reduction in the lower AGC bands and may cause muddiness with certain program
material. A little goes a long way.
Warmth
This Warm Bass EQ is a shelf boost at 150 Hz. Warmth EQ compensates for program
material that is naturally lacking in upper-bass fullness. Be judicious about applying too
much, as the resonant frequency of many automobile interiors lies in this frequency
range! Also, too much can cause excessive gain reduction in the following 4-Band AGC
stage. A little can give a nice, subtle warmth enhancement to voices and other program
material that may otherwise sound too thin.

Xover (Crossover)
The crossover splits the audio signal into 4 independent AGC bands to enable optimum processing
for the bass (L), midrange (M), presence (P) and treble (H) frequency ranges. The 4-Band AGC
and Multi-Band Limiter stages share the same crossover. The crossover points are 180Hz, 1kHz
and 3.3kHz and 6.5kHz for the 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 Multi-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 pre-emphasis and clipper 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.
