Bare PCB

The main PCB and the oscillator PCB for building the M²Synth Chord VCO 102 in either MOTM or MU format.  All pots and switches are soldered direct to the back of the main PCB (coloured blue on the PCB layout) so no panel wiring. Supplied complete with circuit schematic. Main PCB size 87.5 x 155mm, oscillator PCB 87.5 x 131mm.

Power Supply Voltage

M2Synth modules are designed for +/-12V operation and we use a 10-pin IDC box header as our standard power supply connector. MOTM and MU systems use a different header and operate at +/-15V. To cater for the higher voltage and different power supply connectors we have an in-line voltage regulator conversion module if you intend to install the finished module in your own MOTM/MU system.

For the Chord VCO 102 you will require two of the regulator modules.

The regulator module can handle up to +/- 100mA maximum although we suggest +/-90mA is a practical safe limit. The module has the added advantage of providing a stable +/-12V to the module and reduces the risk of supply voltage fluctuations from other modules or power supply drift from affecting the supplied module. This ready assembled and tested module can be ordered along with the PCB. For the Voice 108 you will require two of the regulator modules.

Complete Kit

We can supply the Chord VCO 102 a complete kit of parts for MOTM or MU formats offering a saving over purchasing items individually.

Ready Built

Prefer not to solder, a ready assembled version in MU or MOTM versions can be purchased direct from our dedicated website at m2synth.com

Advice

This kit is not suitable for those new to electronics assembly and requires test equipment to calibrate the module. For more info about assembling M²Synth modules see this guide
