Mastering monitor console

[Gold]

but does maselec use first order filter?

I would assume so but I don't know as I've never used one. He doesn't publish schematics. He would probably answer that question though. If you want to make one I'd go with single order. That's what everyone is used to. Probably the best combination of transparency and effectiveness at preventing excessive vertical modulation

The EE that was in a Neve mastering console I think had a fixed frequency crossover with choice of two slopes. My memory could be faulty. I've never seen one of those EE's in current use. I threw one away myself.

thats actually totally passive?

Yes. Only switching, and then an output attenuator for spk.

Unbalanced? How did you menage "pin 1 problem"  ?
What type of switches are used? Seiden?

This is incredible....!
I've been trying to piece together a console from old broadcast console bits and microcontrollers, can I have this instead?

Sure, all it takes is a ton of time and money.

Unbalanced?

Yes, as per request.

How did you menage "pin 1 problem"  ?

Only interfacing to transformer-balanced and GML8200 (which is unbalaned).

What type of switches are used? Seiden?

Yes I think so,  56-series iirc

Again, this is not my idea of "the best of all worlds" design - just an example of a client request.

I would probably have preferred to go with relays, balanced, and with MUCH cheaper switches/wires/connectors..

I'm interested what you use for your power supplies on your Shaker Desk Could you share that Gold?

I used Power One open frame linear supplies. There are two PSU units. Each PSU unit has four 3A bipolar 15vdc supplies. Two for Modulation and two for Preview. One of the PSU units has two bipolar 24vdc supplies. Each PSU has +12vdc and one of the two units has +5vdc.

Apologies if this is straying from the original topic -
Paul -
I recently purchased a few of the Kirkwood MS boards , my plan was just to insert an adjustable high pass to the difference channel, and make up the low end later on in the chain if required, do you think there will be issues with this approach?

That will work but i would suggest using his Widener board for this.  It is a more elegant solution. It is based on the crossover section of the Neumann VAB vertical amplitude limiter.

That board is a real sleeper. I kind of missed it when he designed it because it is similar to M/S. The possibilities that board open up are very different than the M/S board. I will be putting in some time to expand the capabilities of the widener. I expect it to be a very unique processor.

Thanks Paul, That sounds like a plan, there's plenty of other things I can use the MS boards for.

Do you remember the model numbers?

When I bought them I think they were branded they were Power One. I got them from Mouser and the SL Power/Condor looks like what I got. http://www.mouser.com/ProductDetail/Condor-SL-Power/HCC15-3-A+G/?qs=sGAEpiMZZMtl%252b%2ft8G5TWgLdn80A3nEGy%252biSwgOOGC%2fA%3d
