The Leprecon 624 board has 24 channels. With soft-patch you can copy a board channel out to multiple DMX channels, but those channels will get exactly the same data. There are uses for this capability, and running intels is one of them. DMX-512 is a protocol capable of transmitting data for...

The SDR2496 is a hard-disk substitute for a 24-track open-reel studio recorder. No level controls because you're expected to use your mixing console for that. On the MRS1608 - it lets you record up to 8 tracks simultaneously. You can do a pretty good recording, either live or studio, with...

I'm assuming the white is the ceramic connector that connects to the pin terminals of the lamp proper. The focus isn't quite good enough for me to be sure, but I think that looks like solid, not stranded, wire. Stranded would be better, but either way it should be soldered to the connector...

When they do an instrument amp like that, with a built-in speaker, they usually design the amp for the speaker they're planning on using. Hooking it to external speakers may be a problem - especially if you're planning two or more external speakers in parallel. The lower impedance will make...

To fix my scaling problem I had to go back to the original board drawing and change the units to inches, then save it. Then I could load the cabinet drawing (in inches) and import the board and it was scaled properly. John

TurboCAD? Are they still around? I used to have a copy somewhere around here... a DOS version, back in the eighties. Anyhow, you might want to check the scaling - if the lights were built at a different scale than the lighting plot you're doing, that might be a problem. I had a similar...

Sounds like a problem with the way you've got the Lexicon patched into the board. I'm assuming you're coming out of a post-fader aux send to the Lex and coming back from the Lex through a channel instead of the aux return - good way to run if you need to EQ the effects. Is the channel...

Well, I've added the bill of materials as a fourth page to the .pdf file. If you've already looked at it, you may have to hit the reload button on your browser to be able to see the BOM the next time you look. I found Digi-Key catalog numbers and prices for everything. I did not include a...

Well, for Peter (and anyone else who's interested), here it is. The .pdf file includes the schematic and two pages of "theory of operations." No guarantees - it should work, but I haven't built it yet to be sure... there's one part (the relay) I didn't find in my junk box. Also, I'm still...

Let's say you hooked two consoles to the same universe. How do your dimmers know which one to obey? What happens if console A is trying to turn a light on and console B wants it off? The protocol was designed for a single console to avoid having to put that much intelligence (and cost) into...

DMX-tools is designing one. I may build one just to prove it works, but it's not something I intend to sell. What I'll do is post the schematic, parts list and theory of operations. It's up to you to collect the parts and build it yourself (or find an electronics-geek friend to build it for...

How much of an electronics geek are you, and how soon do you need it? Given a little time for me to design it and a little time for you to build it, it should take about $20 worth of parts. A long, long time ago, at Great Lakes Naval Training center, I taught the care and feeding of dial...

I wouldn't be surprised if they used a non-standard connector on an otherwise-standard monitor. It forces you to buy the monitor from them at an inflated price. John

More likely, to make the vocal sound distant, it may have been put on the two channels out of phase in the original recording. Through stereo headphones or speakers it's great, but mixing it down to mono, the out-of-phase vocals cancel. John

My new signature quote is a clue to my new avatar. Both indicate that I'm a rabid fan of Monty Python's Flying Circus. If you rent the movie "And Now For Something Completely Different" - the sketch containing my signature quote segues into a song about my avatar. Or just ask any other...
