OPTIMOD SURROUND PROCESSOR OPERATION
3-33
There is also a corresponding two-band preset called CLASSICAL-2B+AGC. Even
more transparent, “purist” classical processing is available from this preset, which is
phase-linear and which preserves the spectral balance of the original material as
much as possible. However, if you need a bit more automatic re-equalization than
the CLASSICAL
TWO-BAND preset provides, use the CLASSICAL 5-BAND preset.
CLASSICAL-2B
SFTKN (Classical using two-band Soft-Knee Compression) defeats
the AGC and exploits the 8685’s soft-knee two-band compression. Quiet material is
gently compressed with a very low compression ratio. The compression ratio in-
creases as the source material gets louder (see Figure 3-2
on page 3-54). Very quiet
material is typically amplified by 10 dB. This level-dependent compression ratio pro-
vides very smooth, subtle compression.
Because the CLASSICAL presets preserve a significant amount of the dynamic range
present in the source material (including speech), it is wise to use a separate micro-
phone processor to ensure appropriate voice/music balance.
EDGE: This preset is designed for hit music broadcasters who prefer extremely
punchy bass to fastidious distortion control. It is loud and has a bright high fre-
quency texture.
GOLD: GOLD is loud and “hi-fi”-sounding while still respecting the limitations and
