Patching in a Compressor

Patching in a Compressor

ProMix 01 features three stereo dynamics processors, for compres-
sion, limiting, gating and ducking. Here we'll patch a compressor into
the stereo output to add some punch.
1. Press [COMP].
The COMP LCD function shown below appears.
2. Use the cursor buttons to select PATCH.
3. Use the PARAMETER wheel to select STEREO.
STEREO flashes.
4. Press [ENTER] to confirm.
Dynamics processor #1 is patched into the stereo outputs and the
sound is compressed. Program #1 (TOTAL COMP) provides 2:1
compression above a 0dB threshold. This means that for every 1dB
change in input signal level above 0dB there will be a 0.5dB change
in output level. This means that you can increase the output level a
little without the risk of clipping. Essentially, signals above the thresh-
old level are compressed, while those below are effectively increased
in level due to the fact that you've increased the output level using the
ST OUT fader. In other words, the dynamic range (i.e. the range of
levels from quiet to loud) has been compressed.
The compressor's output signal level and the amount of gain reduc-
tion (GR) applied is indicated on the display. The GR meter works
from top-to-bottom.
5. To perform A–B listening tests, select ON/OFF and use the
PARAMETER wheel to switch the compressor ON and OFF.
With COMP1 turned ON you can raise the ST OUT fader higher than
0dB and the overall output volume changes very little.
If you're happy with the compressed sound, go to the next section. If
not, select PATCH and set it to OFF. Remember to press [ENTER] to
confirm.
