The ASM324-Xpander is a 7-jack module that can provide a 1-in/5-out split or a 1-in/3-out and a 1-in/2-out split.


The ASM324 can also be supplied with a mix of 3.5mm and 4mm jacks for sending/receiving signals to/from external equipment and other synths or even be used within a mixed-format system:


ASM324-3: All jacks are 3.5mm

ASM324-4: All jacks are 4mm

ASM324-3I/4O: The 2 [IN] jacks are 3.5mm with the [OUT] jacks being 4mm

ASM324-4I/3O: The 2 [IN] jacks are 4mm with the [OUT] jacks being 3.5mm


Inserting a jack in to the top [IN] socket will replicate the signal at all of the [OUT] jacks giving you a 1-in/5-out expansion.


Inserting a jack in to the bottom [IN] socket will replicate that signal on the bottom [OUT] jacks giving you a 1-in/2-out expansion. It will also automatically split the top section in to a 1in/3-out expansion with its [IN] signal only going to the top 3 [OUT] jacks.
