Controls (SPREAD, AREA)
The SPREAD input and AREA flag are used to con-
trol the FLOUT and FROUT signals in QSurround
mode. In QSurround mode, the total sound heard is
an enhanced version (virtual sound source) of the
actual sound sources (speaker). When SPREAD is
HIGH, the virtual sound source is widened, strength-
ening the surround enhancement effect. The AREA
flag is used to widen the surround sound effect
sweet-spot. This can be used for a larger listening
audience. Note that AREA is set by serial input data
only, and is therefore not available in parallel inter-
face mode. The SPREAD and AREA control func-
tions are shown in the following figure.
