Audio / CV Processors
Overview
The audio / cv processors are two independent processors that can be summed together to
expand their functionality. Together they can be used as a 2 channel mixer or single channel
amplifier with positive or negative offset.
Amplifier
Amplifier is for audio signals only. The range is full attenuation to 10x amplification. The amplifier
can be used to amplify external signal to eurorack modular levels or to overdrive eurorack level
signals. Set output using the [AMPLIFIER KNOB]. [AMP INPUT JACK] and [AMP OUTPUT JACK] are
used to patch in and out of the amplifier. If the [AMP OUTPUT JACK] is not patched, the output of
the amplifier is mixed with the output of the attenuverter. This can be used for driving internal
signals
Attenuverter / Static DC Voltage Source
The attenuverter is for both audio and CV signals. Set the output using the [ATTENUVERTER KNOB].
[ATTEN INPUT JACK] and [ATTEN OUTPUT JACK] are used to patch in and out of the attenuator. If
the [ATTEN INPUT JACK] is not patched, the attenuator will output -5v to +5v DC.
Audio / CV Processors Input Jacks :
[AMP INPUT JACK] Amplifier input jack.
[ATTEN INPUT JACK] Attenuverter input jack.
Audio / CV Processors Output Jacks :
[AMP OUTPUT JACK] Amplifier output jack.
[ATTEN OUTPUT JACK] Attenuverter output jack.
LFO
The LFO module is an analog, dual range, low frequency oscillator with +/- 5 volt triangle and
square wave outputs. Select between high and low range by holding down the voice module’s
[EDIT BUTTON] and pressing the [HARD SYNC BUTTON].
LFO Ranges:
High: 2 Hz to 500 Hz
Low: 41 seconds to 5 Hz
LFO Output Jacks :
[TRIANGLE JACK] Triangle wave LFO output jack.
[SQUARE JACK] Square wave LFO output jack.
