Knead is a transistor based 3-channel analog mixer module with integrated EQ and
Mute switch. The mixer is especially designed to knead single audio waveforms, but
will of course also handle more complex audio sources.
The circuit adds some nice harmonic distortion to the signal with heavy clipping,
if the inputs are turned to the maximum.
As the mix is bussed passively turning one input up may result in a reduction of
the other inputs. Therefore the output cannot exceed any other input´s level providing
auto-leveling on high volumes.
There are three potentiometers to adjust the LEVEL for each signal. Additionally
you may change the frequencies of each channel by turning the EQ knobs. On top you
will find MUTE switches for easy sound comparison or live mixing. LEDs will indicate
if a signal is passed through. The LED´s brightness can be set with trim potentiometers
for each channel. The MIX VOL knob controls the volume of the summed signal being
supplied at the OUT Jack.
Knead Expander is an optional 2HP add-on module providing a wider range of functionality
without using an additional power socket.
In order to use LEVEL, EQ and MUTE individually just connect the Knead Expander to
the main module with a ribbon cable. This gives you additional three illuminated
single outs in order to patch a single channel to your audio patch without being
summed with the other signals.
As channel three is connected to the other two channels via a JFET Amplifier, it
can be used for amplitude modulation. This way you will get a very simple Waveshaper,
VCA or Ringmodulator.
