    Load limit curve (amplifier voltage and current vs load impedance)

    With this thread I would like to introduce an amplifier measurement that has been popularised by F. Montanucci on the Italian magazine AudioReview (and previously, I believe, on Suono). It is defined as "caratteristica di carico limite" (CCL) that could be translated as "limit load...

    Understanding my soundcard loopback measurements

    Hi all. I am having some learning time testing my good old E-MU 0404 soundcard in loopback. The card as combined inputs: - TRS, Zin = 1 MOhm, FS = 12 dBV FS (~ 4 Vrms) - XLR, Zin = 1.5 kOhm FS = 6 dBV FS (~ 2 Vrms) When using a TRS to RCA adapter, output is measured at 2,07 Vrms with my...
