Ok im looking at pic this cable 1/4 jack isnt stereo correct it is mono?

This isn't a "stereo" vs. "mono" connection. All amplifier inputs are mono, be they pro, commercial or consumer. Rather, it's "balanced" vs. unbalanced." It just so happens both types can be done with 1/4" connectors. The "stereo" plug (aka TRS or "tip, ring, sleeve") would be used for a balanced signal, with the three connection points as signal (+), signal (-) and shield. Notice this is not stereo, because there is no "signal left and right." The "mono" plug (aka TS or "tip, sleeve") is used for unbalanced, where the two connection points are signal (+), and combined shield/signal (-).

It's just part of the confusion we get because the audio industry, both consumer and professional, has historically (and foolishly) had a penchant for using the same type of connector for a variety applications, instead of dedicating particular connectors to specific applications like they should have. For instance, further adding to the confusion, many pro audio amps also use the 1/4" connectors for speaker outputs, too. So you end up having cables with the same connectors for both the signal inputs and speaker ouputs.
