The PeakPlus limiter uses Intelligent Predictive Limiting to determine how much gain reduction to apply and can be used for
level-critical applications, where you want to keep dynamics under control no matter how loud the source becomes.

1. Comp/Lim Enable Button
Press this button to enable/disable the compressor and limiter – the compressor and limiter are enabled when the
button’s LED is lit.
2. Compression Threshold LED Meter
These three LEDs indicate the relationship between the input signal level and the compressor’s threshold setting.
•
When lit, the red ‘+’ LED indicates that the signal level is above the currently set threshold and
compression will be applied according to the RATIO control setting.
•
When lit, the yellow ‘O’ LED indicates that the signal level is approaching the currently set threshold
and is in the OverEasy™ region. Some minor compression will begin to be applied in this OverEasy
region and full compression will be applied if the signal level does exceed threshold. Note that this
LED only functions when the OVEREASY button is engaged.
•
When lit, the green ‘-’ LED indicates that the signal level is below the currently set threshold and no
compression is being applied.
3. Threshold Control [-40 dB to +20 dB]
This control sets the level at which the compressor will begin compressing.
4. OverEasy Button
This button toggles the OverEasy feature on and off. When OverEasy is enabled, the compressor will act as a ‘soft-knee’
compressor, meaning that compression is applied more gradually as it approaches the threshold and is then fully
compressed once the threshold is exceeded. This mode provides softer, more musical, and less obvious compression
when tracking vocals, clean electric guitar, and bass. When OverEasy is disabled, the compressor will act as a ‘hard-knee’
compressor, which is better suited when you want a more up-front and aggressive sound and can work well for drums
and other percussive instruments.
5. Ratio Control [1:1 to
∞
:1]
This control sets the amount of gain reduction applied when compression occurs. For example, when the ratio is set
to 4:1, the output level will increase by only 1 dB for every 4 dB of signal level over the set threshold. So, using this
example, if the signal level were to exceed the threshold by 8 dB, the increase in level post-compression would be only
2 dB – meaning 6 dB of gain reduction has been applied. Conversely, a ratio setting of 1:1 would yield no difference in
