INTRODUCTION
Thank you for purchasing Azden's FMX-42 4-channel portable mixer. The FMX-42
was designed to work with most microphones that have a low-impedance XLR output
or line-level devices. Its output can be connected to virtually any video camera or
audio recorder, which has XLR or mini-connector mic/line inputs.
It is very important to read and understand this manual completely before use. Keep
this manual for future reference.
SAFETY INSTRUCTIONS
・When connecting/disconnecting cables, and/or changing the PHANTOM power
settings or INPUT LEVEL settings, make certain to turn the input LEVEL control
knobs to zero or to turn the POWER switch OFF.
・When the PHANTOM DC48V power is not needed, make sure the PHANTOM switch
is in OFF position.
・Before turning the PHANTOM DC48V switch ON, make sure your condenser
microphone is designed to handle 48VDC or the microphone may be damaged.
Check the microphone's user manual or with the manufacturer of your microphone.
INSTALLING BATTERIES
Make sure that the POWER switch ⑯ is OFF. Remove the battery cover by pressing
the clip in and then lifting up the cover. Install 6 fresh"AA"alkaline batteries following
the polarity diagram inside the battery compartment. Do not force the batteries.
After all 6 batteries are properly installed, replace the battery cover and move the
POWER switch to the"ON"position. The POWER indicator LED ① in the front panel
will turn green.
CAUTION
・Do not use other batteries than "AA" alkaline batteries. Do not mix fresh batteries
with used batteries.
・Remove the batteries if the mixer will not be used for a long period of time to prevent
battery fluid leak.
EXTERNAL POWER
The FMX-42 can be powered from an external power supply using a 12V AC adaptor
(not included*). When the FMX-42 is connected to an active 110VAC through an AC
adaptor and the POWER switch is turned ON, the batteries will be automatically
disconnected.
*An optional AC adaptor, part number BC-27H, is available. Call Azden for details.
BALLISTIC NYLON CASE
The FMX-42 is supplied with a ballistic nylon case. Place the mixer in the case and
adjust the neck strap to achieve the most comfortable position. For additional support
and comfort, if desired, a back harness (not supplied) can be secured to the metal rings
on the case.
