There are several spatial effect modes available:
bit[3:0]
In Mode A (low byte = 00
hex
), the spatial effect depends on the source mode. If
the incoming signal is mono, Pseudo Stereo Effect is active; for stereo signals,
Pseudo Stereo Effect and Stereo Basewidth Enlargement is effective. The
strength of the effect is controllable by the upper byte. A negative value reduces
the stereo image. A strong spatial effect is recommended for small TV sets
where loudspeaker spacing is rather close. For large screen TV sets, a more
moderate spatial effect is recommended.
In Mode B, only Stereo Basewidth Enlargement is effective. For mono input sig-
nals, the Pseudo Stereo Effect has to be switched on.
It is worth mentioning that all spatial effects affect amplitude and phase
response. With the lower 4 bits, the frequency response can be customized. A
value of 0
hex
yields a flat response for center signals (L = R) but a high-pass
function for L or R only signals. A value of 6
hex
has a flat response for L or R
only signals but a low-pass function for center signals. By using 8
hex
, the fre-
quency response is automatically adapted to the sound material by choosing an
optimal high-pass gain.
