This Module is currently available.
trunk lines and multiples
6HP 8-channel trunk lines and two 4-way multiples
This is a passive module (no power supply required).
The 8 trunk lines connect to 8 rear facing 3.5mm jacks. This enables two of these modules to be used in a large rack so that 8 long internal patch cables can be used to link one end of a large synth to the other end to prevent lots of long cables draping across the front panel. Alternatively the 8 jacks can be connected to a rear panel connector for sending out and bringing in signals to and from outboard equipment.
The two 4-way multiples are linked so they can give a 7-way multiple if required.
Note: the module depth is 26mm but you should allow 60mm for rear entry patch leads.
