Audio Signal Path Diagram

The 2-pole Filter is a full analog signal processor with the following signal path:
The input signal is first pre-amplified and then sent to the proces­sing circuitry. This processing consists in a chain of three ele­ments: Rectifier module - Multimode filter - Overdrive module.
Finally, the signal is attenuated and buffered to provide the output.
w The Activate switch provides a true bypass functionality
on the signal path. When deactivated, the input jack is physically connected to the output jack and the 2-pole has no influence on the audio signal.
