Fader-start interface problem

Fair enuffski.

… so long as all your presenters are trained to know that if they drop the fader, the track drops out of the Playlist and has to be fished out of the Browser’s Recycle Bin (or whatever you right-click-rename it to: I do personally prefer Playlist History :wink: ) to be replayed later. :smiley:

(And to everyone smugly reading this and thinking ‘I’ve never dropped the fader on an on-air, playing track!’: I bet you will do it one day!)

Haha Cad.

Happened plenty of times in front of my eyes before! You can’t keep track of what your hands are doing, and before you know it…gone!!

Well…good news everyone…finally managed to get into the desk today, and it was easier than first though…3 screws underneath the faders on the top, 3 screws on the base of the desk, and one on either side, and then it just lifts up! Easier than first thought anyway!

Got inside to see lots of nice things, inlcuding dischargers we stayed well away from. Infact, other than first though that there is a master jumper, it is per fader, so we changed 4 faders we needed. Fairly easy, but yes, a long-nosed pair of plyers were needed!

So the moment of truth after putting every input back into the desk and putting it back in its wooden mount, opened up mAirList, and success! It works a charm! Just as needed, start, then stop when the fader is dropped.

All i can say guys, is a really big thank you! I wouldn’t have actually had a single clue without your expertise and help. I really appreciate it.

Thanks once again, Ryan.

I suspect that one of the plus’s of having the item “stopped/ejected” when you drop the fader is for live-assist usage when you have a bed running and you want to drop items in over the bed but don’t want to use the Cartwall (maybe you prefer fader-starts)… So when you hit the bed’s “tag”, you can drop the fader and the bed is removed and the fader is then free for the next item.

Hi Ryan, breath a sigh of relief and thanks for the info, its noted for future reference. Also handy knowing it can be changed per fader, surprising on a budget mixer.

Reading Ducos’ instructions again, although poorly described this could be what he meant. A blessing every fader button/knob did/does not have to be removed.

Still waiting for an answer from the engineer so I will just copy this info to him and thank him for his willingness to help.

Thanks again for the tip.

Kind regards Tony

Thanks Charlie and Tony.

I was surprised myself seeing that they are per fader after searching a while in the master section PCB boards. And yes i understand what Duco meant now…he was the person who responded to me to get into it, and with a bit of common sense of how everything should come apart, we eventually did it after taking out every input and working on it out of the studio!

Yes Charlie, that’s the way i prefer it having the item stop when the fader is dropped, ready immediately to bring up for the next item, which i find more versatile that way, plus it is what i’m used to at City haha!

Thanks again for your help, Ryan.

Ah, all is explained: you have all your Players feeding in to one fader, instead of a fader per Player. In that case, you’re right: you do need the ‘stop on drop.’

[FX: muttering in B/G ‘… typical cheap commercial station …’ ‘…not like a proper BBC desk …’ ‘… the old “one fader, one NEXT button, one brain cell” setup …’ >grumble< etc.] :wink:

PS: Yes I do appreciate that a D&R Airmate is not exactly overflowing with input channels! :smiley:

Ah no! Infact we have 3 players and a cartwall…each player is assigned to its own fader and also the cartwall is on one fader! Haha, maybe i am just weird in the way i like to have things work, but it’s what i am used to!

Had a nice fiddle today and it feels great…and feels right haha!

But yes, about the ‘ready to bring up for the next item’ was not meant in that way, but allows more versatility in the players used…e.g. with our 3 players, we can crossfade between 2 songs, with a sweeper inbetween e.g. player 1 (song)- assigned to fader 5 on our desk, player 2 (sweeper)- assigned to fader 6 on our desk, player 3 (song)- assigned to fader 7 on our desk. (fader 8 has cartwall and other audio such as the PC sound to use from youtube etc)

So that will allow to slowly fade player 1, play the sweeper while still fading, and slowly bring in player 3 with the song all at once!

Thanks, Ryan.

Well, whatever floats your boat, young 'un!

BTW I was reading both the D&R Airmate and Airmax manuals online today (aren’t Dutch translations into English utterly charming? :wink: ), and D&R themselves suggest the ‘pulse’ tally signal setting is preferable to ‘continuous’ for the majority of applications. ;D

I think that’s partly because most hardware kit nowadays uses ‘pulse start’ by default. Certainly the two START buttons on my Clyde Broadcast News mixer here each generate a single pulse across two pins of the associated 9-pin D connector when pressed; if you hold them down, they generate more pulses at ~two-second intervals. >shrug< Shame it’s a mono unit throughout, but it was a freebie; and it does have a dinky but pukka Sifam PPM on it! 8)

Haha. Yer, most things do come as pulse these days! But i suppose it doesn’t take to much to change the settings as we found out haha! :wink:

And yes the manual is rather amusing with the wording in some places! Speaking of PPM meters, we had one come with our package with the mixer from Preco, but we took it out of the wooden mount they already put it into and replaced it with a nice lighting up Denon CD Player 8)

Ryan.

You REMOVED the PPM?!! :o ???

[FX: wanders off muttering ‘PPMs good, LEDs bad; PPMs good, …’]

Haha, they just didn’t look the part, plus what’s the point when we have LED’s already on the desk?..they are there if needed anyway, along with our D&R Hybrid!

SIGH<

You kids … !

There is a reason why the BBC use PPMs even to this day, y’know! They wouldn’t shell out £75-plus per meter (much more for twin-needle units) if they could sensibly replace them with nice cheap LED stacks.

All (?) LED-stack meters share the same problem, which is an instantaneous fall time. Some instantaneous peaks, such as a particularly loud snare drum hit, can appear (and importantly, disappear) on the LED faster than you can see them.

This is fine in a live/PA situation because peaks don’t really ‘break’ anything and in any case you’re more concerned with sustained average levels. In broadcasting, peaks are the single most important thing to notice and manage. You may well be sending the signal down quite a long complex chain to the transmitter or control centre, and some equipment along the line may well be set to self-protect by cutting out on severe peaks, causing a brief (sometimes not so brief) dropout in signal.

So in broadcasting, missed peaks can be a disaster, and the BBC developed the PPM and its driver circuitry specifically to solve that problem. The time constant which applies a graceful slow fall time to a PPM needle means you never miss seeing any of those peaks, because the needle can’t instantaneously ‘switch off’’ like an LED stack does.

A PPM (a proper SUM one which shows the ‘total’ level of both stereo channels) means you never again have to try to add the left/right levels in your head; and also makes it Dead Simple to train new presenters. Peak speech at PPM 6 maximum, PPM 5 average; and peak music at PPM 5, PPM 4 average. That was how the BBC trained me to do it, anyhow. ;D None of that vague ‘well, keep speech into the yellow bits most of the time, and the music a few LED bars below that, mostly …’ that you get with LED stacks.

All that said, you will inevitably be using some kind of audio processor (Orban box or whatever) on your output, so some of this appears a bit arcane, quaint, and seemingly irrelevant nowadays; but it’s still best to TRY to ‘do it right’ in the studio, and you know, even after it’s been mangled by the audio processor, a genuinely well-mixed show still sounds better than one where the presenter is of the ‘turn everthing UP’ variety. :slight_smile:

PS: Since your PPMs are surplus to requirements, I’d be happy to send you the money to courier them to me here in Edinburgh; purely to save them cluttering up your storage space, you understand … :wink:

BFN

Very true!

We’ll keep the PPM’s for future use :smiley: haha

But regarding the LED’s, they do drop out of course, but the RED LIGHTS draw your attention to them quite a lot…also, there ARE LED meters that do have a slow drop out and NOT instantaneous, ala Logitek meters i have seen.

Thanks, Ryan.

How long do those red lights stay illuminated if you go over peak? Or did you mean the red LEDs in the stacks? We have presenters whose mission used to be to have everything ‘in the red LEDs’ all the time >SIGH< Now that we use a desk with PPMs and no LEDs anywhere, there is no ‘red’ to light up, therefore they behave MUCH better. :wink:

Agreed that a FEW (typically rather expensive) LED-stacks do now have a slow fall time :), but those are the exception and not the norm IME.

But my main point is that in radio, separate left-right meters are generally as useful as a chocolate teacup. What you need to know at all times is the TOTAL level. So try to do this quickly and in your head:
Left is reading -14dB and Right is reading -5dB: what’s the equivalent total MONO level in dB?

An indication that Left or Right has packed up or is way off balance is useful (that’s all I use those LED things for), which is why dual-needle PPMs exist: showing either SUM and DIFFERENCE (white and yellow needles, traditionally), or LEFT and RIGHT (green and red needles, traditionally). You should however be able to HEAR that e.g. Left has gone silent or the image is now 70% Right, so those types of PPMs are a luxury rather than an essential. The metering you absolutely need, and SHOULD be concentrating on, is your total SUMMED left+right level.

Disappointed to hear you won’t be sending me your ‘redundant’ PPMs :’( after all—I also can’t imagine how anyone as style-conscious as you (QUOTE: ‘they just didn’t look the part’) could conceive of any ‘future use’ for something as old and ‘un-cool’ as PPMs? :smiley:

Quality! haha! 8)

I shall give the PPMs a go one time when we have the money to buy a rack and put the CD Players elsewhere, because budget management are cheap like that :wink:
