VCA (Voltage Controlled Amplifier)
After being shaped by the filter, the audio signal passes on to the voltage
controlled amplifier (VCA). The Super 6 contains an analog amplifier
section that can further be used to shape the sound by adjusting and
modulating the amplitude or loudness over time.
By default, the amplitude is controlled by envelope 2 (ENV 2) which gives
you control over the attack, decay, sustain, and release stages. You
will learn more about how the VCA can be modulated by the dedicated
envelope in the section that covers the functionality of envelope 2 (see
). Alternatively, the VCA can be controlled by one of two fixed
envelopes, allowing the second envelope to be freed up for other duties if
so desired.
The VCA section.
ENV LEVEL:
This fader allows you to adjust the amount at which envelope
2 or one of the two fixed envelopes will modulate the VCA’s amplitude over
time. The envelope level control is used in conjunction with the envelope
selector toggle switch.
Depending on the level of the signals that are being fed into the
VCA section, high ENV LEVEL settings may cause the amplified
output signal to clip or to distort regardless of the MASTER
VOLUME setting. Simply reduce the ENV LEVEL settings to avoid
undesired clipping artifacts and to ensure a clean signal at the end
of the signal chain.
