A question in G4+ Posted August 24, 2018 · Report reply Just now, Adamw said: Need a bit more info. Is it a G4+? Is it a wire-in or plug-in? It would be pretty difficult for an end user to test most inputs and outputs without being connected to a running engine. Its G4 but i wrote it here coz the old section seems to get less attention. Its a wire-in. So i got it right, ill have to connect it.
