Note:
When a subwoofer has been connected and the virtual surround function is being used, the signal played from the subwoofer channel is
LFE only (only when playing Dolby Digital or DTS signals) for initial factory settings (i.e., the setting of the front speaker is “LARGE” and
the setting of the subwoofer mode is “NORM”).
When subwoofer effects are felt to be weak, while in the system setup mode try setting the subwoofer mode to “+MAIN”, or the front
speaker to “SMALL” in the system setup “Speaker Configuration” settings.
Making these settings will result in the low-frequency sounds of the front channel being played from the subwoofer.
