Subwoofer
Sur. and Stereo
This mode is recommended if
the active subwoofer should
work with multi-channel
reproduction ( DSP Spatial,
Dolby Pro Logic, e.g.) and in
Pure Stereo operation.
Such a setting is particularly
beneficial if the other speakers
can produce bass tones, but
only within a limited range. Main
compact or shelf-mounted
speakers with limited bass
reproduction belong to this
category.
Subwoofer
Surround only
In this mode, the subwoofer is
only activated if a surround
sound such as
Movie,
Matrix, DSP Spatial e.g. is
selected.
In Pure Analog operation such
as Pure Analog, DSP Stereo or
Digital Stereo, the sub-
woofer remains silent.
This setting is ideal for the purist
listener who likes to experience
films and concerts on DVD with
all six channels, including the
subwoofer, but is happy to rely on
just the main speakers for normal
stereo operation such as CD or
Phono. This assumes, of course,
that both main speakers can
produce the required deep base
tones cleanly.
