Great that we can target our DAM DACs now to compare with 20k DACs...

p.s. A bit cheap that they didn't use the OEM boards indeed.

Anybody can do whatever they want, as long as it's a Soekris product :-), although I don't understand why they didn't use the dam1121 OEM board....

Maybe they should go even further and use this for their casing:

Crushed wood is stronger than steel

I'm trying to use a 1:1 transformer to connect a DAM to a nCORE 400. I get "static, noise hum" - low level, need to go up to speaker to hear it, and higher frequencies.

I just hooked it up floating using hot and cold leads. DAM in balanced mode / 1 channel per board.

May I hook up the the primary center-tap to ground on the DAM? Is there any DC level that could saturate my transformer?

In my enclosure, there is no Earth. This might be the problem maybe. No shielding. Is it impossible without a shielding box?

By Ground, do you mean the case/core?

From nCORE manual:

"You would never directly connect the cold pin of the input connector to the ground pin in the same way as you would never locally ground input of an isolation transformer because it would no longer provide isolation."

@soekris:


I do not need the output buffers of dac1321.


Is it possible to take the raw output from J8?


Thanks

J8 is the buffered audio, raw audio signals are available on TP1 and TP2, located at the end of the resistor networks.
