In the configurator of my D220 Expert Pro one could adjust the voltage.
Audeze spec for LCD-2 is:
Impedanz 70 Ohm
minimum power 100 mW
recommended power 250 mW
Simple calculation Power= Voltage (V) **2/Impedanz *1000 [mW] gives:
V= 2,6V -> P= 100 mW
V= 4,0V -> P= 229 mW
So for my LCD-2 4V is the correct voltage in the Devialet configurator.
Is that correct?
Hi, Manfred, according to Ohm’s Law you did the right thing!

How this changes over the entire frequency range should be calculated differently!
