It is a good idea to put the L/R Group Master control to approximately three quarters of it’s travel which will correspond to 0db output. The I/P module level control should now be advanced to obtain a suitable reading on the bargraph display. If the ‘SOLO’ master control is turned clockwise and the ‘SOLO’ button on the input is AUX 1-4 MASTER depressed, the red LED next to the solo master control will flash and the solo signal LEVEL CONTROLS will be indicated on the bargraph meters. 12 SEGMENT BARGRAPH By plugging a balanced (stereo) jack into any or all of the four ‘AUX SEND’ jacks the DISPLAYS FOR GROUP auxiliary sends can be accessed. Turning the associated master level controlwill adjust AND SOLO LEVELS the overall level of the auxiliary send.
