Speakon Outputs
The Speakon connectors offer quick, reliable connection and disconnection of the speakers.
Although more expensive than banana or spade-lug style speaker cable termination, the speed,
convenience, and reliability make Speakon use popular with portable and live sound setups.
The Speakons are wired:

Four conductor cable may be used for carrying both of the output channels with a single cable. Signal
splitting required at loudspeaker end of cable.

one for CH2.
