SubMatch Cable is a proprietary hybrid power-and-audio connection that links the Sub1 or Sub2 powered bass module to the L1 Pro32 portable line array. It also enables daisy-chaining a second Sub1 or Sub2 within the same system. The cable uses thick 12‑gauge conductors with a spring-loaded locking collar for a secure fit. A single SubMatch cable is included with the L1 Pro32; additional cables are sold separately.
