INTRODUCTION
1
Congratulations on your purchase of Azden's FMX-42a/FMX-42u, 4 channel portable mixer. Both the FMX-42a
and FMX-42u were designed to work with low-impedance XLR microphones and/or line-level devices. Their
output can be connected to virtually any video camera or audio recorder which has XLR or mini-connector
mic/line inputs.
The FMX-42a model is equipped with a camera return input/output to allow the user to simultaneously send
and receive an audio signal to/from a camera. This same output may also "be used an auxiliary output to send
to a second camera or audio recorder. Specialty cables (sold separately) a more details about using the
camera return on page 5.
The FMX-42u model is equipped with a USB Digital Signal Output, allowing the user to send a stereo digital
audio signal to a computer, smart-phone or tablet device for recording. A separate USB cable will be required
(not included) to use. See more details about using the USB Output on pages 6 & 7.
It is very important to read and understand this manual completely before use. Keep this manual for future
reference.

SAFETY INTRODUCTION
• 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 the OFF position.
• Before turning the PHANTOM DC48V switch ON, make sure your microphone is designed to handle 48V DC
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 ⑯is 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 ①in the front panel will turn
green.
CAUTION
• Do not use batteries other 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 mixer can be powered from an external power supply using a 12V AC adapter (not included*). When the
mixer is connected to an active 110VAC through an AC adapter and the POWER switch is turned ON, the
batteries will be automatically disconnected.
*An optional AC adapter is available. Contact Azden or an Azden dealer for details.
BALLISTIC NYLON CASE
The mixer 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.

INTRODUCTION
①POWER Indicator
When the POWER switch ⑯is ON, the LED will turn GREEN. When the battery voltage level becomes too low
for proper operation, the LED will turn RED. When this happens, replace the batteries with fresh "AA" alkaline
batteries.
②Channel 1, 2, 3 & 4 Input LEVEL Controls
Each knob controls the input volume of the microphone connected to the corresponding INPUT
⑬. Zero is the lowest (quietest) setting while 10 is the highest (loudest). For the best sound with the lowest
possible noise, increase the input level control until the corresponding VU Meter ⑧peaks at 0 dB.
③Channel 1, 2, 3 & 4 PAN Controls
Each channel of the mixer has an adjustable PAN control (the outer-ring at the base of the Input LEVEL
control ②). When the PAN Control is in the center position, an equal amount of sound will come from
OUTPUT L ⑰and OUTPUT R ⑱for any microphone or line level device connected to the corresponding
INPUT ⑬. Turning the PAN control counter-clockwise will decrease the sound output in the Right channel.
Turning the PAN control clockwise will decrease the sound output in the Left channel.
④MASTER Level Control
The MASTER knob controls the overall volume of all connected sources (microphones and/or line- level
devices). For the best sound with the lowest possible noise, try to keep this control set at its midpoint while
maintaining the VU Meters ⑧at the 0 dB range with the input LEVEL controls ②.
⑤Channel 1, 2, 3 & 4 LIMITER Switch
Each INPUT channel ⑬has a switchable LIMITER. After setting the input LEVEL ②, turn this switch to ON. The
LIMITER circuit acts as a safety and reduces the possibility of overload distortion from very loud sounds
without aecting normal sound volume. If you prefer the overall sound quality of the mixer without the
LIMITER circuit engaged, leave the switch OFF.
⑥Channel 1, 2, 3 & 4 HPF (High Pass Filter) Switch
Each INPUT channel ⑬has a switchable High Pass (= Low Cut) Filter. When turned on, it will cut input
frequencies lower than 100Hz. This filter is useful for removing unwanted low frequencies, such as wind and
air-conditioning noise. For most noisy recording environments, engaging the High Pass Filter will improve
overall sound quality.
⑦Input PEAK Level Indicators
Each INPUT channel has 2 PEAK Level Indicators on the left side of the LEVEL control knob②.These Indicators
are provided to help set precise input LEVEL adjustments. The lower LED indicates the level of the input
electronically prior to the LEVEL control while the upper LED indicates the level electronically after the LEVEL
control. The lower LED lighting RED indicates that the item connected to the mixer's INPUT ⑬has a signal
that is too high and should be reduced either by changing the INPUT LEVEL switch ⑭setting or at the device
itself. The upper LED should only light RED occasionally. If this LED stays lit continuously, lower the input
LEVEL ②and/or change your INPUT LEVEL ⑭settings. These LEDs help reduce signal overload and
distortion.
⑧VU Meters L and R
The VU Meters will show either the output volume level of LINE OUT ⑰&⑱or input volume level of CAMERA
