Buff Mult 1U Manual
Operation
Buff Mult 1U is a dual 1 x 4 buffered signal multiplier. A signal multiplier takes an input signal
and routes it to multiple outputs simultaneously. For example, you might want to route
keyboard’s pitch CV to three different destinations: one to govern the pitch of your main
oscillator; another to govern the pitch of a second oscillator; and the third to open and close a
filter so that it tracks across the keyboard.
Unlike a passive mult, which merely splits the incoming signal and shares it across multiple
outputs (much like a Y-cable), buffered mults make electrical copies of an input voltage and
duplicate that voltage at the outputs.
Buffered mults have a few advantages over passive mults. Because buffered mults isolate their
outputs from the input, any faults or shorts present at the input will not pass through to a
connected module. Also, in a passive mult, what you connect to an output can cause a slight
