Efficiency and sensitivity conversion - loudspeaker ...
http://www.sengpielaudio.com/calculator-efficiency.htm
Loudspeaker efficiency versus sensitivity Loudspeaker efficiency and loudspeaker sensitivity level are not the same. Conversion of sensitivity level in dB per 1 watt and a distance of 1 meter to energy efficiency in percent for passive loudspeakers For an 8 ohm loudspeaker, the voltage of 2.83 volts produces exactly 1 watt.

Sound intensity I = p eff 2 / Z 0 in W/m 2 = P ac / Ain W/m 2 Perfused area A = 4 × π × r 2 in m 2 Distance measurement point from the sound source r in meters (has only meaning with sound pressure, not with sound power) Acoustic impedance of air Z 0 = 413 N·s/m 3 at 20 °C Sound pressure p eff in Pa = N/m 2 In point-like sound sources ...

http://www.sengpielaudio.com/calculator-gainloss.htm
Amplifier Conversion - Gain / Loss Gain means signal strength or amplification.In audio we use only voltage amplification. Forget the power. The amplification factor, also called gain, is the extent to which an active device boosts the strength of a signal.
Voltage current resistance and electric power general ...
http://www.sengpielaudio.com/calculator-ohm.htm
The nominal impedance Z = 4, 8, and 16 ohms (loudspeakers) is often assumed as resistance R. Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

Use ADI-2 as a DAC only (Page 1) - RME User Forum
https://www.forum.rme-audio.de/viewtopic.php?id=30931
So if you would own the ADI-2 Pro FS R BE, then you could use the following settings with auto ref level enabled: DAC Volume: -6. By "auto ref level" feature the a Ref Level of +19 dBu would automatically be chose, you see it on the front display. and finally you should achieve then a SNR of 119dB at the ADI-2 Pro FS R BE.
