BUS is a two channel, 2->3 buffered multiple in 6HP, with 5V offset and bi-color indication of signal amplitude and polarity. BUS provides a way to send voltages to multiple places in your rack with high precision, and put those signals on the CV and GATE Bus on a standard Eurorack power supply. The left channel, labelled "CV", has a variable DC offset control via the pot labelled "OFFSET". The two inputs are summed with unity gain, and the overall gain of each channel can be dialed in via the trim pots on the back of the module. The latching push buttons labelled "BUS" connect the associated inputs to the respective power supply bus.
