Have a Wireless system, but the Base doesn't have a wired input just-in-case? Checkout our Input Override! Under normal conditions, the Input is passed straight through to the Output jack. But plug something into the Override jack, and the override signal will be passed to the output jack instead! We've redesigned the circuit itself so the internal DIP switch is no longer necessary! It supports both mono and/or stereo automatically, just use the same cable type on all jacks! *I'm having problems with my label/sticker vendor, so depending when that is solved, yours may come with just basic function labels/no branding logo =)
