22,27. GRAPHIC EQ�S: These seven band graphic equalizers allow customization and shaping of the output signals to match room acoustics and enhance the sound. Use the selector switch (#25) to determine where the equalization will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals. 23,28. LED METERS/LIMITER INDICATORS: These LED meters monitor the output signal levels for either the main and monitor output signals, or the main 1 and main 2 output signals (dependent on the setting of the selector switch, #25). The red LED�s illuminate when the internal limiter is engaged to prevent the signal from being clipped. (Clipping results in overdrive distortion and should be avoided.) If the limiter LED�s flash continuously or remain on constantly during use, reduce the output signal levels until they flash only on strong signal peaks. 24,29. EFFECTS RETURNS: Use these controls to adjust the magnitude of the effects applied to the output signals. Use the selector switch (#25) to determine where the effects will be applied: either to the main and monitor output signals, or to the main 1 and main 2 output signals. 25. MAIN/MONITOR / MAIN1/MAIN 2: Use this switch to select whether the graphic EQ�s, LED meters, and master level controls are assigned to the Main and Monitor outputs (switch in the out position) or to the Main 1 and Main 2 outputs (switch depressed. When this switch is in the out position, the Main/Main 1 graphic EQ (#27) controls the signal to power amp #1, the output of which

is connected to the Main Output jack (#44). Also, the Monitor/Main 2 graphic EQ (#22) controls the signal to power amp #2, the output of which is connected to the Monitor Output jack (#43). When this switch is depressed, the Main/Main 1 graphic EQ (#27) controls the signal to power amp #1, the output of which is connected to the Main 1 Speaker Output jacks (#46). Also, the Monitor/Main 2 graphic EQ (#22) controls the signal to power amp #2, the output of which is connected to the Main 2 Speaker Output jacks (#46). 30. EFFECTS SEND: Use this control to set the overall signal level sent to the internal DSP or external effects (if used). 31. AUX IN: Use this control to set the input signal level of the aux in jack (#40). 32. TAPE IN: Use this control to set the input signal level of the tape in jacks (#41). 34. POWER LED: This LED illuminates when the mixer is on. 35. PHANTOM +48V: This switch, when depressed, applies +48 volts DC to pins 2 and 3 of each channel�s XLR input jacks. This allows use of microphones which require a source of phantom power for proper operation. (Mics not requiring phantom power will not be affected by the presence of the DC voltage.) The adjacent LED illuminates when the phantom power is on. (continued...�������� >)
