Product Overview & Features

Bus Compressor 2

The Bus Compressor 2 plug-in is based on the legendary centre section bus compressor found on SSL's large format
analogue consoles. It provides high quality stereo compression for critical control over the dynamic range of audio
signals. The compressor 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
highly effective control of drum dynamics.

Bus Compressor Controls

THRESHOLD controls the level at which gain reduction is introduced.
MAKEUP provides a gain stage to compensate for any reduction in level caused by the compression.
ATTACK controls the response time of the onset of compression once the threshold is crossed. New in Bus Compressor 2 is the
20 ms option.
RELEASE controls how quickly the level returns to normal. New in Bus Compressor 2 are the .4, .8 and 1.2 second options.
RATIO controls the degree of compression. New in Bus Compressor 2 are the 1.5, 3, 10, 20 and X options. X is the most aggressive
option and is greater than 20 but less than infinity to one.
S/C HPF applies a high-pass filter to the compressor sidechain.
MIX controls the blend of 'dry' uncompressed signal and 'wet' compressed signal.
IN when switched out, the Bus Compressor is bypassed. This is linked to the DAW's insert bypass feature.

Gain Reduction Meter

The meter shows how much gain reduction is being applied by the Bus
Compressor 2 plug-in in the style of the classic moving-coil meter found on
SSL consoles.

Oversampling

Bus Compressor 2 features the ability to use oversampling DSP. Options
are provided for none (OFF), 2x and 4x. When compressing material
heavily (e.g. smashing a drum bus), you may want to experiment utilising
Gain Reduction oversampling, as it will help to reduce unfavourable distortion that may
Meter
be being introduced. The DAW will introduce a small amount of delay
compensation for Bus Compressor 2 when oversampling is used.

Settings
The button labelled PLUG-IN MIXER opens the SSL 360° on the Plug-in Mixer
page (presuming SSL 360° is installed). Otherwise, it will take you to the SSL
Opens 360° website.

External S/C and Mix Lock

The EXTERNAL S/C button allows the Bus Compressor sidechain to be fed
Bus Compressor
from a source different to the internal sidechain. e.g. A bus send could be set
Mix Lock
up in the DAW, such as a kick drum that could be used to creatively 'pump'
the Bus Compressor. Please note you will need to determine the external
sidechain source using your DAW's plug-in header bar.
MIX LOCK excludes the MIX control from the preset system, which can be useful for auditioning different presets, without the MIX
control responding to the preset being loaded.

Undo/Redo and A/B

Undo/Redo actions can be made to plug-in parameters using the UNDO and REDO buttons. A/B buttons allow you to load two
independent settings and compare them quickly.
Clicking in the Default Preset area will allow for access to the Preset Management List. The Preset Management list allows you to
load factory or user-saved presets, as well as some other options shown overleaf.
