Here is my try to measure noise spectrum of Placid HD BP 2.1 in audio band. The the positive/negative rails were connected to audio input via electrolytic capacitor to remove DC offset. 5 figures: - positive rail unloaded (shunt eta. 150mV) - positive rail loaded by Legato (shunt eta. 100mV) - negative rail unloaded (shunt eta. 150mV) - negative rail loaded by Legato (shunt eta. 100mV) - Placid not powered The Y axis is calibrated. Notice: My Placid HD BP 2.1 has initial problem with negative voltage which I need to fix by changing a circuit a bit. More in the http://twistedpearaudio....d-at--2-8V----FIXED.aspx.
