hey guys So my kit has two Sony UWP series Wireless Mic Kits. These are only powered by two AA batteries. I know higher end receivers can be externally powered by a DC cable and a BDS system, but unfortunately the Sony's don't have a DC power jack. I'm wondering if there's a way to have a DC wire going into "dummy batteries" that would then power the receivers. I could then hook up the DC to my BDS. Here's what I'm working with: NP1 style battery, Hawk-Woods NP cup/BDS (Its the NPC-SQ4NS). The NP then powers a Sound Devices 302, and Sound Devices 702T from the Hawk-Wood's 4 pin hirose outputs. I basically want a wire that goes from the Hirose outpu…

I've never done a Snake cable that terminated in a DB25 connector but I was thinking of giving it a try. It's for an analog mixer to recorder connection on my cart. My first basic question is: I've made all of my previous snake cables (for my cart) using Canare Mini Star Quad (L-4E5C) and wrapped in flexo expandable tubing. Do I do the same here or do I use multi-pair cables like Canare L-4E3-8P or L-4E4-8AT? After that, I'll take any advice on DB25 connectors and making 8 channel snakes with them. Thanks, Josh

I’ve been working on a design for a small line mixer since January, on and off. I’m getting pretty close now- I’ve got a working circuit and managed to get the enclosure design working. I need to make a few tweaks to the board design, as some components need to be moved in order for it to fit in the box This particular one is an unbalanced design, with 4 inputs over 2 mini XLR inputs, outputting to a single mini xlr output. The reason for this is to work with my Sonosax recorder and mixer, in order to be able to be able to add the recorder’s 4 XLR inputs to a mix (on the bus in for the mixer) and still record pre-fade ISO tracks.…

Here's a technique I invented years ago for hanging a sound blanket. You need one C-stand with an arm plus 1 more arm and head. This set-up lets you stretch the blanket out tight and you don't have to deal with the No2 grip clips loosening up or popping off.

I have a Remote Audio TA3-dual XLR I'm chopping up to put a TA5 on. How does one go about wiring these? I have the diagram for the TA5 (Rean RT5FC-B ) but don't know where to assign the hot/commons and ground for each channel. Searched/looked online and couldn't find much. Thanks.

I have been wanting to build an external battery to use with my Zaxcom bag rig consisting of a Nomad 10 and Zax wires (QrX200 and 2 TRX's) for days when I am not needing to carry the bag and I can use my small cart. I'd like to keep in a small pelican type case and I am thinking along the lines of making it so I can power to my BDS so it would be a fast switch over from my bag batteries. I've been doing my own research around and trying to figure out the right setup when it comes to voltage, watts, amps, etc. I am a complete amateur at this so please forgive my ignorance. Like I said I have done some research but I wanted to also get some advice from the great sound comm…

Designed and 3D printed a "knob extender" for my MixPre-6. Even thick headphone jack connector still fits, but the knob has a better grip and is easier to reach when operated in a bag. Download the .stl file (for 3D printing) here: http://knowledge.lom.audio/research/mixpre_knob Or get it from our company here: https://lom-label.myshopify.com/products/mixpre-knob

I decided it was time to improve my power distribution; I've been running multiple power supplies for my F8n and 302 and want to simplify things. I also want to be prepared for more bag work down the road. I'm trying to save money for mic upgrades, so I figured this would be a good place to go DIY. To give credit where it's due, I got the idea for the BDS here: https://henrirapp.com/diy-hirose-battery-distribution/ And grabbed the power meter circuit from here: https://learn.adafruit.com/pro-trinket-power-meter/overview?embeds=allow The hardest part of all this was getting the dimensions on the 3d printed remote housing correc…

I'm going soon to Qatar to film a documentary that is pretty much Qatar in the eyes of a blind man. Yes i did write it correctly so you can imagine how important sound is and specially atmospheres. So i wanted to buy a binaural mic that i could record some nice atoms with during shoot and after. As mostly is going to be during the shoot, i wanted something small and unobtrusive as i am by myself. Surround mic was a nice idea, but neither budget or space allow for it, and the only small one (Sanken WMS-5) is not available to rent in the UK. Looking at good small binaural microphones, i realised most are just two good omnis tweaked and positioned to work as 1 ste…

As promised: Two circuits: the first for unbalanced 9v operation, the second (which is what's inside the DPA 6001 adapter) for balanced 48v Phantom operation. Best to check with a mic you don't mind losing if you're not sure about construction. Don't blame me if it all goes wrong! Regards,

I am trying to solder LEMO 3pin connector for SSM transmitter soon. But I figured the pins inside LEMO are so tiny and the bigger problem is Cos11d's wire itself is so fragile and thin specially white wire. I searched here and there...but not easy answers for me. Anybody can give some tips?? Pre-soldered Lavs are kind expensive.

So after pouring over countless T-slot cart designs I’m about to put in my own order with 80/20 for a custom cut and milled kit to build a smallish, collapsible follow cart. Wondering if any of you who have done the deep dive into extruded aluminum T-slot contraptions would have any general advice? Things to watch out for or design mistakes to avoid? Connectors you hated? Some specific questions I have.. how does the anodized black framing stand up to wear and tear? Anyone use the “Central connector”? Thanks! Derek

Here is my first attempt at making a small LiFePO4 battery pack. The parts shown are: $10.95 Pelican 1010 Mico Case $31.60 (4x) LiFePO4 26650 3400mAh cells $6.45 PCB-LFP12.8V2A Protection Circuit Module $31.95 H01280007-US-D1 LiFePO4 12.8V 0.7A Charger $7.04 (8x) Keystone 87 C Battery Holders some solder, some hookup wire, glue, and a spare 2.5mm female jack Total cost was under $90. For a 3.2Ah battery pack, this may not seem like a great deal. If you take out the cost of the charger, it is around $60. A Sony NP-F970 is $103 from B&H and is 6300mAh @ 7.2V, so these batteries probably have about the same power, only the cu…

I'm planning my first cart build, and was looking at the Gallery of Sound Carts to get some inspiration. Now - I am wondering what those rails are that most of you are using to build your custom carts? Can't seem to find anything on the internet or in the shops... I mean the rails that you can see on those carts: http://jwsound.smugmug.com/Gallerysoundcarts/i-bxhngc4 http://jwsound.smugmug.com/Gallerysoundcarts/i-6mLgLJV Any hints? Or any suggestions for similarly useful rails systems?

I'm about to make a battery charging station out of a Pelican or HPRC case. The purpose is for the case to hold AA/AAA chargers, 9V chargers and NP-1 chargers plus their corresponding power plugs and a power strip in the same case so all I have to do is open the case, plug the power strip into an extension cord or wall socket and I'm ready to charge anywhere. I know many of you have already done this, but I can't seem to find the posts. I tried searching all of the regularly suggested ways but to no avail. That said, I would love to consolidate information about this sort of thing into this thread if possible and see photos of what you guys and gals are using for …

My M216 lives in my bag 100% of the time and I'd like to power it with the BDS. Comtek tech support basically came up with the same idea as me: Fashion a wood block to 9v battery dimensions, mount the appropriate terminals/wire and power it with a regulated 9v feed from the BDS. I've looked at the ISO9VOLT but the connector is in the wrong place. Before I put this together has anyone come up with another solution? -Thanks

Here's my latest project: a 9v power distribution box. Many factors led me to make this custom distro unit. 1) I use Audio Ltd and Micron radio mics, both of which want 9v external power. Microns say they'll take 7.5-16v ext power, but they say ALWAYS use their custom cable, which has a 9v regulator built in. And Audio Ltd specs say they'll handle 9-14v DC, but NP Li-Ion batteries at full charge will put out 16v. I don't have the luxury of the 10-18V range of Lectro's. 2) Of the off-the-shelf solutions, only Hawk-Woods has a 9v-regulated distro box. The BDS, from what I can tell, passes along whatever voltage it receives. 3) My Microns don't have a pilot tone to …

So I have these sennheiser g2 packs lying around and decided to attempt a wireless timecode system with them. I built a lemo-1/8th cable to output from my fusion, and took the sensitivity down to -30 on the transmitter. Meters read a solid -10 or so when plugged in. The receiver is getting the signal cleanly with no hits, and when outputted to a ts-c in read mode, it will scroll if you touch the chassis of the lemo connector. If you do not touch the chassis, it will lock a static number once and not scroll. In gen mode it does nothing. The ultimate goal is to wirelessly jam a red camera, but the red won't flash its little chain symbol and it shows no indication of com…

I'm starting to think I should make a multi-cable camera snake for convenience's sake. I'm running a 633, occasionally people will want double-system or even single-system on camera, and I might have to go wired. Currently, I've been using separate 10m XLRs and checking the return on headphones before we roll, but I'm thinking things could be easier. I'd like to make a camera snake with 2 XLRs, a 3.5mm TRS return cable and perhaps time code on BNC. What would be an appropriate length and how could I manage to bundle the cables? I'm probably looking at cables of different diameters. I'm thinking I'd like to have access to the individual cables as well if necessary for main…
