Synthrotek - Combine-OR

We currently have 3 of these in stock.


Need more OR?  The Combine-OR is an 8 channel OR-Combiner with 4 inputs and 1 output per channel.

The Combine-OR allows the user to combine gates, triggers and other logic signals into a single combined OR output.

There are 8 numbered rows that can be daisy-chained in order to input many multiple logic sources, resulting in complex gate or trigger outputs.

This is a passive module and thus does not need a voltage connection or power cable.  The passive diodes produce a slight voltage drop between the input and the output of each channel. As a gate combiner it will combine 2 to 4 gate inputs to produce an OR function on the output. When combining CVs the highest positive input will appear at the output with about 0.7 volts of drop.
