Yup, it's not what it does with the 5.1 toggle switch set to ON, but what it does when it's set to OFF that's the problem in the design.

It should have gone to a direct to volume control mode and then out the other end.

Besides a potential problem with double bass (due to the LFE channel being blended with all the bass below 80 Hz from the other 5 channels, besides the 5 main speakers getting full frequency information) on 5.1 material, it poses an even greater problem with those DVD-Audio and SACD discs that are mixed with either a full range "heads up, voice of God" channel instead of an LFE channel, or the new way of mixing with no center channel and no LFE channel where those two are routed for use as stereo side channels.

You see the problem with the way the OFF setting on the 5.1 analog input toggle switch is implemented now?

Another BIG reason why OFF should have meant exactly that.
