Quick Start Guide
OSCILLATOR MODULE 1004
Legendary 2500 Series Dual Core VCO
Module for Eurorack
Controls
(1)
COARSE FREQUENCY
– Sets the frequency from 0.03 to
32 Hz in the low (LFO) range, or from 15.5 Hz to 16 kHz in
the high (audio) range, depending on the Fine frequency
knob setting.
(2)
FINE FREQUENCY
– Adjusts the frequency by a factor of
±1 octave, potentially halving or doubling the frequency
at either extreme.
(3)
ENABLE switch
– Turns the oscillator on and off.
(4)
RANGE switch
– Determines whether the oscillator
operates in the low (subsonic/LFO) band or the high
(audio) band.
(5)
WAVEFORM switches
– Engage up to 5 waveforms by
moving the relevant toggle switch to the left, or engage
the inverse waveform by moving the switch to the right.
The center position turns the waveform off. Engaging
multiple switches simultaneously produces the average of
all active waveforms.
(6)
PW knob
– Manually control the pulse width for the
pulse waveform.
(7)
FM 2 knob
– Attenuates the signal connected to the FM
2 input.
(8)
PWM knob
– Adjusts the modulation depth of the PMW
control input.
(9)
FM 1 knob
– Attenuates the signal connected to the FM
1 input.
(10)
KYBD
– Connect a keyboard or other external frequency
control via 3.5 mm TS cable.
(11)
FM 1/2
– Connect external voltages to modulate
the frequency.
(12)
PWM
– Connect an external voltage to modulate the
pulse width.
(13)
OUT
– Send the oscillator signal to other modules via
3.5 mm TS cable.
Power Connection
The unit comes with the required power cable for connecting
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
a rack case.
1.
Turn the power supply or rack case power off and
disconnect the power cable.
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.
