User manual


Links requires a -12V/+12V power supply (2x5 pin connector). The ribbon cable connector must be aligned so that the red stripe of the ribbon cable (-12V) is on the same side of the module’s power header as the “Red stripe” marking on the board. The module draws 15mA from both the +12V and -12V supply rails.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This device meets the requirements of the following standards: EN55032, EN55103-2, EN61000-3-2, EN61000-3-3, EN62311.

1:3 section

This section of the module is a buffered multiple. The signal patched to the IN input is duplicated, without voltage drop, to each of the three OUT outputs.

This section can be used to send the note CV from a keyboard, sequencer or MIDI interface to several VCOs; but it can also distribute an audio signal or modulation to several modules.

2:2 section

This section acts as a precision adder/mixer and as a multiple. The two signals patched in the IN inputs are added, and the result is made available on each of the two OUT outputs.

It is of course possible to use this section as a 1:2 multiple - when only one of the IN inputs is left unpatched.

Because this section uses a precision adder circuit, it is possible to use it to transpose a note CV: for example, patch the CV output of a sequencer to the first input, and the CV output of a keyboard to the second input. Patch the output(s) to (a) VCO(s). With this patch, the sequence is transposed by the keyboard.

Audio or modulation signals can also be mixed and/or multed by this section.

3:1 section

This section acts as an averager. The three signals sent to each of the IN inputs are mixed together, with a gain of 13 applied to the mix. It is particularly useful for mixing audio signals without causing clipping.
