Title: Neve 500 series 1084 eq... pre orders.. CLOSED
Post by: peter purpose on November 01, 2009, 10:09:19 AM
Gents,
Before I spunk another 300 quid on something nobody wants.... any interest in a 500 series 1084?
I've dumped the hi and lo pass filters (no room on the board) and added a couple of extra frequencies in the high band.
Using a single VTB9050 inductor for the mid band.
Kindly express any interest here.

Sounds interesting!

Will these be like your other kits where it will have the metal and some other parts with it?

Yes... Pcbs, 500 series metalwork and probably the custom output transformer.

I'd be in for one or two depending on price.

is this going to be 51x or standard 500 format?

Probably standard, with a dc/dc converter.

I'm definitely in for two, but why not make it a double wide version and add the high and low pass filters? I've always wondered why no one has tackled a 1073 or 1084 500 series!

if it comes like a kit , as you stuff does
then one or two for me , thanks

Excellent! Yeah Il be in for 1 or 2 depending on price. I have always wanted to try a 500 series DIY  :)

Also, if you have two separate units, what is the accuracy like in regards to EQs when using them in stereo pairs even at the same settings?

I have never used two separate EQs as stereo unless they are a stereo EQ unit already so I am wondering whether they are as sensitive as using two separate mono compressors in stereo, do they have to match components somewhere for each EQ?

Thanks

Post by: substitute on November 01, 2009, 07:59:05 PM
Definitely interested, but for what it's worth I'd really prefer an option sans-metal work.  Even if other folks dig it, I think you'd sell more if it was just the pcb and the more esoteric parts.

The lovely Ed Anderson is having a pop at smallifying the LO1166, so that we can nail more than a few components to the board. I anticipate yummy iron.

Probably standard, with a dc/dc converter.
Please excuse my ignorance, but what is the difference between 500 and the 51x format? I might be interested in 8 modules if it can fit into the 51x frame.

Title: Re: 500 series Neve 1084 eq... any interest?
Post by: benlindell on November 03, 2009, 08:18:53 PM
The 51X has +/-24V using a couple of extra pins at the bottom. 51X is designed to be backwards compatible with 500 series modules as I recall so these will fit fine with your 51X frame.

I'm was tinkering with my own, non-500-type 1084 line eq for my own use, but would jump on a couple of these if the price is right.

Seems price is an issue with others who have posted in this thread too.  Do you, as of yet, have any rough ballpark on what this will cost the end user?

When isn't it in this place?

Carnhill input, custom output, big inductor, 3 Grayhill single deck rotaries and a bucket of other stuff.

This isn't going to be done on the cheap.

Seems daft not to........

51x compatible, but a snip and a file makes it standard.
Means you can leave out the dc-dc converter and associated gubbins if a 51 boy.

I remember reading at a forum once that a high quality high and low pass filter unit would make a killing because theres none available. iangomes, if you built a kit, I reckon it will do well. I have no idea how difficult it would be though to design and build?????

'Ullo, Peter . . .


   Count me in for a pair, - just don't tell the Missus . . . !


  As far as the HPF is concerned, it would be brilliant to be able to include it if at all possible. I find the HPF on Neve stuff to be very useful both to tape and in the mix. I find the LPF to be very useful too, but less so than the HPF. If you can't fit it in, I would still be very very happy without! Not a deal-breaker for me, but very welcome if at all possible.

Yeah...cause now there's a fourth switch added at the bottom. I'm guessing it's off...switch on...and through the different freq's?

EDIT: Hmm...actually, i'm thinking it's the top switch that's been added....that's the HPF.

2 things, what ever happened with Skylar's great CAD engineering work on the N style knobs? A small version would be stellar on this eq.  ;D

I believe this is the first official 500 series project to take advantage of the 24V option on the GDIY racks isn't it?? Kudos on that one Peter!  8)

I believe this is the first official 500 series project to take advantage of the 24V option on the GDIY racks isn't it?? Kudos on that one Peter!  8)

Cheers, Jeff
Will this unit still work on my API 600b lunchbox?

Where do you get those white rectangle switches that the Neve has?

since Peter is a clever boy he incl. a DC/DC converter for "the other Alliance":
51x compatible, but a snip and a file makes it standard.
Means you can leave out the dc-dc converter and associated gubbins if a 51 boy.

Check out the api site

http://www.apiaudio.com/b500vpr.html

It appears that theres +16  -16  and 48 volt supplys.  At least coming out of the PSU.

I might have the same problem but of course we should probably be building the diy vpr rack.

I'm not going to order the new type before I've nailed the converter ramp up circuitry. I need to get this spot on before I spunk any more wedge.

2: a company that produce plastic objects (hot liquid plastic injection ...)

The current limiting will depend on the output amplifier.

In the 1073/1272 style amp it draws a good thwack when powering
up, then stabilizes at the 70-80mA bias point.

I don't know what these will do, it'd be worth checking a functioning
circuit.

But, by holding off until the rack supply is stable I don't have any problems
even with a rack full of MP-500NV's.
Title: Re: 500 series Neve 1084 eq... now with extra 51X..!!
Post by: edanderson on November 11, 2009, 03:18:42 PM
dan's circuit uses a DC-DC converter.  the transistor (mostly likely the one in the photo, near the silver DC-DC block) probably has a timing cap that keeps it from "turning on" the DC-DC converter until the cap has filled, which delays the turn-on.  i interpret dan's post to mean that there actually isn't any current limiting per se, just a delay that allows the rack power supply to stabilize before it is hit by the turn on surge from his module.

keep in mind that dan's module is a 2 space unit, so even if the module draws quite a bit, a rack full of modules is still only "half full" as far as the current per slot spec is concerned.  another point of comparison might be avedis' MA5, which crams the neve type class A circuit into a single slot.  that module has some issues with the current spike on power on in some racks, at least it says something to that effect on his site.  also, colin of audiomaintenance fame has done a neve type in a single space, and i think he uses an onboard linear regulator- no idea if it has a gradual turnon or not.

Hi,

How about a LM317, connected as a current source of 100mA, that way the whole circuit never draws more as 100mA together with the DC DC converter you also have a low voltage super reg. This way I don't think you need switch on delay, and on circuit fault the whole thing never draws more current as 100mA. Maybe for dynamic purpose you can increase it to a 150mA.

Design by committee is a term referring to a style of design and its resultant output when a group of entities comes together to produce something (often the design of technological systems or standards), particularly in the presence of poor and incompetent leadership. The defining characteristics of "design by committee" are needless complexity, internal inconsistency, logical flaws, banality, and the lack of a unifying vision.

Hi,

I checked the data sheet of the TDK CC6-2412DF-E, but that needs minimum 18V, and you have 15V I don't think that one will work, and instead of 0-24V you get +/-/ground 12V ofcourse you can use it but you don't need the 450mA, these give a bigger inrush as well because of the larger coil inside.

And the current control has nothing to do with the DC DC convertor.

Hi,

It's being used with both the +16V and -16V rails (32V).

And as it's an isolated DC-DC converter, you can ground the -Vout and have 24V on the +V out. Leaving COM unconnected.

Post by: djn111 on November 13, 2009, 01:47:04 PM
Hi, that i understand but why the switching on delay, if you have more in one rack, you have to make the delay variable otherwise they switch on together/close anyway.

Or is to wait for the other modules to power on and after that the 1084 swithes on.

So I think the inrusch limiting for the DCDC converter is still neccecary.

And if you use the 32V (16+16V floating) and the earth connection are split as far as I know, and all transformers on the in and out, why use it at all?

DJN

Title: Re: 500 series Neve 1084 eq... now with extra 51X..!!
Post by: edanderson on November 13, 2009, 03:26:48 PM
okay so if you have more than one in a rack, and the delay should be variable, how do you accomplish that reliably?

yes, in this case the idea is that these modules will "wait" to come on until the power supply in the rack has stabilized.  this is needed due to the power supply's inherent turn-on behavior AND that you can't count on the other, different modules to have well behaved turn-on behavior.

if you limit the inrush current to the DCDC converter, it may not be happy.  what do we know about this device's behavior when demand outstrips supply?  

the circuit was designed for 24V.  32V might work, but it is a 30% increase, so it would be worthwhile to take a look at the circuit itself and see if any changes (due device ratings or biasing concerns) need to be made.  and if changes are needed, since we're after the exact performance of the original circuit, that may be an argument for some kind of regulation to bring the voltage down to ~24V.  linear or switching, both have their advantages and disadvantages.

peter - any thoughts on plating both sides of the edge finger? the doubled up connections make me feel warm and fuzzy... but perhaps you don't think it's necessary?

years ago, the first time i encountered a lunchbox in a studio, the owner had to re-seat the modules multiple times during the session, lots of intermittent problems.. ergh. perhaps that particular lunchbox was from the wrong side of the tracks... but i wasn't too impressed with these edge connectors at the time :-\

but these day's i've caved in to the 500 series like everyone else... haha

you've done such a beautiful job with the layout, if you nail the front panel design i think you'll have MUCH interest, even from the non-diy world. as far as i know there's nothing quite like it out there.

BTW: dan - great work on the harrison module - i bet the layout is pretty tight for that front panel board!

haima,

some api consoles use the top side pins for other functions, so it is a problem to have pads on both sides of the PCB.  this is why currently manufactured api modules only have bottom side pads.  most racks bridge top and bottom, so it could be more reliable as you suggest, but then you might plug it into a console and it doesn't work...

there are some 500 series modules that plate both sides (JLM... others?) i guess they aren't compatible with some consoles frames...

ed
Yes Ed. The 200 series also uses the top side gold fingers for side chain signal normals, DC control signals and so on. Quite clever IMHO!

I don't think that the API VPR spec specifies which side the gold finger should be on. I agree though. Should be the PCB bottom.
Title: Re: 500 series Neve 1084 eq... prototype two ready for testing
Post by: Dan Kennedy on December 10, 2009, 08:17:11 PM
I'm in the both camp. I've had to work with those fukkin edge connectors
since the '70's in lot's of different but similar racked equipment.

The connectors, especially frequently accessed ones get "soft" and prone
to dirt and iffy connections. With two sides your chances are better.

Haima, the Harrison is spacious compared to Peter's layout. Old age and
laziness setting in...

Actually, since Peter's 1084 eq's are mainly heading for the 51x racks, either side or both will be fine. Our edge connectors are 18 positions and dual sided so 36 pins to be exact. Volker has tied both of the pins together with PCB tracks so why not put gold fingers on both sides. It will be a little more money but might be well spent.
Title: Re: 500 series Neve 1084 eq... prototype two ready for testing

Thanks for the praise boys. Nice to know the thing at least looks good. Bollox to how it sounds as long as it looks right eh..!!
No problem doubling up the connectors.
You don't mind if I leave out unused pins? The price of gold is astronomical.

Post by: haima on December 10, 2009, 10:41:39 PM
i guess the 1% of users who might want to put these in a incompatible console can just scratch the top pads off (& cash in the gold!). the rest of us can potentially gain more reliability.

i say skip the unused pins for sure.

Added 20k and 25k to the high band.
Mid band with 9050 inductor is slightly different in the higher two frequencies 7k2/6k9 10k/9k. These could be fiddled with using TK's suggested 9052, or cap swapping.
Low band is standard, as is HPF.

Post by: Tekay on December 12, 2009, 04:07:58 AM
Using the vtb9050, the 7k2 will be right with the 2n2 cap, the original 200mH/2n2 gives 7k59, toget that with the vtb9050, change 2n2 to two 1n in parallel. For the 10k position change 1n2 to a 1n in parallel with a 100p.
I started to work on a similare unit two years ago using consentric switches/pot like an API550A, but i have had to much work to do so it may never be finished.

Probably standard, with a dc/dc converter.

It is now 51x compatible and I assume you would only use the dc-dc converter if you needed it to be compatible with standard racks.

Hi Guys,

    SO I am lucky enough to have Peter's prototype here in my rack! Ner-ni-ner-ner! It has to be said that it has not got the right output transformer yet. I believe this is coming form Ed Anderson. My immediate impression is that it is going to be stunning! At the moment. it won't handle too much level, thanks to the output tranny, and it is rather warmer in sound than I might expect! My every instinct tells me that this is due to the transformer, and not anything else, and I am waiting eagerly for the real tranny which should be like the LO-whateverthenumber.


    In the words of MikoKensington - "It's time to carve sh*t up!" and carve it up it does! Top end with the extra frequencies is absolutely to die for. Rupert's never did this! Guess it wasn't called for for am or fm broadcasting . . . 'kin' essential for me. A nice touch Peter, and seriously usable. The extra frequencies you chose seem spot on to me. Logical progression up the frequency band to my ears at least.

   Hi-q seriously carves sh*t up!. properlike, and everyfink. Hi pass smooth as a Cashmire COdpiece, and da bass goes "Boof"! Very warm bass, and not much headrooom(at the 'mo,), but fat as you like.

   As soon as output tranny is updated, I have arranged to compare it with some original 1073's, with which it shares almost exactly the same circuit, only difference being the HF switching, and some extra frequencies in the mid, I believe. No low pass, just like this one. That'll be the real test of authenticity, but for now rest assured that it sounds great already like this, headroom notwithstanding.

   It is definitely a squeeze having so much knobbage on the front panel. In practice, you have to switch frequencies one click at a time, not in a big sweep. The pots he has chosen are fairly stiff in action, and well nigh impossible to accidentally knock. I would be unlikely to set a gain amount absolutely before changing frequency anyway. With real estate in such short supply, there has to be some give somewhere, and in practice I am sure it won't be a problem for me. (I am a southpaw, and it pleases me no end that for ONCE something is slightly easier for me than all you righty's! Ha!).




     I'll keep you all abreast of my findings.



        Kindest Merry Bah Humbug To You All!

Hi,


    so, at the end of the day, I am in LURV . . . Baby, dis is da lick! Even with the slightly reduced Headroom or Output transformer saturation. I tried it all over the mix. Kit(m part of ms), bass, kick sn. Kinda hard without freaking with my levels too much, 'cos it hasn't got the headroom with this output tranny, but pretty much what the doctor ordered everywhere. Then I got a vocal sound in 2 mins flat from a standing start. Uphill. And I have been trying to better it all day. None of the usual suspects come close. API 550a just sounds so nasty - clack-y, even!. Now in the past, I have not often reached for Neve for vocals. Even with the Class AB1 stuff(1081, 33114, 3114 etc) with the switchable top end, they just don't go high enough for that "air". And, I have only used a 1084 as a mic-amp before. 1066 or 1073 tends to be just too hard for me in the mix with 10 or 12kHz at the top end. Well, I am happy to report that you can avoid that characteristic harshness with this baby! Dial it up, and wind it in! 20-25kHz is the shizzle . . .

     _ "Time-to-carve-sh*t-up" is upon us, judgment day is here, and woe betide me if i can't get a rack full of these puppies. - 'kin' QUICK! - It feels a bit like shooting fish in a barrel.

Why are you converting DC?
Because plus and minus 16v is nfg for this circuit.

Yes, thanks, I know, to make it 51x rack compatible.  But how bout those of us with a 24v supply?  Is it easy enough to omit the shiny box and run it old fashioned on 24v tip to tail?

(I believe Plumsolly was also asking about this on bottom of page 11.)

Post by: plumsolly on December 26, 2009, 01:12:00 AM
Tommypiper: This is my understanding: It is 51x compatible without the dc-dc converter, because the 51x racks have 24v. The dc-dc converter would be used only if one needed to make it compatible with standard racks. With a 24v supply you can leave out the dc-dc converter just like you would when plugging into a 51x rack.

Regarding output iron, are you aware of the new Lundahl based on the LO1166?  http://www.lundahl.se/pdfs/datash/2734.pdf  It could be soldered right onto your board, if it fits.  Would have plenty headroom.

Just heard back from Tim.  He has them manufactured, and won't sell them.  Apparently they are part of a kit or something.  

So, an odd part to be sourced for your PCB...  It's probly easy enough to DIY them from copper or tin  sheet... :)

No. The holes in the pcb line up with the screws in the Carnhill casing.

I wasn't, but am now. Still too big anyway.

I see you used a marinair traffo there.  Do you happen to know whether the marinair screws line up the same with a carnhill?  Also is it the same size physically or bigger than a Carnhill?

PCB set (mainboard & amp boards)
500 series metalwork
mounting hardware
2 toggle switches
Heatsink
Sockets & pins for the amps
P&P included

That lot will set you back 135GBP per channel, plus 4% paypal fees.

Hi,

Some (hopefully not stupid) questions:

1) Is there a BOM available?
2) Are the inductors, trannies or grayhills custom jobs?
3) Do the rockers replace the toggles as seen in the photos?
4) Does the 500 metalwork include the front panel?
5) Does P&P mean postage/shipping?
6) Is this my last question?  :P

Thanks!

Paid for a EQN 1084 kit.

I am not familiar with this build process, so if anyone have any BOM list for this build that I can use as a foundation for my build would be great.  :) Like with reference to part numbers or suppliers, etc.

I would also like to know what parts people are using to produce the results they are getting with their EQ build so that it will help me decide what parts to purchase.

Has all issues in regards to the low headroom or any bugs been sorted out?

Thanks
