Thank you for purchasing the Azden 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) counterclockwise 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. A new 9-Volt ALKALINE 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.

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.

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 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.

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.

MONITOR CONTROL (11) and MONITOR OUTPUT (10)

The MONITOR control (11) adjusts the volume level of headphones connected to the MONITOR 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/R position 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.

INPUT CH 1 (12) and CH 2 (13)

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 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.

UNBALANCED OUTPUT (16)

This output is stereo (dual-channel). It is recommended to use a stereo-to-stereo minicable (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.

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.

Frequently asked questions

Turn the mixer off, remove the battery cover by turning the screw counter-clockwise. Place the battery strap around a new 9-Volt ALKALINE battery and insert it, following the polarity diagram. Replace the cover and tighten the screw clockwise.

The POWER ON LED turning red indicates that the battery voltage level is low and you should replace the 9-Volt ALKALINE battery with a new one.

Increase the input level control until the corresponding PEAK LED indicator (5) flashes red occasionally during the loudest parts of your recording. If it doesn't light, the level is too low; if it's continuously lit, the level is too high and may cause distortion.

After setting input levels, turning the Limiter switch to ON reduces possible overload distortion from very loud sound levels without affecting normal sound levels. If you prefer the sound without it, leave the switch OFF.

Yes, you can power it externally by moving the power switch to EXT and connecting an optional BC-26U power supply (or a compatible supply not exceeding 12 volts) to the DC 12V Input (17).
