SDI is not HDCP compliant as it does not and can not carry the encrypted signal. The Decimator may well allow the Mac to output non-protected content, but if you try and play HDCP protected content it will not pass.

I think he means that it acts as an HDCP-compliant "sink" device, so protected contect will still be output, and it then converts that to SDI effectively stripping off the HDCP.

 

 

That was my belief yes. However having done some fiddling this evening, Decimator on the output of a current model macbook pro works great, up until you try to play netflix, which doesn't work in safari, but does work in chrome. Works fine direct to monitor in both.

I believe that the Decimator MD-HX "Fixes" the HDCP issue on it's SDI outputs, by being HDCP compliant. I need to thoroughly test it one day, but I can say I've never had any issues.

 

It also has a tidy 4 SDI outputs!

 

In terms of resolution, 95% of modern equipment is 1920*1080, and that is an acceptable SDI resolution. I've had to deal with broken DVI connectors when running standard resolutions way more than I've had to deal with trying to run non standard res over SDI....

For what you describe, I'd use SDI. The blackmagic micro converters are good enough, and cheap enough that carrying a couple of spares isn't arduous. The SDI input to HDMI output have an SDI loop out, so you can link on a bunch of Screens if needed. They are USB powered, and typically are quite happy powered off the USB port on the back of the TV that they're feeding.

 

HDMI fibre is another way of doing it, but they can also be quite finicky and are really quite expensive!

 

If going down the SDI route, It's worth looking into the cost of pre made cables vs buying bulk reels and the right tools. We make all of our SDI now as it's a surprisingly quick job and a lot of the stuff we want is custom lengths. It's also very convenient just having a drum on the shelf and being able to turn it into a couple of 1m, 5m or just a 30m!

The young person's perspective is now not a feature of the Blue Room, sadly. If there are voices here, they perhaps feel unwilling to speak up but to be honest most of them aren't here. A lot of BR type discussion goes on elsewhere these days as a forum like this is not their platform.

 

We're just too busy overworking and raking in all the cash

Not being all that familiar with the requirements, would something like a picoscope be suitable?

I'd say if you know your kit wont cover it, then you'd be best served speaking to a PA hire firm, telling them what you need to achieve and I'm sure they'd be happy to work with you to build a kit list.

Kind of relevant to this discussion, my preferred multi-system method these days is a stream deck and companion!

Yeah in that case someone like lintec or radio structures should be able to make something suited to the need. Might even see a boost in performance, those sennheiser antennas are very convenient I know, but they're also very very wideband. If everything is in the same frequency range it's not the most efficient system.

What fails? The antennas themselves or the connections? If just the connections, self amalgating tape may be your friend!

I'm admittedly quite new to the game, but I've just been using xero since day one. The small fee is easily worth it for the convenience of reporting and being able to just hand a login to an accountant for end of year/checking.

David - I had a few bashes at my post as I found more info - 5.5x2.1 should be right from what I can find.

 

Bit late to the party, but couldn't find the PSU for my IEM transmitter the other day, and can confirm that the "standard" 5.5*2.1mm DC jack works well.

 

The Black Magic "standard" 5.5*2.5mm, works less well

From a climber's perspective, I *love* using DMM gear. Most of what I own, except belay plate, is DMM. Well priced, top quality, and made in the UK. Still don't trust anything like the quicklock/locksafe type gates though, too fiddly, and/or easy to unlock automatically. Screwgates for me thanks.

I did try when the topic first appeared on climbing sites.

I did look to see if anyone had posted, but clearly not closely enough. Apologies for any perceived thunder-stealing. At least we've flagged it up.

No problems, just glad that it got noticed this time, quite a serious problem...

 

 

I doubt DMM kit will comform to the required EN standards for industrial usage ! !
