Sound Mode
Touching the Sound Mode Selector brings up the input
selection page. Here you can control how the MUSE
processes the source signal.
Auto:
This is the default processing mode. In auto mode, the
MUSE automatically decodes, up-mixes or down-mixes the
source signal* according to the source signal type and the
current loudspeaker layout. The result is that native dolby and
dts signals are decoded natively and all loudspeakers in the
room are utilized regardless of input signal format changes.
Two-channel analog sources are up-mixed according to the
room layout. Multi-channel and/or object-based digital signals
from HDMI or other digital inputs are up-mixed or down-mixed
according to the loudspeaker layout.
Direct:
This processing mode is available for any input signal
source. For most loudspeaker layouts equal to or larger than
5.1, direct mode reproduces audio or video content utilizing the
same speaker layout as the source signal was originally
recorded in. Analog signals are passed through from any 2-
channel input without any subsequent processing. Digital multi-
channel signals (such as 5.1 or 7.1) are passed through to the
appropriate loudspeakers according to the source format. Note
that loudspeakers not used in the source signal format (for
example, overhead loudspeakers in a 7.1 movie) will not
playback. Note also that missing loudspeaker signals due to
room layout limitations (for example, rear surround speakers in
a 7.1 movie being played in a 5.1 speaker layout) will not
playback.

Acurus MUSE Immersive Processor USER GUIDE
Stereo:
This mode is available for any input signal source.
Stereo allows the MUSE to play audio or video media in a
basic left-right (2-channel stereo) format. Multi-channel audio
is automatically down-mixed to 2-channels. Any other
loudspeakers present in the room other than the main left and
right speakers are not driven.
analog:
This mode is available for any analog stereo (2-
channel) input. Analog mode bypasses any digital processing
for utilizing the MUSE as a pure 2-channel pre-amplifier. This
mode is ideal for 2-channel or multi-channel critical listening
with large, high-performance loudspeakers.
party:
This mode is available for all inputs. Party is a variation
of auto mode in which any signal is up-mixed or down-mixed to
2.1 channels. The resulting left and right loudspeaker signals
are then routed to all available left and right loudspeakers
including surrounds and overhead speakers. This mode is
ideal for providing party music to fill a room with sound.
night:
This mode available for all inputs. Night is a variation of
auto mode in which dynamic compression is applied to the
signal to reduce its loudness. In addition, the subwoofer signal
is automatically attenuated. The result is an overall quieter
signal for listening at night without disturbing other members of
the household.
