Thank you for purchasing theAzden FMX-20 portable mixer. The FMX-20 has many unique
features, so please read this manual completely before using the mixer. Designed to work
with all microphones that have a low-impedance XLR output, the FMX-20 can be connected
to any video camera or audio recorder, which has XLR, or mini-jack mic/line inputs.
LOADING THE BATTERY: Make sure the mixer is turned off. Remove the battery
cover (A) by turning the screw (B) counter- clockwise until it comes off. Place the battery
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
force the battery into the compartment. If the battery does not go in easily turn it around
and try again. Replace the battery door (A) and turn the screw (B) clockwise until tight,
do not over tighten. Anew 9-VoltALKALINE battery should last for more than 6 hours.
MOUNTING OPTIONS:
1) Belt Clip (supplied): The belt clip (C) can be attached to the backside of the mixer in 3
different positions. To remove the belt clip use a Philips head screwdriver and turn the
screws (E) counterclockwise until they come off. To install the belt clip, select the desired
location and turn the screws clockwise until tight.
2) Hook & Loop (supplied): Hook & Loop can be attached to either side of the mixer and to any
adjoining flat surface (camera body, tripod, etc.) The Hook & Loop strip with the soft surface
should be attached to the mixer and the Hook & Loop strip with the rough surface should be
attached to the adjoining surface.
3) Strap (not supplied): A strap can be looped through the strap cutouts (D) on the sides
of the mixer.
CONTROLS and INPUTS/OUTPUTS
1 through 16
POWER SWITCH (1) and POWER LED (2):
To power the FMX-20 by the internal battery. Move the POWERswitch (1) to INT position.
The POWER ON LED (2) will turn green. When the battery voltage level is low the POWER
ON LED (2) will turn to RED. When the POWER ON LED (2) turns to red replace the battery
with a new 9-Volt ALKALINE battery. (see LOADING THE BATTERY above). When not
in use turn the mixer OFF to conserve battery life.
To power the FMX-20 with an external power supply. (Note:The FMX-20 does not come with
an external power supply. An optional power supply part number BC-26U is available from
the Azden parts department. Call 516-328-7500 for details. If you use a different power
supply make sure its output does not exceed 12 volts or you may damage the unit.) Move
the power switch (1) to EXT position. The POWER ON LED (2) will turn green. When not in
use turn the mixer OFF and disconnect the power supply from the mixer.
INPUT LEVEL CONTROLS for Channel 1 (3) and Channel 2 (4):
CH1 (3): Controls the input level (volume) of the microphone connected to Input CH 1 (12).
Zero is the lowest (quietest) setting, 10 is the highest (loudest). For the best possible sound
and lowest noise increase the input level control until the input LED lights occasionally.
INPUT CH 1 (12) and CH 2 (13)
CH2 (4): Controls the input level (volume) of the microphone connected to Input CH 2 (13).
Zero is the lowest (quietest) setting, 10 is the highest (loudest).For the best possible sound and
lowest noise increase the input level control until the input LED lights occasionally.
Connect the output of a microphone or wireless receiver to INPUT CH 1 (12) and/or CH 2
(13). The inputs accept a standard 3-pin male XLR connector equipped cable. Push the
connector into the input jack until it locks. To remove the connector, press the PUSH tab and
pull out the connector. For a more detailed description of how INPUT CH 1 (12) and
INPUT CH 2 (13) work see OUTPUT SELECT above.
OUTPUT LEVEL LED INDICATORS (5)
For the best sound increase the INPUT LEVEL of CH1 (3) and/or CH2 (4) so that the
corresponding PEAK LED indicator (5) flashes red occasionally during the loudest parts of
what you are recording. If the indicator does not light it means that the input (volume) level is
too low and the sound may be accompanied by background hiss. If the indicator is lit
continuously it means that the input (volume) level is too high and the sound may be distorted.
Monitor the sound with headphones and adjust the input levels for the best sound.
OUTPUT CH A (14) and CH B (15)
Connect a cable from OUTPUT CH A (14) and/or CH B (15) to the mic or line input of your
video camera or audio recorder. The outputs accept a standard 3-pin female XLR connector
equipped cable. Push the cable connector into the output jack until it locks, and to remove the
connector press the release tab on the connector and pull out. For a more detailed
description on how OUTPUT CH A (14) and CH B (15) work see OUTPUT SELECT
above.
OUTPUT SELECT CH A (6) and CH B (7)
By setting the OUTPUT SELECT switch (6) and/or (7) to L the sound of any microphone
plugged into the corresponding INPUT CH1 (12) and/or CH2 (13) will be sent to OUTPUT
CH L (14). If using the UNBALANCED OUTPUT (16) the sound of this microphone will be
sent to the left channel.
UNBALANCED OUTPUT (16)
This output is stereo (dual-channel). It is recommended to use a stereo-to-stereo mini-
cable (not supplied) from the UNBALANCED OUTPUT (16) to the mic or line input of your
video camera or audio recorder. The UNBALANCE OUTPUT (16) is designed for video
cameras or audio recorders, which have mini-jack microphone or line inputs. Because the
FMX-20 has low-impedance XLR inputs and a mini-plug output, users of mini DV cameras
that have mini-plug microphone inputs can now use high-quality microphones with XLR
outputs. For a more detailed description on how the UNBALANCED OUTPUT (16)
works see OUTPUT SELECT above.
By setting the OUTPUT SELECT switch (6) and/or (7) to C the sound of any microphone
plugged into the corresponding INPUT CH1 (12) and/or CH2 (13) will be sent to OUTPUT
CH L (14) and OUTPUT CH R (15). If using the UNBALANCED OUTPUT (16) the sound
of this microphone will be sent to the left and right channels.
By setting the OUTPUT SELECT switch (6) and/or (7) to R the sound of any microphone
plugged into the corresponding INPUT CH1 (12) and/or CH2 (13) will be sent to OUTPUT
CH R (15). If using the UNBALANCED OUTPUT (16) the sound of this microphone will be
sent to the right channel.
DC 12V Input (17)
For external powering of the mixer connect a power supply to this input. Maximum rating
of the power supply should not exceed 12 volts, 350mA.
MONITOR CONTROL (11) and MONITOR OUTPUT (10)
The MONITOR control(11)adjuststhevolumelevelofheadphonesconnectedtotheMONITOR
output (10). Zero is the lowest (quietest) setting, 10 is the highest (loudest).
MONITOR SELECTOR SWITCH (#9)
Normally, set the MONITOR selector (9) to position L/R. In the L/Rposition you will monitor
the sound of all connected microphones using either stereo or mono headphones. If you only
want to hear the output from CH L, use stereo headphones and set the switch to position L.
Or, if you only want to hear the output from CH R, use stereo headphones and set the switch
to position R.
LIMITER SWITCH (8)
After setting the Input Levels, turn this switch to ON. The limiter circuit reduces possible
overload distortion from very loud sound levels without affecting normal sound levels. If you
prefer the overall sound quality of the mixer without the limiter circuit engaged leave the switch
OFF.
