AJH Synth MiniMod Gain Switch Expander and Multiple

We have had quite a few customers asking if we can make the gain jumpers on the MiniMod VCF and VCA modules accessible from the front panel, so here is the solution! This compact 2HP module has two switches which connect to the gain jumpers on the VCA and VCF.

Switch “up” is the same as having the gain jumper in place, switch “down” is the same as removing the jumper, and gives higher gain. Using these switches gives a similar effect to the old "headphone out to external input" trick on the original Model D but with a much wider overdrive range, particularly from the VCA. We have also included a six way passive multi.

Available with with either a Silver or Black fascia panel.

To fit the Gain Switch Multi simply install it in close proximity to both the MiniMod VCA and VCF modules. Remove the gain jumpers from the rear of the VCA and VCF and fit the appropriately labelled connector to the two pin gain header on the VCA or VCF pcb. Keep the Jumper caps that are removed in case you wish to remove the Gain Switch Multi and reverse the process in future.

Please note that the header cable connector can be fitted either way around to the pin header on the VCA or VCF module itself, connection polarity is not important here. The connecting cables from the Gain Switch Multi to the VCF and VCA are deliberately kept short to reduce / prevent crosstalk from other modules and electrical items.
