Module Installation
With your modular synth powered off, connect the 10 pin end of the supplied
standard eurorack power connector cable to the 10 pin power connector on the
rear of the module.
The red stripe on the cable should be orientated to match the text ‘RED’
marked on the rear of the module near the power connector (this is -12V).
Connect the other 16 pin end of the cable to your eurorack bus board (Refer to
your bus board documentation for the correct orientation).
You are now safe to power up your modular synth. If the module fails to power
up, check that you have the power cable correctly orientated and have
carefully read the manual.
The ‘Stereo Sum’ is a unity gain summing mixer that features four stereo input
pairs summed as pairs to two independent mix outs or all as a single combined
mix. It is a useful utility for efficiently combining outputs of multiple
stereo sources, such as the MEGA-TANG and Jumble Henge mixers or multiple MFX
returns. The inputs accept stereo or mono signals (via normalisation) which
can be audio or CV (module is DC coupled) and the top mixer’s outputs are
normalised to the bottom mixer section meaning if the upper output is left
unpatched the two upper inputs will be added to the lower output.
