• Limited-edition run
Troubleshooting:
Problem:
Kicker does not power up
Solution:
Check the polarity of the DC adapter. The ‘TIP” must be Negative (-)
Problem:
The Audio Trigger doesn’t appear to be doing anything
Solution:
The threshold for the Audio Trigger is approx. -6dB. Try slowly turning up
the volume of the signal you are using as your Audio Trigger
Problem:
The Audio Output sounds like it is overly distorted using the Audio Trigger
Solution:
If the volume of the signal your are using as your Audio Trigger is set too
high it will distort the triggered sound. Try slowly turning down the volume
of the signal your are using as your Audio Trigger
Problem:
The Audio Output sounds like it is overly distorted using the CV Trigger
Solution:
The CV Trigger must be short enough to trigger the internal oscillators
without distorting them. Most MIDI to CV converters, analog trigger outs
and DC (or positive going) oscillators with a good pulse-width control
should be able to trigger Kicker without problems
Problem:
The Envelope Decay control seems to have stopped working
Solution:
Kicker uses a ‘non-retriggering’ Attack/Decay Envelope. It is possible,
when using a Decay time that is much slower (longer) than the trigger
speed (Tempo), that the Decay section of the Envelope Generator might
briefly ‘latch up’. This is intentional and using the tail of the Decay portion
of the Envelope to affect the Attack section can produce great results.
To reset the ‘latch-up’ simply turn the Decay time back down
Problem:
Oscillator 2 has gone mad
Solution:
The OSC2 PARAM1 and OSC2 PARAM2 controls are linked. They must
both be set in order to achieve the desired sound. They both have an affect
on the Pitch and Decay of Oscillator 2 before it is routed to the VCA.
It is possible to push Oscillator 2 into ‘self-oscillation’ so that it will continue
to sound even though there is no trigger input. If this is a problem slowly and
gradually lower both OSC2 PARAM1 and OSC2 PARAM2 until the oscillations
only occur on triggering
