I have a dedicated, powered subwoofer that is connect and when listening to records I would like to add some bass to the speakers by using the powered subwoofer in addition to my stereo speakers. My record player is connected to a phono pre-stage that is then connected to the Pioneer VSX-94 TXH either through CD input or CD-R/TAPE/MD. I am using the CD-R/TAPE input at the moment. I haven't been able to figure out how the Pioneer can include the Subwoofer to the current Stereo Output for CD-R/TAPE or CD. Any ideas?
