The FMX-22 portable field mixer provides users with a portable, lightweight production solution for industry professionals working in a diverse range of environments and studios. Thanks to an extended battery life and rugged design, the FMX-22 is perfectly equipped for use as an on-location audio mixer, providing power and performance in situations that may be too hazardous for conventional studio equipment. With a 20 Hz - 20 kHz frequency response range and dual XLR inputs, the FMX-22 is an excellent addition to the travelling audio professional’s hardware configuration.
