Be sure to save the packing carton in case you ever have to return the unit for service. Be sure that the local power outlet matches that of the required voltage for your mixer. [. . . ] In the OFF position, all signals return to their ©American Audio® - www.

CUE MIXING CONTROL This functions allows you to monitor the Cue level as well as the Program (main output) level in your headphones. A channels Cue Level may only be monitored if the channels Cue function is selected. To select a channels cue function depress the CUE BUTTON (7) that is directly associated with the specific channel you wish to monitor. You may use the mixing function to blend both the Cue level and the Program level together. You can vary the output level to either hear more or less of either of the two levels. Sliding the Cue Mixing fader to the CUE position will allow you to hear more of the Cue level. Sliding the knob to the PGM position will allow you to hear more of the Program level (main output). You may also use the Cue Mixing Control to hear either the Cue level or the Program level exclusively. If the fader is in the full CUE position you will only hear the cue level, if the fader is in the full PGM position you will only hear the main output. This function will especially be useful for occasions when an external monitor is not available. CUE LEVEL VOLUME CONTROL This knob is used to control the headphone volume output level. MASTER VOLUME CONTROL This fader is used to control the master output level (main volume). To avoid distorted output try to maintain an average output signal level +4 dB. This fader will control the XLR-BALANCED (28) output jacks and MASTER VOLUME RCA (31) jacks. HEADPHONES JACKS This jack is used to connect your headphones to the mixer. Always be sure the CUE LEVEL VOLUME (12) is set to minimum before you put the headphones on. This jack will accept a standard 1/4" male plug or a XLR 3-pin balanced male plug. The volume output level will be controlled by the MIC 1 VOLUME CONTROL KNOB (18). BNC JACK This jack is used to supply a 12V DC signal to a gooseneck light, such as the American Audio® GNL14. FADER ASSIGN SWITCH This is a four position switch that assign a channel to the CROSSFADER (8). When a channel is assigned to the left side of the CROSSFADER (8) that channels output level will be controlled by the CROSSFADER (8). [. . . ] After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the actual cables. The connector is designed to only fit one way, so don't worry about the connectors orientation. Connect the new crossfader to the ribbon cable and replace in reverse order. ©American Audio® - www.
