Subject: Re: USB Microphones Date: Sun, 23 Jan 2005 06:53:41 -0500 Of course, "quality" can have numerous meanings. There are two components involved here. The "microphone" that converts sound to electrical impulses and the A/D which converts those impulses from analog to digital. Exactly what are you looking for? Quality audio, highend A/D, or just rugged construction? Besides the solutions presented you could also purchase the microphone and the USB A/D separately. Interesting that the Beyer mic David posted doesn't show their A/D specs. All that quality lost if it's only streaming 8b/11kHz.

Delbert, my best guess is the head rigger was well intentioned but incorrect. I would guess he was told you should be wary of connection of steel and aluminum and incorrectly deduced it is due to dielectric properties as opposed to Bill's above explanation. While there will be dielectric properties as others have noted they are minimal in most of our applications compared to the abrasive properties. A note to all. I am probably halfway into my theatre career and have been in the place of the head rigger. I believe I am always well intentioned but sometimes I am just wrong due to misinformation or I improper deductions. We are never too old or experienced to learn. You must always be diligent in you quest for safety and know when to stand your ground, but you must be wary of the fine line between KNOWING and BELIEVING. Keep up the good work everyone.

Yes Frank, we do know what those clamps are over here. We use them in fact; a variation seems to be standard on a lot of moving lights. I suspect the big reason the cast-iron clamp is popular here is that the same clamp can be attached to a variety of pipe and tubing sizes, everything from 1" i.d. pipe to 2" i.d. It's "one-size-fits-most". The G-clamps as you describe them which I have seen only seem to work on the one size pipe it's designed for. Maybe you folks are more "standardized" than we are. I've seen 1 1/4", 1 1/2", 2" pipe, and structural steel tubing all used as electric battens, and I've never even toured! The same U.S. style clamp would fit on all of them. -- Mick Alderson TD, Fredric March Theatre University of Wis.

Also, aluminum oxide is highly abrasive, hence aluminum-oxide sandpaper. A layer of aluminum oxide becomes a high resistance in the circuit, and eventually becomes a voltage drop running so hot it can start a fire. The special pastes, etc., that are available for copper-to-aluminum connections lock out oxygen, reducing the rate at which aluminum oxide will form between the two metals. The problem is not with the aluminum, it's with making a good connection between it and something else. Truly a dissimilar metal issue.

Anyways, there are tons of hotels close to the convention centre. However, not too many are reasonably priced. There's a Holiday Inn on King St. close-by, which for that weekend, go for US$130/night in March (CAD$159). Check out http://www.hiok.com for details. However, from some meetings there, I have a bunch of coupons for something like $25-50 off (I think)...contact me off-list if interested. For other housing, check out http://www.toronto.com/section/accommodations/ and click "Accommodations By Neighborhood" and select Downtown. Basically, as with any city, the farther you stay from downtown, the cheaper. Wherever you're staying, try to stay central as possible (ie. Not the airport) and then you can get to the convention centre easily via subway.

Message-Id: From: Jason Romney Subject: Re: Scholarships? Date: Sun, 23 Jan 2005 13:14:31 -0500 Mike, Most decent college theatre programs offer departmental scholarships. That's probably your best bet. Find a place that you want to go to school and apply for their scholarships. This way you're competing with a smaller applicant pool than you would with a private scholarship program and they're specifically looking for people with talent and skills in theatre. That's how I did it. I got my entire BFA tuition paid for with scholarships from the theatre department I was attending. You don't mention where you're from. There's probably a High School theatre conference in your area. Most of them have group auditions/interviews with representatives from area colleges. Go to the conference and get your name on the list for the group interview. Then you can get together one on one with the schools you're interested in. Ask them about their departmental scholarships and get applications for all of them. Here's a little tip from someone on the inside. The schools need you just as much as you need them. So find a place you want to go to school, when they accept you, explain to them that you need financial aid in order to attend. They'll help you find the money because they know if they don't, someone else will, and you'll go there instead. Be aware that even the best scholarships don't cover all the expenses of attending college. Be prepared to apply for government grants and subsidized student loans in addition to your scholarship money. The college theatre department can help you with that as well. The money is out there. Even for theatre majors ; ). You just have to know where to look.

I'm experiencing a bit of a "midlife crisis" (though, those of you who know me would probably scoff at the idea) and am in need of some advice. Basically, I've led a bit of a whirlwind life in this business, have covered a LOT of territory, and have had life experiences that would bely my outward appearance. I never would have gotten to this point if it weren't for my excellent teachers and mentors, and would like nothing more than to "repay the favor" in an educational setting. Not full time mind you (I still enjoy outside work), but possibly as a guest lecturer/workshop instructor. Any time I've tried to pursue this angle, I'm generally met with the attitude of "but you're still so young, why aren't you WORKING?" etc. I would love to still be on tour, or traveling, but I have a daughter who lives in NYC and since I actually WANT to have a relationship with her, I'm kind of barred from being gone for long periods (even though I've had to do that the past few months).

I'd be more worried about the history of a piece of truss (has it ever been involved in a failure, run over by a forklift, broken and re-welded, etc) then about a few pieces on cable wrapped around it. You could always put a piece of Gaff tape between the truss and cable, if it make him feel better.

If Playlist Mode is on, it will show that in the title bar at the top of the affected cue list, in brackets. {A} Cues - List XXX [PlayList Mode] If this is the case, Go to the Cues menu, and investigate the list your having an issue with and see if "Playlist Mode" is checked.

We are pretty much standardised on 48mm pipe and truss in the UK You can get hook-clamps that accomodate 20mm-50mm pipes but most folk just use standard 50mm clamps. One issue with a hook clamp is the M10 wingbolt that tightens onto the bar can damage aluminium truss as the force is applied on a very small area. Over enthusiastic tightening can leave a little ding in the tube. Many companies are now using hook clamps with a captive clamping plate to protect the truss (it also gives a much stronger hold - much better for overhanging) Ian Cunningham Solus Technical Services ------------------------------ Message-ID: <41F41893.1050209 [at] fitchtech.net> Date: Sun, 23 Jan 2005 16:35:15 -0500 From: Adam Fitchett Subject: Re: Scholarships?

In-Reply-To: As a current college student, I would recommend seeking out non-theatre specific scholarships as well. There are typically many available that aren't program specific. Also be sure to spell check and proofread all communications, especially when writing emails trying to get info. (Specifically: majority are few returning students.) If there is a typo it looks poor on your part and doesn't help you stand out they way you want to. I realize that this is just an email list, but through this list and the theatre sound mailing list, I have managed to make contacts, get an internship and, just recently, I got a new job in NY which hooked me up with a new school and is helping pay for it.

So, this question is just for my education. Why do people use the digest mode? I get the single messages, and I have a sub folder in my inbox for stagecraft, and a simple filter that puts every mailing from this list in there. It threads all the messages, and I see them as soon as the list resends them, instead of waiting until the digest batch goes. I do not have to look at the list until I want to, and I can much more easily search back in my own archives for specific posts or addresses. I guess if you paid for each incoming message, the digest distills it all down better, but the number of bytes is still close, so usage charges and time online should almost be a wash.

There is a table which places the metals, and Hydrogen in order of activity, called the Electrochemical series. Potassium is the most active, and Platinum the least. Basically, the more active metal loses to the less active. There is a lot more to it than that, and alloys complicate the question, too. This is why galvanising works. In a corrosive situation, and its Oxygen content makes air somewhat corrosive, the Zinc corrodes rather than the Iron. Boats usually sport a Zinc 'sacrificial anode' electrically bonded to the prop shaft and the whole electrical system. This saves the important bits, but needs replaced from time to time. Aluminium has similar properties, but more so. I guess that you are thinking of crimp sleeves, which may be copperish or aliminiumish. Neither will be pure metal, but alloys. At a guess, the coppery ones will be a cupro-nickel alloy: I don't know what is alloyed with aluminium. My old Chemistry textbook takes no account of this sort of thing. It is what allows you to predict the voltage produced by batteries. By the table, a Potassium-Silver cell would have a terminal voltage of 3.7V. But the table is not comprehensive. Lithium is even more active than Potassium, which would account for its popularity in small, heavy duty, cells. This post includes a number of possible references to search with Google. The sites would be of interest. I have a show on at the moment, and so less spare time.

Tell it not in Gath, but you can do this with ours. Suitably placed bits of wood will allow their use on smaller pipe, and a big hammer will adapt them to larger, and put them back to standard afterwards. Mild steel is a forgiving material.

Does this trussing/rigging need to be reliably grounded for electrical safety? If not, then I agree with you.

Sorry -- I always look at everything from an electrical perspective, even when it's completely meaningly or even inappropriate. :) That Maglight has an anodized coating -- oxide that is produced by electrochemical means, carefully controlled to result in smoothness, consistent thickness, and so on.

Except that ground currents and inductive currents could be flowing through your trussing and other metal rigging components. These can induce electrochemical reactions, creating electrical barriers between components over time. My apologies again, it may not matter the slightest little bit.

I wish this were so in Massachusetts. The latest state elevator code specifically mentions stage lifts as part of it's applicability. Of course there is no language in the code that defines what a stage lift is or how it must conform to code. The manufacturer was required to hire an elevator company to install the thing instead of ironworkers or stage hands. I think we are about to experience the first actual application of this new language here in about 2 months. What the inspector will say when he sees our double decker spiral lift smack dab in the middle of the stage should be interesting...

I am using two 24 dimmer ETC Sensor Racks. These use three phase power. Okay, fine. This three phase power comes from a transformer, which as I understand it, separates the three phases of power from a single conductor on the primary side to the three separate conductors on the secondary side. The labels on the transformers (from memory) identify the HV side to be 440v, and the LV side to be 208v. A 90A breaker energizes the transformer. The way I understand this, a single conductor having all 3 phase on it at 440v comes into the panel. The 90A break straddles this leg to neutral, limiting the current it carries to 90A or 39600 watts max. If this is the case, then why does this breaker trip when it has 16k of lighting on it? -- Mat Goebel Cell: 510.693.1448 ------------------------------ Message-ID: <006701c501f5$bf50b540$0800000a [at] Tony> From: "Tony" Cc: mgoebel [at] gmail.com (Mat Goebel) References: Subject: Re: Three Phase Power Date: Mon, 24 Jan 2005 09:18:57 -0000 I don't think the working out of 3-ph power is quite that simple, though it's been a LONG time since I've looked at step-up/step down calculations! It's also a bit early in the morning to get my head TOO seriously round the thought, but I'll give it a try.... I find it odd, however, that you have the 3-ph single feed coming in to your building with the phase separation carried out on site - I'm sure it's feasible, but these days I'd expect it to come in already split.... My brother is a full-time commercial sparks and after checking with him, he agrees that it's VERY unlikely that you actually have all 3 phases incoming on one L/N/E cable. He, like me, suspects that what you may actually have is a 3-ph 5-core feed going into a distro box, which then separates to 3 separate beakers when it SPLITS into the 3 separate phases. This would then make sense of the labelling - 440v at the big feed end, 208 (or whatever) at the individual phased ends. So - to clarify the situation, some questions: Are you SURE that the boxes on the walls are transformers? You should really have a 3-way 3-ph breaker on the main incoming and a set of single phase breakers on the individual outlets, though this isn't always the case on older installs - do you have other breakers? If so, how are they rated? They may NOT be as high as the 90A you have incoming. Is the Sensor rack the only thing fed from this incoming feed? It may not be obvious, but there may be tails off to other parts of the building with heavy loads that will contribute to the overall limits. (For example, we have a 300A 3-ph main incoming, but hung off that as well as the lighting is the rest of the building's power, along with a 3-ph 100A per ph heating unit for the auditorium!) Are you sure that the rack is cabled in 3-phase? If not, then the max capacity is reduced from your 39600kW to just over 18.7kW, which is significantly closer to the 16K you believe is tripping the breaker. (Assuming the 90A is a 3-ganged all-in-one breaker, any excess on one phase will physically cause the trip of ALL 3 phases, which sort of suggests that you may NOT have the individual phases protected individually). This is all conjecture, of course, and you were right in your first assessment in that the only way to get a valid answer is to have a qualified sparkie come look at the installation - there's only so much we can do, unfortunately, with just words to describe the picture. Let us know how it turns out.
