i am in the midst of making up a digital input cable for a 788 and want to make use of the remote roll feature of a cooper 208 (not mine, otherwise i could get a voltmeter to it) and am struggling to work out from the cooper manual how i should wire the logic in and ground connection from the 788 to the TA5 on the back of the cooper. the pin outs are pin 1 = -10v (nagra) pin 2 = stop (nagra) pin 3 = pause stop (dat) pin 4 = common (dat) pin 5 = record (dat) but i cannot find any info anywhere about which i should connect to pin 9 on the 788 DB15 i guess it would be either TA5 pin 5 to DB15 pin 9 and TA5 pin 4 to DB15 6 and 7 or TA5 pin 1 to DB15…

I want to connect a power source (BDS v3 Battery Distribution System - you can see it at B&H) to an Edirol Audio Recorder (R-09HR Portable High-Resolution Audio Recorder) so all my equipment has one battery source. Can anyone tell me what connectors I should use? Thanks mailto:cbj@srcq.org

Ok, so I've decided to build my first sound cart but since I'm still a newbie I'm not quite sure what the "ideal cart" would have. So, would you guys be so generous as to share your thoughts as to things I should consider in my build? Any info is greatly appreciated. Thanks, Mike

Hi all, This is the working prototype for my homemade bloop slate. It has 9 superbright LED's (very bright), a momentary push button that triggers the light AND sends a 400Hz tone to the mini-jack (line level-ish) that you see next to the trigger button. It works well when feeding the Mix-in on my SD302. It all runs on a 9V battery and I believe it draws about 100ma. I hope to add either an LCD display/counter to show take# or just keep it simple and add a layer of white dry erase board and handwrite take#'s. Some other possible tweaks are- trimpots to adjust brightness and frequency and a small amp to drive long audio lines if necessary. Let me know wha…

I'm replacing some cheap aluminum radial caps in an LCD monitor. I know about Electronic City in Burbank but I seem to recall looking for some mic components there in the past and they didn’t have some of the resistors or capacitors I needed so I ended up going online for them. I'd rather not wait for delivery and, instead, be able to walk in and buy locally. Being able to talk to helpful, knowlegable, staff is another reason I'd like to stay locaI. Thanks in advance.

Trew audio makes a boom caddy to hold boompoles and occasionally sit on for a hefty price Wanted to see if anyone else has done a DIY boom caddy similar to this and would like to share some pictures perhaps.

So, I work with a cameraman who has had some bad luck with the flip-out screen on his XDCam. It has been replaced a couple of times already (from getting bashed!) So he now shoots with the screen all closed up! I can no longer read the meters over his shoulder so I came up with this little box that shows me when audio is present in the camera. I primarily use the Zaxcom stereo hop as a camera feed with a backup recorder running in my bag. It runs from a 9V battery and has separate left and right (Ch1 & Ch 2) LEDs. The audio feed comes from the headphone jack or 5-pin audio out. Dimensions are about 2.5" X 1.5" X 3/4".

Hey guys, I just received a second hand Lectrosonics mm400c today. I put a brand new battery in and tried to power it up, but had no success. Long story short, here are some steps I found useful for a possible quick fix. If the LEDs do not turn on then chances are the switch is to blame. The housing of these units is fully enclosed and power on is done with a magnetic button through the outer wall (waterproof design). Sometimes magnets might fall too far out of alignment and need to be sent in, but give this a try before the hassle. Picture 1 shows the magnet switch at off. Slide it to the middle where you will see to nubs that hold the button in tact expos…

I have a couple of questions about direct output mods for a mixer I have. I hope someone can give me a little more insight. The mixer is a JVC mi2000u. I've contacted JVC and they no longer provide support for this old beast. My plan was to tap the hot signals from the PFL switch, and was told by a former teacher and electronics guru to ground as close to or on the power supply, and I could even ground to the main output if need be. I was going to use a 9 pin d-sub with a breakout on the other side, as I've seen others here use. The advice I got was to use a heavier gauge wire from the ground of the power supply to the dsub on the back panel because: "Any c…

Over the years, there have been occasions where I have turned down my Comtek feed in order to mute it from the listeners between takes, and then forget to turn it back up when we roll. Since there are times when it's appropriate for the sound crew to keep the mics up for our own technical reasons, but at the same time keep the mics muted to the "public", I needed to make myself some kind of reminder to unmute the feed when we roll. I finally built a simple little box that would switch off the Aux send to the transmitter and at the same time, flash a bright red battery-powered LED to signal the muting. Turned out to be very useful.

Hi! I want to record some foley footsteps in different surfaces, I know that footsteps in sand, grass and stones (and others) use to be simulated with kinda trays like this and i know that the best way to have a good sound for footsteps in thick and solid surfaces like cement or concrete, tiles, marble etc... is to have it built in the very ground like this unfortunately I can´t have it... so I want to make a few DIY transportable surfaces (around 1m square) and I would like to know how to avoid unwanted resonances in surfaces like concrete or tiles. I appreciate any advice and every experience about how to record foley footsteps properly…

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…

Using the Pelican 1300 for a batt case is pretty common, and several sound houses have long sold custom assembled ones. However, it has been my observation that the resulting weight clearly exceeds what the Pelican 1300 was designed for. As such, I've always been attentive to the pins that hold the handle to the case, which can be problematic on Pelican cases in general but pose a substantial safety concern here. On the 1300 the pin can easily work its way out of one of the two thin blades of plastic on each side of the handle, and you might have a drop occur. You do not want the battery-loaded case falling on your foot or anyone else's. Here's a simple mod I did to …

Hi all, I'm currently in the process of building a manual switch box so that I can switch between 2 sources into 1 input on my 552. The two sources are a fig8 mic and a line level out radio receiver. I'd switch to the fig8 mic when recording ambiences and switch back to the radio receiver at all other times. I did have a thought of making the switch box a bit more elegant by having it automatically switch when phantom power was applied. I would only need phantom power for the mic so I could maybe set up a relay energise via phantom power and switch contacts over to the mic. It would save having to dig into my bag and also avoid accidentally knocking the switch …

Why? I have been kicking around the idea of a mixer with a crossfader for a long time now. Maybe it is from my days in NYC where I toyed around with DJ'ing (failing miserably) but I have always been enamored with the idea of using the DJ style crossfader. I searched long and hard, looking at almost every DJ mixer out there, to find something that I could adapt to my workflow. Nothing but the Allen & Heath XONE mixers came close, but not close enough, by a long shot. The XONE 464 is basically a WZ3 class mixer with some phono / stereo center section added, but was not adaptable to my needs. I found this baby randomly, absolutely no information on the web about it …

I welded some handles to my rt 10 cart. They make a huge difference in the manuverability of the thing. The top deck when bolted tight makes the cart a lot more rigid. I used scraps I had lying around so it didn't cost much. I used water pipe (mild steel) 1/2 inch inner diameter for the handles because the outer diameter fit BMX grips perfectly. The deck is made of plywood with square steel bars that hold the whole thing togther. Undo the 4 bolts that hold the shelf to the cart and it folds down, and even with the handles sticking up, fits in the trunk of my tiny Hyundai. Rakesh
