IGS Audio / BISON 500

An M/S processor module that converts dual mono compressors and EQs into parallel-capable M/S devices.

The Bison 500 from IGS Audio is a simple M/S processor with a dry/wet mixer that can be connected to a 500 series rack. The front panel of the device is equipped with two stereo jack connectors (send and return) to connect your favorite dual mono or two mono compressors or EQs. It's one of those devices that can produce amazing results with simple operation.

When switched on, the connected compressor or EQ starts working in mid/side mode. In this mode, the left channel controls the mid section and the right channel controls the side channel. This device can be used to generate a more beautiful stereo image.
