A/V-Receiver sound speaker levels - already compensated for loudspeaker sensivity?

Hi,

On most A/V receivers you can set the sound compensation level for each individual speaker (i.e. +/- X dB). But does the A/V receiver already compensate for the speaker's sensitivity? Because one speaker may have e.g. 86 dB sensitivity and another one 90 dB (1W@1M).

So does this mean that one should set the speakers with 86 dB to 0 dB compensation, and the ones with 90 dB to -4 dB compensation? Or will the A/V receiver already have compensated/normalized for that during the Audyssey (or similar) measurements, so that the sound level for each speaker should only be set to compensate based on listening position? I.e. if the listening position is closer to speaker A than B, the sound compensation level for speaker A should be set lower than for B?

Would anyone please care to explain?

Standardizing the acoustic output of the speakers attached to the AVR to match the dB markings on its volume control are one of the things that automated system optimization (Audyssey, MCACC, YPAO, etc.) do as part of their normal automated system adjustments. The setting of the internal trims is based, among other things on measurements made with the little calibration mic that comes with the AVR.

No, because the sound level at your listening location is dependent on other things than just speaker efficiency. This includes distance from the speaker to the listener, and the acoustics of the room.

Yes.

The automated adjustments are supposed to handle those differences automagically.

Ok, I see. Thanks for the clear explanation.

Is this valid even if you disable Audyssey, and use manual settings instead?
