4-12. Clipper
The rated output (actual maximum output) of a TV is measured when the combined distortion (THD+N) is at 10%. The
clipper function allows the user to clip the output amplitude freely, for example to get a rated output of 10W or 5W using an
amplifier with 15W output.
Clip Level
Set &h27[7] to “H” when using the clipper function.

Clipper function OFF
Clipper function ON
Operation Description
The clip level is configured at the upper 8 bits &h28[7:0] and lower 8 bits &h29[7:0].
Decreasing the configured value decreases the clip level.
Negative clip level configures the opposite data of positive clip level.
(Note) The clipper function must be used when DSP output is output to DF1, DF2 or DF3.
