3. Stereo Bus Compressor
INTRODUCTION
The Stereo Bus Compressor plug-in is a stereo version of the legendary centre section stereo bus compressor found on the
XL 9000 K Series console. It provides high quality stereo compression, giving you critical control over the dynamic range of
audio signals.
The compressor can be run in mono or stereo modes and can be used for practically any application that requires superior
compression. For example, place it over a stereo mix to ‘glue’ the mix together whilst still maintaining a big sound, or use it
on drum overheads or whole drum kits for very effective control of drum dynamics.
INTERFACE TECHNIQUES
• To press a switch in a plugin, simply click on it.
• To turn a knob, click on it, and drag it up and to the right (as shown right). If your mouse has a scroll
wheel, you can also turn knobs by hovering over them and turning the scroll wheel.
• To turn a knob slowly for fine adjustments, hold Shift on your keyboard whilst turning. To reset a knob to
its default value, click on it whilst holding Ctrl (Windows) or ⌘ (Macintosh).
• To view the value for any knob, hover over the knob cap with the mouse. The current value will appear
immediately above the knob (shown left).
Every plug-in parameter can be automated in host applications which supports automation. The method
for recording and editing automation varies from host to host. For specific instructions on using automation
with the host consult the host application documentation.
CONTROL PARAMETERS
Below is a description of the Stereo Bus Compressor’s parameters, as shown in the diagrams
to the right. If you are unfamiliar with how to use any of the parameters described, please
