The Azden FMX-22 is a compact, professional two-channel portable mixer designed to provide versatile audio mixing and enhancement for on-location video production, field recording, and live streaming applications. Its core functionality centers on two balanced XLR microphone inputs, each equipped with a high-quality preamplifier, individual gain control, and a three-band EQ (low, mid, high) for tailoring the sound of each source. This allows videographers and journalists to blend and optimize two discrete audio sources—such as a lavalier microphone on a subject and a shotgun microphone on the camera, or two interview subjects—into a single, balanced stereo or mono output. The mixer is particularly valuable for DSLR and mirrorless camera users, as it delivers clean, controlled audio with proper gain staging that far surpasses the often noisy and limited preamps found in consumer cameras.

Beyond basic mixing, the FMX-22 incorporates several professional features to enhance audio quality and usability in the field. Each channel includes a peak LED indicator to prevent clipping, a low-cut filter to reduce rumble and wind noise, and independent level faders for precise balance control. The mixer also integrates a built-in limiter on the final output to protect against sudden audio spikes that could distort the recording. For monitoring, it provides a stereo headphone output with its own dedicated volume control, allowing the operator to audition the mix privately. The unit is powered by a single 9V battery, making it entirely self-contained and highly portable for run-and-gun shooting scenarios where access to AC power is not available.

Constructed with a durable metal chassis, the FMX-22 is built to withstand the rigors of field use. Its small form factor allows it to be easily mounted to a camera rig or placed in a gear bag. The output is delivered via a standard 3.5mm stereo mini-jack, which connects directly to the microphone input of most cameras and portable recorders. By offering two channels of professional-grade preamp control, EQ, and limiting in a battery-powered, handheld device, the Azden FMX-22 empowers solo shooters and small crews to capture broadcast-quality, multi-source audio with simplicity and reliability, directly improving the production value of their video content.
