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.

FRONT CONTROL PANEL
①. POWER Indicator
When the POWER switch ⑯ is 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.

②. Channel 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 ⑧ peaks at 0 dB.

③. Channel 1, 2, 3 & 4 PAN Controls
Each channel of the FMX-42 has an adjustable PAN control (the outer-rim 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 ⑰ and OUTPUT R ⑱ for any
microphone or line-level input connected to the corresponding INPUT ⑬. Moving
the PAN control left will decrease the sound output in the Right channel. Moving the
PAN control right will decrease the sound output in the Left channel.

④. MASTER 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 ⑧
at the 0 dB range with the input LEVEL controls ②.

⑤. Channel 1, 2, 3 & 4 LIMITER Switch
Each INPUT channel ⑬ has 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 affecting normal
sound volume. If you prefer the overall sound quality of the mixer without the
LIMITER circuit engaged, leave the switch OFF.

⑥. Channel 1, 2, 3 & 4 HPF (High Pass Filter) Switch
Each INPUT channel ⑬ has a switchable High Pass (= Low Cut) Filter. When turned
on, it will cut input signals lower than 100Hz. This filter is useful for removing
unwanted low frequencies, such as wind and air-conditioning noise. For most
applications, engaging the High Pass Filter will improve overall sound quality.

⑦. Input PEAK Level Indicators
Each INPUT channel has 2 PEAK Level Indicators on the left side of the LEVEL
control knob ②.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 ⑬ has a signal that is too high and should be reduced either by changing the
INPUT LEVEL switch ⑭ setting or at the device itself. The upper LED should only
light RED occasionally. If this LED stays lit continuously, lower the input LEVEL ②
and/or change your INPUT LEVEL ⑭ settings. These LEDs help reduce signal
overload and distortion.

⑧.VU Meters L and R
The VU Meters will show the output volume level of LINE OUT ⑰&⑱. For the best

⑯.POWER Switch
⑰.& ⑱.OUTPUT Connector L and R

Connect a cable from OUTPUT L and/or R to the microphone or line input of your
video camera or audio recorder. These outputs accept a standard 3-pin female XLR
connector. Push the XLR connector into the OUTPUT jack until it locks. To remove,
press the release tab on the XLR connector and pull the connector out.

⑲.STEREO Mini-Connector Output
The STEREO mini-connector (3.5mm) output is designed for video cameras or audio
recorders with mini-connector microphone-level inputs. This output is stereo
(dual-channel) and unbalanced. The standard output level is fixed at -36 dBu. It is
recommended to use a stereo-to-stereo mini cable (not supplied) from the STEREO
mini-connector output to the input of your video camera or audio recorder. Because
the FMX-42 is equipped with low-impedance XLR inputs and a mini-connector output,
users of mini DV cameras with mini-connector microphone inputs can now use high­ quality microphones with XLR outputs.

⑳.LEVEL Selector
Select the OUTPUT ⑰&⑱ LEVEL that is best suited for your video camera or audio
recorder. The +4 dBu setting is for line-level audio inputs and the -36 dBu setting is
for microphone-level audio input.

⑳.Monitor PHONES Output Jack ／ A 6.3mm (1/4") jack for headphones.
⑳.LEVEL Volume Control

Controls the volume level of the monitor PHONES output ⑳. Zero is the lowest
(quietest) setting and 10 is the highest (loudest).

⑳.METER ILLUM(ination) Switch
Turn this switch ON to light up the VU Meters⑧.

⑳.DC IN Connector
For external powering of the mixer, connect a 12V AC adaptor to this input. It is a
4-pin Hirose connector and an optional AC adaptor, part number BC-27, is available.
Call Azden for details.
Maximum rating of the power supply must not exceed 12 volts DC, 350mA.

sound, while keeping the MASTER control ④ at its midpoint, increase or decrease
each channel's LEVEL control ② until the L and/or R VU Meter peaks at 0 dB. If
the LEVEL is set too low, sound may be accompanied by background hiss. If the
LEVEL is set too high, the sound may be distorted. Monitor the sound with
headphones and adjust the LEVEL for the best sound. An OUTPUT PEAK Indicator
LED ⑨ will light RED if your overall levels are set too high.

⑨.OUTPUT PEAK Indicators
These indicators monitor the LINE OUT outputs. When the overall levels are set too
high, the LEDs will light RED. Adjust the INPUT LEVEL controls ② and/or the
MASTER level control ④ accordingly.

⑩.SLATE MIC
Press and hold this button to engage the SLATE MIC. The SLATE MIC is used to
pick up audio at the mixer's location and is not intended for serious audio recording.
It is however, very useful for notating scenes or other on-location documentation.

⑪.1 kHz TONE
Press and hold this button to generate the 1 kHz tone. This output tone is used to set
the recording levels of your video camera or audio recorder to their optimum level.
While generating the 1 kHz tone, set the recording levels of your video camera or
audio recorder to the specified level as recommended by the manufacturers. The
signal is generated at +4 dBu.

MIC LO → Standard: -58 dBu → Maximum: -15 dBu (2 kΩ)

⑮.PHANTOM DC48V Switch
Each channel of the FMX-42a has its own PHANTOM DC48V power setting. When
using a dynamic microphone, be sure to turn the corresponding PHANTOM DC48V
switch to the OFF position. When using a condenser microphone that requires 48V
DC external power, turn the corresponding PHANTOM DC48V switch to the ON
position. The PHANTOM DC48V only operates in the MIC HI or MIC LO INPUT
LEVEL setting ⑭.

CAUTION

・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.
・Before turning the PHANTOM DC48V ON/OFF, be sure to turn the Input LEVEL
controls ② to zero.
・When the PHANTOM DC48V power is not needed, make sure the PHANTOM switch
is in OFF position.
