Another thing I found out is that the 7.1 inputs also lack sub output while set to Digital or the 80Hz analog crossover. I tested it out with an SACD. My player was set to all Large for the speakers and Sub was Yes, 1070 was still set to all Small and Sub Yes. Tried the 2CH Stereo and Multi CH SACD tracks as well as the normal CD layer. Could something be wrong with my 1070?
