I have looked carefully at the rsp-1066 service manual posted here not long ago :
It appears the 1066 only has one stereo ADC, the AK 5351.
Considering that, either the bass addition for the multi-input is done in the analog domain (unlikely I think) or there's only bass addition for the main channels.
Currious also, there's no trace redirection to ADC, or any form of bass-management, for the multi-channel input in the schematics diagram, page 20 of service manual.
We are also missing pages 21 to 32 (mostly schematics) according to the Table of contents.
Maybe the answer is there ?
