5.2.3  Compression Setting Suggestions
The following are the compression presets that were used in 
the PreSonus BlueMax. We have included them as a jumping-
off point for setting up compression in Studio One Artist.
Vocals
Soft. This is an easy compression with a low ratio setting for ballads, allowing a wider 
dynamic range. It’s good for live use. This setting helps the vocal “sit in the track.”

Medium. This setting has more limiting than the Soft compression setting, 
producing a narrower dynamic range. It moves the vocal more up front in the mix.

Screamer. This setting is for loud vocals. It is a fairly hard compression setting for 
a vocalist who is on and off the microphone a lot. It puts the voice “in your face.”

Percussion
Snare/Kick. This setting allows the first transient through and compresses 
the rest of the signal, giving a hard “snap” up front and a longer release.

Left/Right (Stereo) Overheads. The low ratio and threshold in this 
setting gives a “fat” contour to even out the sound from overhead 
drum mics. Low end is increased, and the overall sound is more 
present and less ambient. You get more “boom” and less “room.”

Fretted Instruments
Electric Bass. The fast attack and slow release in this setting will tighten 
up the electric bass and give you control for a more consistent level.

Acoustic Guitar. This setting accentuates the attack of the 
acoustic guitar and helps maintain an even signal level, keeping 
the acoustic guitar from disappearing in the track.

Electric Guitar. This is a setting for “crunch” electric rhythm 
guitar. A slow attack helps to get the electric rhythm guitar “up 
close and personal” and gives punch to your crunch.
