The Azden FMX-22 is a professional-grade, portable two-channel mixer designed for field audio production, electronic news gathering (ENG), and integration with video cameras. This compact and rugged mixer provides essential mixing capabilities for videographers and sound recordists who need to combine and control two microphone or line-level sources before sending a clean signal to a camera or recorder. Its primary feature is two balanced XLR inputs, each with individual gain control, peak level indicators, and pan knobs, allowing for precise balancing of two audio sources—such as a lavalier and a shotgun microphone—into a stereo or mono output. The mixer is built for durability in field conditions, with a metal chassis and the ability to be powered by internal AA batteries or an external DC source, ensuring reliability during extended shoots away from AC power.

A key aspect of the FMX-22 is its professional output options. It includes both a standard 3-pin XLR output for connecting to pro audio gear and a dedicated 5-pin XLR output that provides a dual-system feed, sending the mixed output on pins 2 and 3 while passing a clean, unaffected signal from Input 1 directly to the camera on pin 1. This is particularly valuable for backup recording or when the camera operator needs a separate ISO (isolated) track. The mixer also features a headphone output with volume control for real-time monitoring, a tone generator for level setting, and a slate microphone for adding verbal cues to the recording. Its compact size allows it to be easily mounted on a camera via an accessory shoe or carried on a strap.

Designed for intuitive operation, the FMX-22 requires minimal setup, making it accessible for both seasoned audio engineers and solo shooters. The inclusion of phantom power (+48V) on both inputs enables the use of professional condenser microphones directly. By offering robust construction, flexible powering, critical monitoring features, and professional dual-output functionality in a portable package, the Azden FMX-22 serves as a vital tool for enhancing audio quality and workflow in documentary filmmaking, news coverage, and event videography.
