Mackie DL806 and DL1608 Reference Guide Chapter 13: Channel View : Output Compressor / Limiter Introduction The output compressor / limiter looks and functions similar to that of the channel compressor, except (1) the output compressor / limiter affects and alters the sound of everything passing through the selected output and (2) the output compressor / limiter output is in stereo. Compressors are used to reduce or limit transient peaks in a signal. If the signal is too hot, turn it down, otherwise leave it alone. As the input level to the compressor increases, the output level increases linearly until the threshold point is reached. After that point, the output level no longer increases linearly. Instead, it increases at a reduced rate determined by the ratio setting. With limiters, signals below a specified input level are allowed to pass unaffected while attenuating the peaks of stronger signals that exceed the input levels. The attack and release controls affect the rate of the gain change; attack affects the rate of the onset of gain reduction and release affects the recovery rate once the transient has passed. There are actually two different types of output compressor / limiters to choose from on each channel: the clean, surgical modern output compressor / limiter and classic sounding vintage output compressor / limiter. That's right, you can mix and match to heart's content! We will dissect both the modern and vintage output compressor / limiter separately, but let's begin by taking a peek at what features apply to both. The modern output compressor / limiter is discussed further on pages 80-81, while more information about the vintage output compressor / limiter may be found on page 82.

Chapter 13: Channel View : Output Compressor / Limiter
Introduction
The output compressor / limiter looks and functions similar to that of the channel compressor, except
(1) the output compressor / limiter affects and alters the sound of
everything
passing through the selected
output and (2) the output compressor / limiter output is in stereo.
Compressors are used to reduce or limit transient peaks in a signal. If the signal is too hot, turn it
down, otherwise leave it alone. As the input level to the compressor increases, the output level
increases linearly until the threshold point is reached. After that point, the output level no longer
increases linearly. Instead, it increases at a reduced rate determined by the ratio setting.
With limiters, signals below a specified input level are allowed to pass unaffected while attenuating
the peaks of stronger signals that exceed the input levels.
The attack and release controls affect the rate of the gain change; attack affects the rate of the
onset of gain reduction and release affects the recovery rate once the transient has passed.
There are actually two different types of output compressor / limiters to choose from on each channel:
the clean, surgical modern output compressor / limiter and classic sounding vintage output compressor /
limiter. That’s right, you can mix and match to heart’s content! We will dissect both the modern and vintage
output compressor / limiter separately, but let’s begin by taking a peek at what features apply to both.
The modern output compressor / limiter is discussed further on pages 80-81, while more information
about the vintage output compressor / limiter may be found on page 82.
Output Compressor / Limiter On / Off
Press the Comp button to turn the compressor on or off. It will illuminate green when engaged and is gray
when disengaged.
Modern / Vintage
The modern / vintage button is located directly to the right of the comp on / off button. It displays
the compressor type currently in use, with “Modern” as the default. Tap this button to reveal the
two compressor types, then tap the compressor you would like. The image will change to reflect
the compressor type chosen.
Modern Output Compressor / Limiter Introduction
As mentioned previously, the modern output compressor / limiter is designed for clean, surgical processing;
it’s great for dialing in a nice, tight sound. As such, the attack, release and ratio features may be fine-tuned
when the modern output compressor / limiter is utilized. Now for a detailed (let’s say“surgical”) look at the
modern output compressor / limiter.
