4.2.5. Limiter Section (Main Panel)
This is where you control the Limiter section of the Comp DIODE-609. A Limiter is a special
kind of compressor, that basically acts as a ceiling for the audio, with an infinite ratio
compression. That's why you don't have a ratio controller here.
4.2.5.1. Threshold
The Threshold here works in much the same way as in the Compressor section. This is
where you define the level around which the Limiter section starts to act (in this case, it is
the ceiling the audio level will reach). The behavior of the Threshold depends on the knee,
as is the case with the Compressor, but the Limiter curve is much harder.
In the Limiter section, the Threshold has the same range as in the Compressor section.
Therefore, it goes as low as -40 dB (meaning almost any audio will be limited) and all the
way up to 0 dB (basically no limiting). A good range usually varies from -3 dB to 0 dB. On a
masterbus, limiting is just a safety measure, therefore the threshold shouldn't be very low.
Ideally, the Threshold here should be set so that it is rarely reached. By default, it is
positioned at 0 dB, which we can consider a "neutral" position (basically, no limiting).
The limiter ratio of the Comp DIODE-609 is very high. Therefore, any value above the
Threshold is effectively prevented from leaving the plug-in.
4.2.5.2. Recovery
The Recovery in the Limiter section is very similar to its counterpart in the Compressor
section. The only difference is the values available. In this case, you can go lower (which is
understandable, since this is a Limiter, and the audio needs to recover faster from limiting).
The fastest Recovery value is 50 ms, and you have 100 ms, 200 ms and 800 ms. Besides
these fixed values (which are much lower than those available in the Compressor, as you
have probably noticed), we also have the automatic "
a1
" and "
a2
" positions.
As explained in the hands-on section and the Compressor section, these are automatic,
program-dependent recovery times. This means that the recovery (release) time is
controlled by the signal so that it is shorter for isolated peaks and extended in the case of
high average levels. The
a1
position has a release that varies from 100 ms to 2 seconds. The
a2
position has a release that varies from 50 ms to 5 seconds.
By default, the Limiter Recovery time is set to 50 ms.
