  1. Looking Into Buying Zaxcom IFB

    Interestingly, I have always been very happy with the range I get with the Zaxnet control commands from my nomad (unamplified, short stubby antenna) to my TRXs. I guess it has to do with the nature of the signal being a short discrete "word" of 1's and 0's rather than a constant transmission. It's not hundreds of meters, but it's good enough most of the time.
  2. Looking Into Buying Zaxcom IFB

    I Agree with everything you said, and I have had a great many days when the ERX system has performed just fine. However, my overall feeling is that the ERX system was a lot of: "I hope this is going to work" instead of "I know this is going to work" that the lectro IFB is giving me. I use a all-zaxcom system for everything else and am very happy with it overall.
  3. Looking Into Buying Zaxcom IFB

    I have used ERXs for timecode + scratch track and IFB for a few years and have recently sold them all. I believe it was a really good idea unfortunately poorly executed. Only my humble opinion but simply put, don't buy them unless you mainly do cart work. The range out of the stock nomad antenna is nothing short of unacceptable with dropouts from 5 meters in some cases. Amplifying the signal is an option and many here have done it successfully but be ready to dive into a world of prosumer/dodgy ebay seller products/custom cabling to make your IFB range acceptable. On the cart it's doable as a fixed setup. In the bag it's just a nightmare. I have swapped to lectro IFBs and after years of sweaty palms everytime I handed a client an ERX, I love them. Range is rock solid just out of a cheap old Lma transmitter I had lying around, unit is built like a tank. Just set and forget. I have 2x RX200 that I use for camera track+timecode and everyone is happy.
  4. cart power opinions

    Hi Tony, I have purchased the PSC Cart Power II last year and am very satisfied with it. It doesn't have an internal battery, which may or may not work depending on your needs. I actually find the lack of internal battery a great thing since I am free to build my own pelican SLA at a very low cost or even use any V-lock or NP1 for emergency power. It also provides redundancy with AC power just like its bigger brother. I am actually surprised not to have heard more about this great little unit. http://professionalsound.com/specs/cartPowerII.htm
  5. Zaxcom Link - Advice for a new recruit

    I have been using Cam link with rx200 for about a year now and would never go back. fully digital from the talent TX all the way to the camera tracks, the flexibility of internal powering and timecode output are a dream come true for both the cam op and I. one quirk so far, make sure to carry an analog Ta5f cable if you're working with Sony F5/F55 as the camera will give you an error message: "AES EBU is not in pro use" if the links are powered before the camera using AES inputs. Even though it is a Sony firmware issue and can be fixed in about 2 seconds by power cycling the rx200, some camera op will get kranky with you. Sent from my SM-G935F using Tapatalk
  6. DPA - Slim

    I have recently received 2 of the Slims to work with my TRXLA2. On the noise issue, I really can't affirm that there is more noise or less dynamic range than the 4063 in the same transmitters. Yes there undeniably is a slight but audible hiss when the levels are pushed, as far as I can tell, just as much as with the 4063. However, in a full digital environment (TRXLA-RX12-AES-Nomad), this hiss could originate from a number of factors and their combination. I am not 100% sold on the concealer tube provided with the DPA slims. Sure, it works and gave me usable results on starchy business shirts but not as good as the old poke-the-mic-behind-the-button technique. It is good when working with button/shirt colors that my mics can't match. The flat form factor makes it very friendly to use with tighter tee-shirts and women's tops. All in all, I'm happy, so are my clients and Zaxcom/DPA couple is still the best wireless sound I've ever heard.

    Long day...?
  8. RG405 coax cable vs. RG174

    Hi Paul, I am using RG174 in the bag with PSC rf multi (zaxcom wireless). It's been working just fine for patch to receivers and very short run to my sna600 antennas. This isn't the one made by PSC (I made my own) I wouldn't use rg174 for any runs longer than a couple feet, fine for patch lengths. Hope that helps.

    That looks amazing. I wonder if this would work with QRX200/100 or only RX12. Can't wait to see it in action.
  10. Bag RF Distro custom cabling

    I have certainly read the same mixed reviews about the Zax + PSC RF multi. The micplexer wasn't an option for me because I use a mix of TRXLA lower blocks and older TRX900 Block 25. I am happy to report that everything is working very well. Originally, I purchased a couple of lectros PF-25 filters as recommended by Glenn from Zaxcom on this board in case I needed to filter the wideband RF down to 1 block to avoid overloading the front end filters of the QRX200. It hasn't been necessary so far. My rig is Lectro SNa dipoles or Zax Bluefins ==> RF Multi ==> QRX200/100 I haven't been able to compare it against a Micplexer since very few soundos in Melbourne use Zaxcom wireless. However, it has definitely been a major improvement from floppy antennas alone and more than enough range for 99% of my work.

  12. Bag RF Distro custom cabling

    Hi Steve, This may not be the answer that you are looking for, but I would recommend making your own RF cabling. All you need is some of these http://au.rs-online.com/web/p/sma-connectors/5463248/ http://au.rs-online.com/web/p/sma-connectors/7123191/ and these: http://au.rs-online.com/web/p/bnc-connectors/5463620/ http://au.rs-online.com/web/p/bnc-connectors/1123457/ I use RG174 for coax cable, it will work just fine for such short runs. You will also need a good crimp tool. Get one with interchangeable dies so that you can use it for different sizes of connectors and cables in the future. Example: http://www.jaycar.com.au/Tools-%26-Soldering/Hand-Tools/Crimpers/Quick-Change-Ratchet-Crimp-Tool/p/TH2000 You will also need a soldering iron with a fine tip to solder the center pin on the right angle sma. RF patch cables are really not that hard to make and it very cost-effective compared to buying them pre-made, not to mention the ability to repair or make new ones on the spot. Anyway, hope that helps. Cheers, David
  13. DPA 4063 DAD3057 Adaptor

    Hi mate, I have started using the DPA4063s with DAD3057 adapters in my Zax TRXLAs and LTs about 2 months ago. I cannot tell you exactly which pin is wired to which. What I can tell you, however, is that I own 6 of them and have not experienced signal/noise, interference or range issues of any kind....and that the resulting sound is hard to beat. Hope that helps. Cheers,
  14. mkh 50 and zaxcom trx 742 problem

    Been using MKH50 with TRX742 at the end of the pole all week. No issues at all. My jump lead is regular Neutrik, wired pin for pin. XR modulation 25 mW. Weird.
  15. Ambient Tiny Lock It Outdoors?

    Hi Michael, I've been using tiny lockits on the back of cameras in all (Australian) weather conditions for a while now and am yet to report any issue what so ever. These things are little tanks. I always keep them in the pouch and they go under the camera rain cover when it rains. Same goes for the Lockit slate, never had an hint of a problem.
