That is simiar to what I am experiencing. Does the volumn level affect both the display and the processing of the Hughes unit?

I’m hoping that you guys might help me with an installation problem. After reading the input on this site, I recently purchased a Hughes AK-100. Although it came with the manuals, I still am not sure that it is connected correctly. I would like the Hughes to process all the various inputs, phono, FM, cassette, etc, in my system. Therefore I installed it after my preamp which is passive, and does not have a tape monitor in/out feature. I used the Hughes Hook Up Guide “input selector box”installation diagram, substituting the preamp as the “input selector box”. In this configuration, the display lights rarely light and then do so faintly. The sound output is also dramatically reduced. Now, when I actually plug the Hughes into my Niles auxiliary input selector, the display seems to operate normally and the sound output is much higher. This configuration, means however that the Hughes does not process all the system inputs. What am I doing wrong and how can I correct this? Is this preamp not compatible with the recommended Hughes configurations? If so, is it also incompatible with the Carver C9?
