MAIN MIC - The main mic connector uses a combo plug that allows you to connect either a 1/4” unbalanced jack or by a standard 3-pin XLR balanced connector. The main mic also has an indepen- dent volume control. When feedback occurs when using the mic, try lowering the level this may reduce the feedback. Always leave the mic level to it’s minimum level when not in use. Note: We recommend that you use a 500-600ohm microphone for the best sound quality.

When the fader is in the full left position (channel 1), the output signal of channel one will be controlled by the master volume level. The same fundamentals will apply for chan- nel two. Sliding the fader from one position to another will vary the output signals of channels one and two respectively. When the crossfader is set in the center position, the output signals of both the channels one and channels two will be even. 14. CROSSFADER CURVE ADJUSTMENT - This rotary knob is used to change the way the cross- fader will operate. The crossfader can operate in different modes, “NORMAL CURVE”, “QUICK CURVE” or any variation of the two. (Quick Curve is usually used for scratching).

Page 20: Cleaning
4. Always be sure to dry all parts completely before plugging the mixer in. Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, dust, dew). 14MXR CROSS FADER REPLACEMENT The crossfader is “Hot Swapable” which means it may be replaced at any time, even when power is applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any other model fader may seriously damage your mixer. Replacing the Crossfader: 1. Disconnect the mixers main power supply 2. Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws that hold the crossfader in place. 3. Gently remove the crossfader from its seated position. You may need to wiggle the crossfader slightly to remove it. 4. 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 connec tors orientation. 5. Connect the new crossfader to the ribbon cable and replace in reverse order. American Audio - www.americanaudio.us - 14MXR Instruction Manual Page 20 © ®... -
