There used to be an organisation called LACORS (Local Authorities Coordinators of Regulatory Services) which was part of local government, and there used to be some people there who 'got' our industry. As such most local authority requirements were standardised. And then came cuts to local authority funding and they disappeared leaving a large hole in some local authorities knowledge.

It has the same problem many installation mixers have - gain controls on the rear. The MZ-372 is a lot closer to what I want... https://www.thomann.de/gb/tascam_mz_372_mixer.htm ...but for that money I can get an XR-18 and have change. I'm still very undecided if a pad-based interface will work for me. [E2A] And for the same money, an XR-18 and something like an Akai MIDImix for some real knobs if I need them.

How does that work? It's not mentioned in the manual at all; how I miss block diagrams showing the actual internal signal flows in mixer manuals.

I would buy a decent quality connector with tuned contacts and avoid the cheaper stamped ones at all cost. For the sake of a few quid it's not worth it.

The effect from a dome is quite spooky.

Nice, but a bit expensive. I also find the look of the Soundcraft a bit odd. I've looked at the 7.3 and various similar looking units. The problem is the rear gain controls. For my situation that wouldn't be an issue. A quick web search does throw up some audio-over-wifi solutions, some aimed at assistive listening.

I have a requirement for a simple mic/line mixer with 4 or so channels, to be used as a 'toolbox' mixer. Must be rack mounted and must have PFL. I don't want to rack a 'normal' mixer as they are too high, ideally it should be around 3U or 4U. In the analogue world, apart from a load of odd DJ mixers I can only find this... https://www.thomann.de/gb/the_t.mix_rackmix_821_fx_usb.htm Many of the others don't have front panel gain controls which makes them tricky to use with unknown sources. So I'm wondering about a digital mixer. Either something from Soundcraft from their 'Ui' range or Behringer 'X Air' or Midas 'MR'. 1) I assume the X Air and the MR units are identical. I certainly can't see any difference. 2) Does anyone have any of these and what do you think of them? 3) If I wanted to run some real faders from a small MIDI surface are their any gotchas?

If the OP goes that way then I have three 60W Millbank units sitting here doing nothing!

I'll blame Martin for that mistake as the schematics reference "CPU Board" and "Step Driver Board" even though they are on the same board.

On the '600 the motors are driven by the PBL3375 chips, which are in turn driven by the PBM3962s, which also control the drive current (=torque), which in turn receive a reference voltage from the main CPU. So it could be a wiring fault between the CPU board and the stepper board.

So if you were feeding tone, at full power, and if the amp produced the claimed power, you would consume 800Whrs. So 33Ahrs at 24V. Given it's a system for occasional speech use I'd reckon that a figure closer to one tenth of that would be more realistic. I wonder what the quiescent consumption is?

How much power, in total, do you need and for how long?

These do die.

That's the point though isn't? The allegation here against those desks is that there are running Avo's software, not some software that looks and feels like Avo's but which has been written to behave like that, but the actual binaries owned by Avo. And to do that the chips inside would need to be connected up in exactly (or at least very closely) the same way. Had I the spare cash then maybe I'd buy one to do a teardown. I'd hope Avolites have.

Absolutely. All this talk of 'illegal' seems to be based on second- or third-hand anecdotal 'evidence'. The moral question gets a lot more complicated.

But writing code that reads a closed-licence but freely available file format is different to making hardware which will run proprietary binaries. I'd like to think that someone knows. If those Chinese desks aren't using the same family of processor chips and peripherals then they can't be running someone else's binaries. But in most cases that's not illegal. [note: I have some experience in this field as a company I worked for was involved in a large ground-breaking patent infringement case which is still cited as case law in most any legal book on the subject that you pick up.] You're right. On the one hand it's actually doing something illegal and on the other it's thinking about it.

Hmmm, I do wonder how many of those people berating Paul, for openly thinking about something that many of us will have considered, can honestly say that they have never installed any unlicensed software on their PC? Be it cracked software, a keygen, installing a second copy on your laptop as well as the desktop, borrowing a mates serial number, using student editions when you're clearly not, or using software for a commercial end when such use is prohibited. Let's face it, none of us read the licence and really know what we're allowed to do under it, but that's no defence. [E2A] Does anyone DEFINITIVELY know that these desks use stolen software from AVO? There is a world of difference between software which is written to look and feel like another, and simply taking an existing executable binary.

£500 or thereabouts buys you the real thing... https://www.ebay.co.uk/itm/Avolites-Pearl-2004-DMX-Lighting-Desk-/383982780467 https://www.ebay.co.uk/itm/Avolites-Pearl-Tiger-Lighting-desk-/383999747303

Why not go for a PC based solution, eg Chamsys or Avo, and add a MIDI control surface for faders?

Anything with decent audio transformers goes for real money. Those Lundahl transformers in the Drake rack will ensure it fetches a good price on eBay if you decide to sell it.

Indeed. Plug some numbers into this... F = A x P x Cd ...and F gets big real quickly.

In the last 18 months or so there has been an HSE prosecution of a building company who failed to properly secure a ladder against use after a child climbed it and fell off.

And what are you going to power that off? PLUS...we don't seem to have resolved the 'what are you going to hang the lighting on?' question. By my reckoning your ring is 7m across the diagonal. To keep glare out of the wrestler's eyes when they are in a corner the light will need to be 45 degrees up, and lets say a wrestler might be 2m tall. So your lighting will need to be 9m above the level of the ring, say 10m from the ground for sake of argument.

that's the one... that would be great if you could thank you Message sent.

Is this the remote? As Robin says above, the buttons aren't that reliable. Depending which one it is I might even have a spare one I'll send you.
