSC distro’s RF amp is overwhelmed and is causing RF distortion/IM products that a filter might mitigate.
  11. I think I would add two things here. A RF distro is a good problem solver, but it can also be a problem adder. And I disagree that a bunch of whips are a RF disaster. What’s wrong with a bunch of whips? They said that they will have other TX in the bag, such a camera hop which will likely be quite close in frequency range to their receiving antenna. In a bag situation - with antennas not remoted -, the likelyhood of overloading a compact, low-current, high gain RF amp increases drastically, especially if using one without an RF overload indicator. The intermod products of a distorting RF amp aren’t exactly great either in a bag. So I think that’s seriously worth keeping in mind. The question was, would you be fine just adding two more SRc receivers with whips to your bag. I don’t see a problem there. Would you be able to get more range out of the system with remoted antennas by using a dipole or sharkfin with an antenna distro? Very likely yes.
  12. Yes, I misunderstood that slightly. They are specific to each combination within each frequency block. “256 pilot tone frequencies are used across each 25.6 MHz block within the tuning range of the system. This alleviates erroneous squelch activity in multichannel systems where a pilot tone signal can appear in the wrong receiver via IM (intermodulation).“ - Per the always excellent manual. This makes a lot of sense and a good system to keep intermod products from messing things up. Larry’s explanation of the 19/470 overlap is great and it makes perfect sense.
  13. Well, hindsight is everything and I'm sure there is some regret at Lectrosonics, because it does cause some confusion in today's wide-band world, but that is the nature of keeping things backwards compatible. They could have fixed this at any time, and broken the backwards compatibility, so I would say – pick your poisons. Regarding the use of block specific pilot tones – it keeps intermod products from unwanted un-squelching on neighboring block receivers. It is generally a good thing, and it does have a reason.
  14. But this isn't newer stuff. You are working with a system (Digital Hybrid Wireless) and method (Frequency Blocks) that was introduced in 2002. Situations like yours are a side-effect of Lectrosonics' pretty incredible backwards compatibility throughout the years. You can use a transmitter from 2002 on the latest receivers from Lectrosonics, like the DSQD and the the DCR822, 20 years later and they sound and work great. That's pretty incredible and part of the reason why many of us like using their products. So the overlap is a side-effect of that, and does not appear to have a solution unless a receiver comes out that can sense and adapt to two different pilot tones. However, when you update to their truly newer stuff, you can. All their D2 digital series do not use pilot tones anymore, and have no 470/19 overlap. So that might be the answer if the overlap is consistently too frustrating to navigate.

  15. Shure looks like a slot style receiver to me, too.
  16. A big and a small tumbleweed, for a digital SMv and a digital SMQv
  17. I did this last year. It took me a lot of research, because I was overseas and couldn’t send in my 633 just for that. The battery is relatively easily replaced, just open the 633 and you’ll see it. Getting the exact part and the exact type of connector took a lot of research. It’s a long time ago so I don’t want to find all the specific specs again, but this was the battery I ordered and used. This is amazon japan but I’m sure you’ll find a fitting battery somewhere online with the same specs and most importantly the specific connector: https://www.amazon.co.jp/gp/aw/d/B01N9SXEYV/ good luck and hope this helps.
  18. They look great, but they're not smaller than the Tentacles. TCX-2: 35 x 59 x 16 mm (33cm2) 45g Tentacle: 34 x 50 x 16 mm (27cm2) 30g
  19. I'll post what I posted on the other thread, for reference, and included the Betso SBOX-1N. Curious to see what Denecke eventually decides to release to stay competitive in the small lockit market. Tig Q28 6.67cm x 5.4cm x 1.27cm (45.74cm2) 53g 0.5ppm 16hrs on 2xAAA US$439 Ambient Tiny Lockit 7.15cm x 5.6cm x 2.0cm (80.1cm2) 118g ~0.01ppm 12hrs on 2xAAA US$891 Betso SBOX-1N 7.5cm x 6.2cm x 2.0cm (93cm2) 134g 0.1ppm ("better than") 60hrs on 2xAA US$490
  20. Just for reference, in case someone was curious. They're two different products and the Ambient can obviously do a bit more (ACN network), but that said, neither can do Gen Lock and they're going after a similar market. Tig Q28 6.67cm x 5.4cm x 1.27cm (45.74cm2) 53g 0.5ppm 16hrs on 2xAAA $439 Ambient Tiny Lockit 7.15cm x 5.6cm x 2.0cm (80.1cm2) 118g ~0.01ppm 12hrs on 2xAAA $891
  21. I'll mirror that. Block 21 is good, and similarly Block 25 was ok.
  22. Nothing. Zero. Nilch. Radio silence.
  23. On my last show, rentals also went trough payroll, they did the same thing. I had a long discussion with them that ended without results. I forgot the exact reason again. It's a new development that started this year, if going trough payroll. I usually don't.
