Plug the guitar lead into the jack socket in the center of the combination input socket (5) on the channel of your choice. Turn up the volume control on your guitar to about halfway, and then gradually turn up the Main Volume control (6) until you hear the guitar signal appearing in the loudspeakers.You should also see activiity on the Main Output meter (7).

Two of these channels are equipped with RCA/Phono connectors (Channel 5 and 6) (12) and two with Jack connectors (Channels 7 and 8) (13).

Turn up the Main Master Volume control (1) to about halfway, and then turn up the Main Volume control (6) on the chosen channel until you hear the signal appearing in the loudspeakers.
