Unpacking
Your BISON 00 has been carefully and meticulously tested and inspected before dispatch.
Please check for any signs of transit damage. If any signs of mishandling are found please
notify the carrier and your dealer immediately.
Your BISON 00 packing should contain the BISON 00 with IGS Audio tag (packed in ESD

Compatibility and Power
The BISON 00 module is designed to be installed into an API™ 00 Series compatible rack
and cannot function stand alone, requiring the power source supplied by the rack system.
The current consumption of the BISON 00 is rated at 180 milliamperes. Please check with the
rack manufacturer that the design can meet this rating.
Mounting
WARNING! Never plug or unplug any 00 series module with the power supply switched on.
You may destroy your unit permanently!
The dimensions of all IGS Audio 00 series modules are compatible with API standard. When
plugging your new unit to the 00-series rack, no unnecessary force is needed. However,
please be careful and do not rush while pushing the unit into the rack sockets, to avoid
damaging of the connectors and/or the PCBs of either the unit or the rack.
After the unit is placed in the rack, use the screws provided with your 00-series rack unit to
make sure that the unit is safely placed.
When removing the unit from the rack, unscrew the front panel from the rack, and use your
fingers to pull it out gently. Do not use any sharp objects (i.e. knives or screwdrivers) to prize it.

IGS AUDIO BISON 500 – stereo parallel mixer with Mid/Side processing
The IGS Bison 00 is a simple mid/side processor with a dry/wet mixer. It has two stereo jack
connectors (2 sends and 2 returns) on the front panel of the device used for plugging in your
favorite dual mono or two mono compressors.
With a flick of the switch your compressor(s) start working in Mid/Side mode, where the left
channel controls the common/Mid section of the two channels and the right channel controls the
difference between the channels referred to as Side. Adding more sides or compressing them
differently can increase your stereo image significantly. Always use balanced inserts.
The dry/wet knob can be very useful for parallel mixing. It is great for situations, where you want
to pump up the sound without losing the natural dynamics of the dry mix.
4 balanced inserts: 2 sends, 2 returns
3-position switch: stereo, bypass, Mid/Side
Mix knob range: (Dry) 0% - 100% (Wet)
Typical usage:
–Widening your stereo image
–Parallel compression
–Using different compressors for mid and sides
