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!
