Full Version: Preamp output impedance

As some of you, I want to connect my dynamic headphones to the preamp out connectors. (I have sorted out my electrostatics already, but I would not want to use the energizer between the amp and the speakers). I have ordered the adaptor, but would like to know what is the output impedance of the RCA outputs - it does not appear anywhere in the literature.

Does any of you have that information? If it is too high, some headphones will not work properly.

I recently asked Devialet Support:

"Dear Devialet,

Can you tell me the output impedance of the pre-out of the Expert 400?

The reason I ask:

I'm driving headphones out of the pre-out jacks of my Expert 400. I want to make sure there is a good impedance match between my headphones and the pre-out."

Here is the reply:

"Thank you for your message.
The output impedance is less than 1 Ohm on expert and expert pro.
If you need to know for the trigger too: trigger out is indeed 12V, with current capability of approx 50mA

I wish you a good day,
