ThankyouforpurchasingtheAzdenFMX-20portable mixer. TheFMX-20hasmanyunique
features,sopleasereadthismanualcompletelybeforeusingthemixer. Designedtowork
withallmicrophonesthathavealow-impedanceXLRoutput,theFMX-20canbeconnected
toanyvideocameraoraudiorecorder,whichhasXLR,ormini-jackmic/lineinputs.
LOADING THE BATTERY: Make sure the mixer is turned off. Remove the battery
cover(A) byturning thescrew(B)counter-clockwiseuntilitcomesoff. Placethebattery
strap (located in the battery compartment) around a new 9-Volt ALKALINE battery and
insert it into the battery compartment. Be sure to follow the polarity diagram inside the
battery compartment. If the polarity is correct the battery should go in easily. Do not
forcethebatteryintothecompartment. If the battery does notgoineasilyturnitaround
and try again. Replace the battery door (A) and turn the screw (B) clockwise until tight,
donotovertighten. Anew9-VoltALKALINEbatteryshouldlastformorethan6hours.
MOUNTING OPTIONS:
1)BeltClip(supplied): The belt clip(C) canbeattached to thebacksideofthemixer in 3
different positions. To remove the belt clip use a Philips head screwdriver and turn the
screws(E) counterclockwiseuntiltheycomeoff. Toinstallthebeltclip,selectthedesired
location and turn the screws clockwise until tight.
2)Hook&Loop(supplied):Hook&Loopcanbeattachedtoeithersideofthemixerandtoany
adjoiningflatsurface(camerabody,tripod,etc.) TheHook&Loopstripwiththesoftsurface
shouldbeattachedtothemixerandtheHook&Loop stripwiththeroughsurfaceshouldbe

3)Strap(notsupplied):Astrap can be looped throughthestrapcutouts(D)onthe sides
of the mixer.
