FX44 Mixer Detailed Control Descriptions Section 3 15b) Power Cord Connector Fuse The A.C. line fuse is a protective safety feature. If your console should have an electrical malfunction, this fuse will protect the console from further damage. You should never attempt to increase the value of this fuse from the value listed on the back of the chassis. To do so could cause damage to your console. Fuse Replacement: The fuse is located inside the Power Cord Connector. With the power cord removed, you will notice a notch just inside the roof of the connector. Insert a straight edge screwdriver into this notch and gently pry it forward, using the bottom of the plug to push against. A 'top drawer' will slide forward. Remove this drawer. You will notice the drawer is made of a box in front and a clip containing a fuse behind it. Replace the fuse in the clip with a fuse of the appropriate value for your console(See below). Replacing the drawer in the connector will automatically connect the fuse. An extra fuse may be stored in the forward box. Note: Be sure if you are ever in need of running your console from the A.C. power produced by a generator, that you use a properly "regulated" generator that will eliminate A.C. power surges. Such surges could damage your console and result in blown fuses. FUSE VALUES FOR DIFFERENT MODELS The fuse values for the different models are printed on the rear panel near the Power Connector. Different fuses are needed for 120V and 240V A.C. power supplies. Be sure to check the value of the fuse when you start using a different power source. If you are unfamiliar with international electrical values, it is best to ask the house manager which voltage is supplied.

To determine if the switch is properly selected, look at the switch (on the switch is printed the voltage the switch is selected to). The voltage you read from the switch is the voltage the amplifier is set to accommodate. 17) Fan Cooling (Powered Models Only) The powered FX-44 series console feature a quiet low speed cooling fan located in the rear control panel. This provides optimum cooling for the unit under any adverse loading conditions. Do not block the rear vent area. 3-14
