How do I connect up my JCM900 Series Head and a single Mono/Stereo 1960 Series Cab?
First, make sure the amplifier is off then set the 1960 to Mono (Fig. 5.1) and connect a speaker cable to either of the JCM900’s parallel loudspeaker outputs (Fig. 5.2). Connect the other end of the speaker cable to the 1960’s 16 Ohm input (Fig. 5.3). Now set the JCM900’s impedance selector to 16 Ohms (Fig. 5.4).
