DanieldH Posted June 5, 2021 Report Share Posted June 5, 2021 I want to refit my straight cabled QX5100. The plan is to mount some reel system on the bottom end, so a slim cable is desired. As I don't have any of the mentioned around I wonder, what to buy. What are your experiences with these cables or with DPAs slim XLR? What is the outer diameter, RF performance, bending radius of the DAO4010? Would the PVC coating of the 1804A produce significantly more cable noise compared to the cable Ambient sells? Thnx Quote Link to comment Share on other sites More sharing options...
Derek H Posted June 5, 2021 Report Share Posted June 5, 2021 I think you’ll just have to buy a few feet of a few different kinds and try it out yourself. I like the matte durable jacket of 1804a but the shielding is not the best. But it is quad so kind of a trade off. Reel system? Now that’s interesting. Will it be spring loaded/self winding or more like a fishing rod? Quote Link to comment Share on other sites More sharing options...

Will it be spring loaded/self winding or more like a fishing rod? I look out for fly reels, mainly on aliexpress. Quite a few offer some room for a mainspring upgrade in the future. Currently I need to choose a cable that works even without reels and springs, so I have some specs to decide on reel dimensions. There are various drag systems for fly/ice reels. Most reels produce a clicking sound, either as an essential part of the system, or they just imitate it as an audible user interface. The latter can be removed. Springs introduce a hell of issues that may be trivial for seat belt, dog leash and vacuum cleaner designers but not for someone with my resources or what a wireless microphone boom demands. The first is, these springs love water since they want to turn into rust, so a protective housing is necessary. A water protective housing with two moving parts is nothing I can just 3d print or buy in the right dimensions. I am open for ideas though. Another issue is, you'd need a backstop and release mechanism like a vacuum cleaner or a measuring tape. When I have a working reel, my next step would probably be to design some anchors to fit an unprotected spring and service it with WD40 regularly. In the 1960s and 70s, there used to be retractable "automatic reels", but they did not prevail. You can buy collectors items here and there, but they usually don't fit my specs and are old (as in, they break and are not easily replaceable) heavy, expensive and are designed for a lot more length than a boom cable needs. On top of that, I don't like the idea of modifying some collectors item. The reel will be mounted with its axis crossing the boom, opposed to usual fly reels: vs If I had the 3d modelling, printing and crafting skills, I'd go for a reel that spins around the boom. Whoever reads this, note this warning: Mainsprings are dangerous, protect at least your eyes and hands! Quote Link to comment Share on other sites More sharing options...
OnTheSoundSideOfLife Posted June 13, 2021 Report Share Posted June 13, 2021 Why not go with a coiled cable? Quote Link to comment Share on other sites More sharing options...
DanieldH Posted June 13, 2021 Author Report Share Posted June 13, 2021 My experiences with those are not that great (though old). These where not much, once a Ktech once an Ambient. Both produced inverted loops, that required constant maintainance, got stuck and were a pain especially in length>ceiling height stiuations. Another thing is, that I sometimes like to quickly slide the quickpole through the sustaining hand with soft gloves. That would produces movement in the cable and even a center of gravity shift. On top of that, a straight cable has a lot better ratio of overall weight vs center oft gravity, espacially with whatever cable foo on the bottom end.

DanieldH Posted June 14, 2022 Author Report Share Posted June 14, 2022 I am experimenting with some mods on my QX5100. I've replaced the velours and I am rewiring with 1804A. A friend printed me these disks that perfectly snap in on the end of the pipe and glued them with B7000. I'll see, how they hold. In first tests, it seems, that there is less cable noise with 1804A and the disks, but not as much as expected. However, the disks seem to help a lot in pushing out the cable keeping it straight. The 1804A is a lot less stiff than the original cable Ambient used, which is not a wanted feature for pushing out the cable. I am waiting for some spring loaded reels to arrive that I can hopefully fit the 1804A with. I'll continue in a new DIY thread. Quote Link to comment Share on other sites More sharing options...
tourtelot Posted June 14, 2022 Report Share Posted June 14, 2022 Way OT but what is your (and anyone else's) experience with B7000 glue. I am always looking for the better of two things; solvents and glue. Thanks. D. Quote Link to comment Share on other sites More sharing options...
DanieldH Posted June 14, 2022 Author Report Share Posted June 14, 2022 Well, it glues. I bought it for a phone repair project and I like the small tip that allows for precise application. I have never removed it, as of yet, but as I believe it comes soft with heat application. Cleaning petrol, Isopropyl, spirit, orange oil based cleaners would be my first approach.

osa Posted June 23, 2022 Report Share Posted June 23, 2022 What about the option of mogami w2697 - I use this cable for everything where I need thin flexible balanced cable and it solders really well https://mogamicable.com/category/bulk/microphone/lavalier/ my dad and my sons and I all went fishing recently and my dad brought his fly fishing rod and I could see how this concept would work as this cable is very thin and flexible very similar to fly line. I will for sure share this thread with him as he is not a sound mixer but does have an appreciation for our craft nonetheless and will get a kick out of it Quote Link to comment Share on other sites More sharing options...
DanieldH Posted June 25, 2022 Author Report Share Posted June 25, 2022 Thanks for the input. I did ask DPA some time ago what they used for the DAO4000. After some back and forth they said it is "3031-40 black" and seems to be the big brother of the 2697. When I did some spool tests, I was surprised, what difference 0.192mm in nominal diameter makes.
