This is the Buffered and Passive Multiples module by CTorp. My only modification was to overlay the front panel with a design more compatible with my other modules’ style.
This design has 100k input impedance, so is not suitable for use with 1 V/oct signals that come through out-of-loop 1k resistors. For those a higher impedance module, such as a follower-based multiple , may be a better choice.
