Hi there, My implant: R-51PM + R-10SW (LFE RCA connection). Music source: Chromecast Audio (optical cable connection). Took me a lot of time to figure what I was doing but was really a pleasant adventure. Reading some forums I did: - Set subwoofer's Low Pass switch to LFE - Adjust subwoofer's Gain to the lowest level and raise slowly until it becomes audible (DYNAMIC BASS EQ: OFF) Sound seems very good but I still haven't figured: - How to decide between subwoofer's Phase (0° or 180°)? - SW connected, shall I close the Bass Reflex exists in the back of the R-51PMs? - When to use or not the Dynamic Bass EQ? - How to bypass several EQ sets when playlists are runing? Thanks in advance!
