How do I connect up my JCM900 Series Head and two Mono/Stereo 1960 Series Cab?
First, make sure the amplifier is off then set both cabinets to Mono (Fig. 6.1) and connect a speaker cable to either of the JCM900’s Parallel loudspeaker outputs (Fig. 6.2). Connect the other end of the speaker cable to the first 1960’s 16 Ohm input (Fig. 6.3). Now connect a second speaker cable to the JCM900’s remaining parallel loudspeaker output (Fig. 6.4). Connect the other end of this cable to the second 1960’s 16 Ohm input (Fig. 6.5). Lastly set the JCM900’s impedance selector to 8 Ohms (Fig. 6.6).
