Xover (Crossover)
The crossover splits the audio signal into 4 independent bands to enable optimum processing for the bass (L),
midrange (M), presence (P) and treble (H) frequency ranges. There are two four-band processing stages that share
the same crossover. The crossover points are 180Hz, 1kHz and 3.3kHz plus 6.5kHz for the optional 5
th limiter band.
The first stage is the 4-Band AGC (Automatic Gain Control) stage. This stage operates on the average level, letting
faster peaks through to the following limiter stage. It dynamically equalizes the program material to add consistency
while gently building up density to keep the following peak limiter stages from working too hard. The output of
each of the 4-Band AGC bands directly feed their corresponding peak limiter stage. The 4-Band Limiter stage
operates on the peak levels of the program material with each band optimized for its frequency range, controlling
peak levels for the following Sensus
 and Final Limiter stages.
Low Drive
Adjusts the amount of gain reduction in the Low Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Mid Drive
Adjusts the amount of gain reduction in the Mid Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Pres Drive
Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result in more
drive and because of the increased compression, a more consistent output from the band.
Hi Drive
Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
OV AGC Drv (Overall Multiband AGC Drive)
Adjusts the overall amount of drive to all four bands of the 4-Band AGC section simultaneously
over a + / - 6 dB range. Higher settings will increase the overall amount of compression and the
“dynamic EQ” effect of the 4-Band AGC. This can make the program material sound more
consistent. Be careful though because too much compression can cause the program material to
sound less natural and cause low-level noise in the program material to be brought up.
OV Lim Drv (Overall Limiter Drive)
Adjusts the overall amount of drive to all four bands of the multiband Limiter section
simultaneously over a + / - 6 dB range. Higher settings will increase density. This can increase
loudness but be careful because too much gain reduction in the limiters can lead to a “wall of
sound” effect that can cause the program material to sound “smashed”. This can also cause
additional artifacts to be generated in the following codec. Lower settings will reduce the density,
providing a more “open”, natural and dynamic sound.
