You probably all know this already, but remember that the PSTN (and ISDN) will be switched off by the end of 2025, so everyone is going to be facing this conundrum pretty soon.

Hi Rose, welcome to Blue Room. Just in case you didn't realise, you are replying to a thread that is almost 3 years old. That's not a problem, and I think everyone in this discussion is still a frequent contributor to the forum, but it is always worth checking the dates.

I don't see any way of reducng the load to 100% of the weight of the kit. You yourself have already mentioned 50% of force to lift. Even using 10 blocks only reduces it to 110%, friction cannot be ignored and as more block are added the friction is increased along with the additional weight of the lifting tackle. Equally the snatch force has to be considered. Yes. My bad!. I meant to type 150%. Slip of the keyboard. And I was unclear when I stated '..but the force applied is halved.' That, of course, is the force applied by the person pulling the line, not the force applied to the rigging point. Basically, my comment was somewhat less than helpful.

Ignoring the dynamic load and friction, this could be reduced by using a multiple-block arrangement (e.g. a Gun Tackle using two pulleys reduces the force on the rigging point to 100% of the load). You have to pull the rope twice the distance but the force applied is halved.

This is the VAT number on the Thomann invoice Vat Reg. No: GB 227385494

Part of an email conversation between our Finance Dept and Thomann UK over the last couple of days. "Thank you for your recent orders. As of July 1st, we have simplified the ordering process so that the online price displayed on our website is the total price you pay with no additional fees paid to the couriers. The VAT (20%) and handling fees are now factored into the final online price. Following the trade agreement between the EU and UK in early 2021, our pricing system was adjusted accordingly to comply with the new customs regulations. As a result, the prices displayed on our website were net prices as the VAT (20%) and handling fees were paid to the couriers on delivery. Please also note that based on the new trade agreement; it is no longer possible for us to invoice VAT registered customers excluding VAT and VAT (20%) will always be charged by Thomann GmbH. VAT (20%) will be applied and the invoice split between the net value of goods and services, the rate and amount of VAT, and the total value of the invoice."

Hi John Welcome to Blue Room. Just to point out that you are dabbling in thread necromancy. The most recent post before yours is over 10 years old.

You need what Flints call 'Scene Shifters' - also called 'Turtles', triple wheels, and probably lots of other names Three swivel castors on a triangular plate which itself is on a swivel. These are often used on scenery that has to spin on the spot and/or change direction without 'kicking out'. They are expensive, but not impossible to make yourself https://www.flints.co.uk/pdfcatalogue/castors.pdf

Would inrush current to a cold filament be enough to tip it over the edge, or would the fuse cope because it is HRC?

I had wondered about something like that. It would mean familiarising myself with the Mac and its ways, but that might be no bad thing. Questions arising: Would I be able to convert my wav files to whatever the appropriate Mac format is without loss of quality? Does the free version of QLab permit mixing from cue to cue and/or playing a specific spot cue over a continuous background? In rehearsal and our few tryout shows I've been handling the sound from a Windows laptop running a package called Cue Player Pro which does allow these and I've been expecting to have to simplify the sound design to remove the necessity (imagining that the software isn't widely used professionally). QLab will almost certainly play back the wav files without any changes. The free version will allow you to do what you need. https://qlab.app/docs/v4/general/features/

The defence seems incredibly flimsy

Hi Jeff, Welcome to Blue Room Just in case you didn't spot it, the original posts on this thread are almost ten years old. Take a look at the profile of the person that said they had the drawings. If you don't recognise their name, google them. Then take it from there.

But that is Thomann's choice. They could deal with the VAT and duty on all orders if they wanted to. Plenty of suppliers to the UK do, I buy product for manufacturing from the US and China and all my suppliers deal with the VAT and duty up front. I am far from knowledgeable about VAT, import duties, etc. But you seem to be suggesting that Thomann are just being bloody minded about it which seems unlikely.

Do you mean asbestos? whilst fiberglass aint nice stuff its not really a concern I read the word 'fibreglass' but in my head it was translated into 'asbestos' because I subconsciously knew that was what was meant.

I think Thomann have been pretty clear with the situation.

I can't remember who said it (it might have been me - the little grey cells aren't what they were) but the noise we lampies and vidiots make with fans and motors is equivalent to the sound engineer mounting a couple of 60 Watt light bulbs on the main speakers and leaving them switched on.

This was probably also because of the optimum viewing angle of the screen material. Different types of screen are optimised for viewing at different angles. There is usually a compromise between wide viewing angles and screen gain/transmission/brightness.

At Derby Playhouse we used about half a dozen of those colour changers with the control box until maybe the late 90's. I then repurposed them as projector shutters and used them until the early 2000's. I think I have a picture of the controller somewhere but haven't been able to find it quickly. The wheel had small magnets attached and the position was read by a reed switch on the mounting frame. They were a lot quieter than scrollers.

Deary me! We are all getting in quite a tiz over this aren't we? Perhaps everyone should just check the original post. "Does anybody know who we can turn to for design" seems to be the main thrust of it. So trotting out the old 'if the OP is asking then they aren't qualified' is somewhat redundant. The OP doesn't seem to be asking us for a solution, or instructions on how to DIY. They just want a name and number. Quite possibly a ground support truss structure is not the best solution, but the designer they have asked us for can decide that when they have looked at the job in detail.

I'd usually describe it as either the 'setting lline' in theatre or DSE (downstage edge) in concerts and events. Personally I've not heard of 'Plaster Libe' before but if you used the term I'd certainly know what you mean! My understanding of Plaster line is a line that touches the upstage face of the proscenium arch. So no good in a non-proscenium theatre. Setting Line is more universal but is always defined locally.

I have the same issue with the 560Z without a terminator.

I get this with the 560Z and other similarly priced fixtures. I have not found a solution other than making sure there is always a DMX signal present.

Any update on this? I have the same problem and I'm looking for possible fixes Thanks also to Whiskers for very helpful post, especially re pitch change matching refresh rate... Welcome to Blue Room, Ian. Don't be too surprised if you don't get a response to this. The thread is 6 years old. It might be better if you start a new thread with your specific circumstances.
