REFERENCE MANUAL
Inputs & Outputs
The ZEROGRAVITY FILTER has 2 audio inputs and outputs and accepts line level signals. Input
1 will be routed to both channels if input 2 is left open.
If the input level e4dBu (0VU), the saturation LED will turn red. At this point distortion
will occur, even with the saturation control fully down.
The EXT source input is routed to the envelope generator.
The MIDI INPUT can be used to synchronise the LFO with MIDI clock, and to control the filter
externally.
All MIDI in data is sent out on the MIDI THRU.
A 15V AC adapter (at least 0.5A) must be connected to the POWER input.

The LED will change from green (clean) to orange (distortion).
The corresponding ENV control uses the output of the envelope generator to modulate the amount
of saturation.
When the knob is in the middle, no change will occur. When turned to the right, the envelope signal
