| Re: Frequency response of AVRs?
Using REW, the soundcard is connected to the left and right analog CD input on the AVR, sub out to the BFD.
It makes no difference if the AVR is set to stereo (bass management) or direct (no BM).
When I measure the sub only I disconnect the soundcard input from the AVR and connect it to the BFD, so the only difference between the two measurement is the addition of the 3803 into the signal chain.
I use an ECM800 mic to take the meausement. With the 3803 in the loop it always rollsoff at 15hz, when I bypass the 3803 it extends to 10hz.
Hakka.
