Chain is laptop to Topping E30 to SMSL HO200.
SMSL volume setting is MID.
Headphones used to set volume level is AKG K371.
First I play songs using headphones and determine a good volume level.
Next, at that volume level, I played 240hz tone and measured with multi meter.
Left channel measured at 0.09 V
Right channel measured at 0.094 V
I checked multiple times. Same results. I checked again using 60hz tone, again the channel difference stays at 0.004 V.
I use the first calculator at
to perform voltage to dB calculation.
db difference going from 0.09 to 0.094 is
~0.377db.
Is this a correct way to find channel difference in dB based on measured voltage difference?
Would this mean my headphones right side will be louder than left side by ~0.377 dB, as compare to using amp with no imbalance, when voltage match via left channel?
Thanks!
