    URSA mini mount

    Is it very smooth? Does it make any noise with fabric rubbing against it? I tried the hide-a-mics and found that with certain fabrics there was an awful hollow plastic scratching sound. The metal wire concept that the DPA concealer uses seems to work more often than not.

    I think it’s an upgrade part.

    DPA 3mm lav mic

    So I want to know if these will work with Sanken accessories and mounts.
  4. http://www.all-battery.com/9V_li-ion_rechargeable_combos.aspx -500mAH, 8.6 V peak, 7.7 V nominal, 6 V discharged -$5 per piece -6-bay charger. I think I'm going to buy a set of 6 and test them out for Comtek duty. I know there are some folks here that use Tenergy products with good results.

    DIY Dipole antenna!

    And a VNA is what?
  6. If for whatever reason you want to stick with starquad Belden 1804A is a good one and way thinner than the Canare mini star. Nice durable jacket too. Like it was made for TA connectors.

    charging NP-1's from DC? Solar?

    http://www.westmountainradio.com/product_info.php?products_id=epic-pwrgate Look into this device. I don’t have personal experience with it but you could in theory create a custom charging program that your NPs would be happy with. Would require some extra research, cable making and leg work on your part but could be just the thing. Also accepts a PSU input so you could have it switch over to an AC power supply when AC is available. I think the way way it works is it pulls from whichever source (battery or PSU) has the higher voltage and also keeps your battery charged via solar or the PSU input.

    New IFB system

    I would not want to be using a whole bunch of Duets on set mostly because they eat through batteries. About 6 hours on lithium AA and about 4 hours on rechargeables. Great for boom ops though.

    Comtek BST-25/216 on battery power?

    A trick I learned from Ron Meyer.. put a diode in line inside the XLR to knock the voltage down a volt or so.

    New wireless TX deviation rules October '18

    Are you going to mark the newer 50kHz units somehow on the label?
  12. Not sure combing pin 2 & 3 on the ring is correct. With the TA3 outputs I think you’d just leave pin 3 floating.

    Chicago rental shops

    Have a Lemo to BNC cable? Then just get an off the shelf 3.5mm, strip it and hot wire your tentacles. Should only need a few moments of contact to jam.

    Microdot to Lectro TA5 failure

    Or you can just take a scissors to that thing and get yourself a shiny new Switchcraft TA5F.

    Frequencies in Chicago

    Also when you scan on a G3 set your squelch to low to find the cleanest channels.

    Frequencies in Chicago

    You’ll be fine. G3s have a wide tuning range and I’m sure you’ll be able to find 3 clean freqs. If you need need any help while you’re in town get in touch with Gerry at Second City Sound. http://www.secondcitysound.com/

    How many channels?

    Lectrosonics issues

    Another way to look at it would be if you need 5dB of attenuation then it’s ok to run it at 0. The other big signal flow question is if it’s better to set your Sound Devices to mic level and then use something like -20 or -30 on the Lectro receiver since the line level setting on most Sound Devices machines just adds a 50 dB pad in front of the mic pre. So technically if you’re trying to minimize pre-amp gain you’d use the mic input and something less than 50 dB of attenuation on your receiver. Of course, then you’re running a weaker signal through your cabling which could be prone to inducted troubles and interference. In in an ideal world I think SD would add an option for a “-10 consumer line” setting which would match better for most wireless systems that aren’t a true line level.

    In ear monitors for production sound

    Are Etymotics any better? Also which flavor are you guys using since they have several variations on the ER4

    In ear monitors for production sound

    I’ve only really tried Shure in-ears but I’ve found I can’t use them on set as utility or boom because of all the inducted thumps and clicks and cable noise when moving around. Maybe this is inherent in all IEMs? I like them okay when I’m just sitting still.

    K-Tek Airo boom pole mods?

    Why not just measure the end of it?

    In ear monitors for production sound

    I have not used either of those products. I was a little discouraged by their lack of tech specs. I got the impression it’s a very small operation. I emailed them with quite a few questions. They answered some and then ignored a bunch too.

    In ear monitors for production sound

    Yeah you’re right. I was remembering the image on the website of the modules thinking they were stand alone. This would seem to fit the bill: https://www.limitear.com/products/limitear-fl/ Or this device which has some degree of adjustment and two inputs. https://www.limitear.com/products/adaptear/

    Mr Teas, look st the Canford website. They sell some limiting cables I’m pretty sure.
