the 'small' SP-BOXX, too backs on proven components from HICON and NEUTRIK - teamed with SYSBOXX-inside and the same robust external design.
Here again we habe three NL4 sockets for each channel pair: one fully wired (1+/1-/2+/2-) and two partially wired (1+/1-).
As multipins we took the 8-pole HICON PA-COM (compatible with the widespread CA-COM 8-pole) or the NEUTRIK NL8.
The SP-BOXX is available with multipin input pls input and link-through multipin.
