I agree. I A/B'd a compex 760RS with Sowters with the unbalanced. I preferred the unbalanced on drums and mixbus. I actually took the Sowters out. I had my tech do a transparent electronic balanced input so that it would play nice with others.

And yes you need like an audio precision rig to cal it.

My feelings exactly. I did the exact same thing with mine. With all the transformers in my console and all my main outboard pieces my Compex didn't need the extra iron... especially for use on the mix bus situation. I had my 3 mono compexes completely overhauled and brought to factory spec recently and they are my new favourites. The 1176's aren't getting used as much lately.

Dear Dave,
Could you let me know which ADR Gear you refer to, related to your question, as we have discussed The Scamp, The Compex and the Vocal Stressor, then I am sure I can be of some help

Dear Dave-2
Sorry I think your question has been answered, I should have noticed that we have moved on to Page-2
Funny how some do not like the transformer balanced Ins/Outs, I linked mine out as well, Dick Swettenham preferred the Early Helios Lustraphone Type-69's without balancing with TX, so when DS and I re-launched Helios Electronics Ltd, we both agreed that the reissue of the Type-69 would not have any transformers on the Ins/Outs.
We do have balanced Ins/Out on our 500 Series Reissue, but this has been done electronically


Thanks for Posting

Best Regards,

Okay, bringing this one back

Does ANYONE have a manual for the ADR express limiter? There are about 1000 trim pots and switches inside this thing and I"m tired of just turning them randomly

Hello from germany,

my english is very bad, sorry for all times!

Here is my new project. I'm very glad to own the parts of my dreams for my ultimative outboard channel rack. Normally I work on DAW and this will become a multi purpose unit.

You can see the following modules:

Rack
2 EQ E900-N
1 Compex Limiter F760X-N
1 Selective Limiter E560-N

My questions:
Does anybody know something about the Deesser (E560-N)? I cannot find information.
I should recap the modules, but whats about later reselling. What do collectors say to recaped ore otherwise modified units?

Thanks to all of for all the information I have found the last days here. I will do my part also, because I am a electronic professional for more than 25 years specialised in IT and analog semiconductor cirtuits.

Woah! Beauties.

I just want to say thanks to Arny at Helios for sending me the Express Limiter manual I've been looking for for a century!

Dear Ralf,
Most engineers re-cap, but often this can be a mistake if you do not get the right ones, because some company’s stock today the specs are far more spread out.
In other words if it states 8µf its no good sticking in a 10µf, I have seen a 15µf replaced with a 25µf. the person has gone to his/her nearest Radio Shack type shop, in the UK = Maplins and the guy behind the count states
"Sorry Sir, but it is very difficult to get 15µf caps today take a 25µf, it will do fine"
Some of those should not even be allowed to empty a dustbin let alone advise and sell electronic components.

Later the DIY electronics engineer who has changed 15µf for 25µf is now comparing his original with our re-issue and because theirs now sounds different, they swear that our re-issue is wrong, be-it a Type-69, or a F760, because they will have also changed the none polarized for the nearest as suggested by the counter assistant.

I fully understand Ralf that you are a Fully Qualified Engineer, so therefore I respect that you will get it right,
My Post is for those who are not so qualified, it is in order to help them update and refurbish their equipment correctly.
Here is a LINK, Farnel’s
Aluminium Electrolytic | Farnell United Kingdom
I am told that Farnel are all over the world, although during my many enjoyable studio visits to Germany, I found some excellent stores selling electronic components, there is one in Munich that is totally out of this world, mind you that was 30 years ago

I will look into the 560N, but I would imagine it to be a single module of the Vocal Stressor, or something similar, but I could be wrong.

Best Regards

Arny,

do You have the correct manuals and sheets to the models above?

Do You know anything to the history of the rack itself ?

Thank You very much!

My plan: recap and calibrate of the modules, set them up in their original rack and use the not needed place for a pot and patch bay. I want to be able to switch between several applications of the rack like vocal stresser, NY-style, de-esser, notch, external trigger, side chain, sereral inserts etc.

Dear Ralf
Yes I do have the manuals, for the F760 and the 900, I will have to check out the 560 for you.
Please send your email details to me at:
[email protected]

and I will send them via "Pando" which is the safest way, as they are quite larges pdf files.

Sorry I don't recognise the Rack.

Best Regards

Tony.

Tony,
thank You very much! The documents You mailed are exactly what I need.


Only the infos to the E560 are missing jet. There are two PBB's inside, one labeled F600 tho oter E560.

I will plan the recap procedure and post the results.

Ralf

Have anybody more infos aubout the ADR gear? Maybe setup protocols?
