Racking a Studer 928 Channels

[smilan]

Hi,
I would like to rack two Studer 928 Channels.
I'm thinking of using this PSU:
https://www.jlmaudio.com/shop/power-plant-kit.html?display_tax_prices=1
Now I have few questions:
1. Can I connect the 0V to pins 11 and 11A, +16v to pins 3 and 4, - 16V to pins 1 and 2 and the phantom (+48V) to to pins 29 and 29A (all ta CN2) and expect the circuit to work?
2. 48Vs means the 0V reference for the +48V?
3. Can I keep the 5V (pins 12 and 12A on CN2) disconnected or the 5V is crucial for the circuit to work?
4. Is it possible to find a 64 pins connector with solder lugs?
Or it would be easier to solder the voltages and signal wires directly to the PCB?

1. Can I connect the 0V to pins 11 and 11A, +16v to pins 3 and 4, - 16V to pins 1 and 2 and the phantom (+48V) to to pins 29 and 29A (all ta CN2) and expect the circuit to work?

I think pin 11 and 11A on conncetor 1 are for the 0V reference of the 5V supplie, which should be a different PSU and isolated from the +-16V and +48V PSU. At least it was like that in the 900 series if I remember correclty

2. 48Vs means the 0V reference for the +48V?

I really don't know, hard to tell. Better to check the proper schematic for the 48V circuit.
I would think the 0v reference for the 48v would be the same as the one used for the +-16V

3. Can I keep the 5V (pins 12 and 12A on CN2) disconnected or the 5V is crucial for the circuit to work?

I think you need the 5V circuit, but it's pretty easy to test it out with and without the 5V supply.

4. Is it possible to find a 64 pins connector with solder lugs?

I think those connectors used by Studer are still being made and easy to find on the web.
There's threads here in groupdiy about it

Or it would be easier to solder the voltages and signal wires directly to the PCB?

More elegant to have the proper connector, dont you think so?

Thank you Whoops, I guess it will be more simple to use a 4 rails PSU for this project and supply a 5v to the circuit.
As far as the connector, this is the one I should be looking for?

I don't personally know, but do a search around here on studer connectors, I remember someone replied to me at some point with the studer connectors I needed.

I think those are 64-pin DIN 41612 “eurocard” connector

Hello

I think those are 64-pin DIN 41612 “eurocard” connector

Yes, studer mainly use 41612 since the 80', but can't be sure for this rebranded soundcraft.
Schemo show row A and C, its probably a 96pin (3row) without pins at middle row ?

Best
