SP3 tape loop

Hi--Does either tape recording loop on the SP3 include the subwoofer signal? I want to insert an equalizer in the loop that will control both front main channels and the subwoofer. Is this possible?

And, will it work for all inputs?

Yes, it is an entire analog signal from the currently selected input, with no processing. Note that it does not rely back the DVR and TAPE input signals themselves, when selected.

P.S.

However, it would not include 7.1 analog inputs when selected, other than the L and R.
