I am using mogami xlt interconnects. Are you also using canare (or something similar) inside the ampís chassis?

Van Damme starquad core in and out here.

Seems to have less capacitance than Canare starquad. Van Damme - Specifications - Tour Grade Classic XKE Starquad microphone cable

Some silver plated strands thrown in too.

Thank you for all of your condolences. I really appreciate it.

I'm getting back to something that resembles normal.

Tom

Tom,
I'm about to start populating the ISS board, but I cannot find the detailed component mapping in the ISS docs.

The Mouser project lists all the components but does not list where to mount them (R7, R7, etc..)

Am I missing something?

Thanks,

Daan

Another question is regarding the connection from the ISS to my 4 meanwell RPS-400-36 PSU's..

The ISS documentation states to either configure for 115v or 230v.

I am assuming this configuration has to do with connecting the ISS to transformers as they typically need the primary wired in series

If I omit the wire bridge for 230v, am I correct in assuming that the output of the ISS will have two 230 VAC outputs (J8 --> AC | 0 | 0 | AC)?

Or do I also need the bridge for 230VAC above J8 when using the Meanwell SMPS's?

Argh!! It looks like I forgot to include the BOM in the design doc. I'll fix that when I get home. I travel on July 3rd, so expect the doc to have been fixed by July 4th or 5th. Sorry for the omission.

Configure the board for your local mains voltage. Then hook the Mean Well supplies to the two AC terminals (terminal 1 and 4). I forget which is the live and which is neutral. You can easily trace the neutral on the board. If I recall correctly, terminal 4 (oval pad) is the Neutral and terminal 1 (rectangular pad) is the Live.

I should add that to the doc as well.

Tom
