X-Series MKII Dual Oscillator

Dual Oscillator Module

Fully analog double oscillator with integrated ring modulator based on the MC1496 chip which appears in many vintage synth designs from the 1970's. Cross modulation, linear FM, are all on board. A lot of VCO and a lot of knob on 42HP. Together with the Macbeth backend filter, the combination provides a full and high-quality complex voice.

New features to the predecessor:
-transistor pairs are more closely matched in this version. This provides increased tuning stability and allows better tracking.
-Precise multi-turn potentiometers provide additional signal stability and simplify the calibration of the oscillators
-use of very high quality parts in the entire signal path. Significant improvement in the choice of capacitors.
-The output section of the oscillators has changed significantly and now each oscillator is joined by two sub-oscillator outputs. The change is as follows:
MKI: SAW / RAMP / SQU / RECT / TRI / SINE
MKII: SAW / RECT / TRI / SINE and now also SUB-OCTAVE ONE / SUB-OCTAVE TWO (you can expect a massive sound here)
-The 10-turn potentiometers have been retained and make fine-tune controls obsolete
-The noise generator now contains a double potentiometer and a summing amplifier/mixer circuit for the white and pink output.
-The ring modulator remains the same and is based on the balanced modulator IC MC1496.
-In addition to the 16-pin Doepfer standard bus connector for the power supply, the rarely used CV bus is now also used
-The jack sockets have been revised. On the original X-Series, Ken Macbeth had used the same type of 'box jack' that many others use. Ken began to question the reliability of this type of plug - and now with the MK2 versions about to be launched, he felt it was important to upgrade the jacks to a higher quality type. As far as plugging is concerned, they will have a much longer life, which in turn will increase reliability".
