(9)VCF/VCA SIG IN – Connect incoming signals via 3.5 mm TS cables.
(10)SIG LEVEL – Adjust the level of the signals connected to the inputs.
(11)VCA OUT – Sends the VCA signal via 3.5 mm TS cable with either high or low signal levels.
(12)INITIAL GAIN – Adjusts the initial gain level when there is no control voltage present. The adjacent LEDs will light to indicate signal (green) and overload (red).
(13)MOD LEVEL – Adjusts the level of the signal connected to the associated MOD IN jack.
(14)MOD IN – Accepts voltages that control or modulate the VCO, VCF or VCA.
(10)Power Connection

|
The module comes with the required power cable for connecting |
||
(13) |
to a standard Eurorack power supply system. Follow these |
||
|
steps to connect power to the module. It is easier to make |
||
|
these connections before the module has been mounted into |
||
(14) |
a rack case. |
||
1. |
Turn the power supply or rack case power off and |
||
|
disconnect the power cable.
(1)PW MOD – Accepts a voltage from another module to control the pulse width. When a jack is inserted the
MOD MANUAL control acts as a MOD input level control.
(2)VCO OUT – Send the VCO signal to another source via 3.5 mm TS cable.
(3)WAVEFORM – Select triangle, sawtooth or pulse waveforms for the VCO.
(4)MOD MANUAL – Sets the ratio between the upper and lower portions of the pulse wave.
(5)RES – Boosts the resonance frequencies selected with the CUTOFF FREQ slider, potentially causing VCF oscillation.
(6)CUTOFF FREQ – Adjusts the cutoff frequency of the low-pass filter.
2.Insert the 16-pin connector on the power cable into the socket on the power supply or rack case. The connector has a tab that will align with the gap in the socket, so it cannot be inserted incorrectly. If the power supply does not have a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
3.Insert the 10-pin connector into the socket on the back of the module. The connector has a tab that will align with the socket for correct orientation.
4.After both ends of the power cable have been securely attached, you may mount the module in a case and turn on the power supply.
(7)RANGE – Sets the pitch range of the VCO in octave steps.
(8)PITCH – Fine tunes the pitch.
