The centre section compressor from the 1980's G-Series analogue console is an audio production legend. It is a simple unit with a simple purpose; it makes complete mixes sound bigger, with more power, punch and drive. It brings cohesion and strength to your mix without compromising clarity. The Stereo Bus Compressor Module brings this classic "…audio glue' to you with spectacular SuperAnalogue audio performance. Features:
- Classic sonic character and mix finalising capabilities of SSL Stereo Bus Compression
- True Stereo side-chain input for external signal keying
- Link control enables several modules to be combined for surround compression
- Gain reduction meter as fitted to the classic SSL console range
- Electronically balanced XLR connections
The rear panel of this dual width module carries two Input XLRs ("…IN L' and "…IN R'), two Key Input XLRs ("…KEY L' and "…KEY R') and two Output XLRs ("…OUT L' and "…OUT R'). Connect the two inputs to the main output insert sends of your console or to your workstation outputs. Connect the outputs to the corresponding insert returns or to your workstation inputs.
Once the module is connected switch the XRack on, then route signal to each channel in turn and check that the signal is returned to the correct input on your console or workstation. The module input and output gains can be set to operate at a nominal level of either +4dBu or "–10dBV, using the switch on the connector panel "– select the appropriate level for the equipment you are connecting to.
Operation:The X-Rack Stereo Compressor module is designed to provide flexible control over a stereo mix. The compressor design is based around the Bus Compressor found in the XL 9000 K Series console.compressor Controls: The main VCA is permanently in circuit; the compressor sidechain is enabled by the IN switch. The other sidechain controls are equally straight forward and hopefully require little explanation.The ATTACK, RATIO and RELEASE controls are multi-position switches; switches; the THRESHOLD and MAKE-UP controls are continuously variable potentiometers.
Key Input:The compressor sidechain can be driven either by the main stereo channel signal(s) where the loudest signal wins and provides the sidechain signal, or by an external signal applied to the "…KEY' input(s) on the rear of the module continuously variable potentiometers.This feature is enabled by the KEY switch on the front panel and opens up the possibility to use the unit as a "…ducker' (for audiofollow applications) or, with external EQ, as a "…de-esser'.
Link Bus:A further option, selected by the LINK switch, is a sidechain link bus which enables multiple modules to be used together to create a multi-channel compressor. The combined sidechain can be driven from any of the Key Inputs and will of course operate on a "…loudest wins' basis.
