In this case the only way to adjust the relative values of the non-Front channels is via individual stream Level controls. This chip is specified as capable of operating at a Hz sample ratebut although this allows an input -3 dB frequency response limit of Hz, the output limit is only Hz Since auto-calibration uses a “loopback” cable from output to input, you will need a special RCA-to Line In Max sens 0.
