Kompressor
Here is a brief explanation of each KOMPRESSOR setting.
Contour - This preset applies expansion below the threshold
point to provide a fuller sound at lower volume levels. Effect
decreases at higher volume levels. Nice effect for someone
wanting a fuller sound at low to moderate listening levels.
ATTACK - This preset applies expansion above the threshold
point to provide a nice quick punch or attack to the music.
Effect increase with higher volume levels. Like music with a
quick and punchy sound? Give this one a try.
Red-line - Provides a quick clamp to dynamic peaks while
still allowing a full sound to come through. Effect increases
at higher volume levels. Like to play it loud but want to
protect your speakers? Want low level details to come
through over road noise? Want a more even volume level to
your music? All can be achieved with this preset.
OFF - Pretty much says it all. This turns the KOMPRESSOR
off. This is the factory default setting.
After selecting your KOMPRESSOR setting you can adjust its
effect using the KOMPRESSOR ADJUSTMENT (
KOMP ADJ.)
setting located in the SYSTEM menu. There you can change
the threshold point for each of these settings to customize
the KOMPRESSOR effect to fit your speakers, car or personal
tastes.
A few words on the Kompressor. The effect is most
noticeable in the bass area of your music and the
descriptions above apply to that area of your music
(Bass/Midbass). You can use the Kompressor in any amplifier
configuration (Low Pass, High Pass, Band Pass or Full Range)
but we feel the best results are obtained when with the amp
is in a Low Pass (subwoofer) or Band Pass (midbass) situation.
A few exceptions to this rule are:
The
red-line setting is good for use in any configuration
as it helps control dynamic peaks and limit distortion at
higher output levels.
The
contour setting is also another good all around use
setting and when used in Full Range or High Pass
configurations tends to enhance the vocal and top end of
the music. Great for helping to cover up interior noise.
The
ATTACK setting is really geared for bass and midbass
duty.
The possibilities are almost endless! Tweak away!
