It is powered by a center negative DC 9V adapter or a single 9V battery.

It contains two VCOs (oscillators) with a wide range.

The SUB oscillator has a different frequency and waveform, and is input to the main, respectively. Each of them has a range switch, so it works like an LFO under the switch. The color of the range switch (white, black) corresponds to the color of the SUB.1 and SUB.2 on-off switches next to the FREQ knob of the main oscillator.

When the WAVE switch is turned on, the WAVE knob is activated, and the SUB OSCILLATOR.1 and 2 are shaken.

The main VCO×2 is mixed and fed into the strain + filter circuit. This special filter has a FREQ knob and a TUNE knob. The TUNE knob powerfully amplifies the input signal while also tracking specific pronunciations.

The filter is a circuit that has been fine-tuned so that it can very effectively enhance the bass and treble of this input signal.

Unlike other switches, the noise-on switch moves sideways, left (VCO.1), middle (OFF), and right (VCO.2). They are populated in VCO.1 and 2, respectively.

It is a noise machine that can output a very strong signal that generates a variety of noise sounds.

This analogue synth runs on DC9V negative center or a 9V battery.

The main 2 VCOs can receive 2 oscillators and noise generator inside and go to 2 different filters.

2 oscillators can be tuned with each two FREQ. knobs and controlled with the wave knob.

RED switch is for wave knob working.

Black and White for tone of oscillators
