New and improved, the Azden FMX-22 portable two-channel field mixer replaces the FMX-20, now using the same circuit topology as the more expensive Azden mixers. With improved signal to noise ratio and wider frequency response the new FMX-22 is designed for the demanding needs of professional videographers. This compact (2.2 x 5.7 x 4.7 inches), all-metal, battery-operated mixer can be attached directly to any flat surface with supplied hook-and-loop fastener. The FMX-22 connects easily to the video camera's MIC input via the mixer's balanced L and R XLR outputs or its unbalanced 3.5mm stereo mini-jack output. It features two XLR microphone inputs. Each mic input has switchable phantom power (48V DC), two input level settings (Hi / Lo), output level volume control (0 - 10) and an individual switchable limiter. The FMX-22 also features a Master Level Control that controls the overall volume level of all connected sources.

Channel Output Selectors let you assign the output of each input channel between Left, Center and Right. The FMX-22 also features a five-step LED array for signal monitoring and a 1/4-inch monitor headphone jack with level control. The Azden FMX-22 operates on four AA batteries, with a 12V input for external power. The Azden BC-27 AC adaptor is an available optional accessory.

Azden FMX-22 Key Features

Two Balanced XLR Inputs With Individual Output Level Controls

Controls the input level of the microphone connected to each input channel. Zero is the lowest (quietest) setting, 10 is the highest (loudest).

Switchable Phantom Power For Each Input

Each mic input has available phantom power (48V DC) with On/Off switch.

Configurable Output

Channel 1 and 2 Output Selectors let you assign the output of each input channel between Left, Center and Right. One microphone can be mixed to both outputs as well as either single output while two microphones can be mixed to either single output or mixed together to both outputs. When mixing two mics, you can also output the audio from one microphone to one channel while outputting the audio from both mics to the other channel.

Two XLR Outputs, One Mini Jack Output

The FMX-22 features two balanced XLR mic/line switchable outputs. Connect a cable from Output CH A and/or CH B to the mic or line input of your video camera or audio recorder. These outputs accept a standard 3-pin female XLR connector equipped cable.

The Unbalanced Output (mini-jack) is designed for video cameras or audio recorders which have mini-jack microphone or line inputs. Because the FMX-22 has low-impedance XLR inputs and a mini-plug output, users of cameras that have mini-plug microphone inputs can now use high-quality microphones with XLR outputs. The Unbalanced Output output is stereo (dual-channel). It is recommended to use a stereo-to-stereo mini cable (not supplied) from the Unbalanced Output to the mic or line input of your video camera or audio recorder.

Five-Step Output Level Indicator LED Arrays For Easy Signal Monitoring

These indicators show the output volume level of the L and R outputs. When the indicators show red, you can reduce the volume level by turning the input level control knobs or the master level control knob.

Runs on Ordinary AA atteries

The FMX-22 operates for 15 hours of continuous use on four AA alkaline batteries (not supplied).

12V DC Input

The FMX-22 can be run on four AA battery power or plug an optional AC adapter into the 12 volt input.

Built-in Switchable Input Limiter And Hi / Lo Input Level Settings For Each Input Channel

The limiter can be switched on to protect against peak distortion on each due to overload. Each mic input has two input level settings (Hi / Lo).

Headphone Output (Stereo or Mono) With Level Control

The FMX-22 has a 1/4-inch (6.3mm) monitor headphone jack with level control. You can connect a stereo or mono headphone to the Monitor output. A Monitor control adjusts the volume level of headphones connected to the Monitor output.

POWER On/Off/Low Battery LED Indicator

When the POWER switch is turned ON, the POWER LED will turn green to indicate the power is on and the battery is charged. When the battery voltage level is low, the POWER LED will turn red.
