FMX22D
Battery Microphone Amplifiers / Mixer
The FMX22D is a 2 channel studio grade microphone mixer designed for remote or field mixing in video, film, broadcast or professional recording applications. The compact and lightweight mixer boasts an impressive feature set starting with 2 transformer balanced XLR microphone inputs and stereo (L/R) XLR outputs. Separate stereo tape output and tape return input are provided, both feature 1/8" (3.5 mm) mini stereo jacks. The mixer supplies +15V and +48V phantom power and a 1/4" TRS phone/headphone monitor output allows monitoring of main and tape return inputs. Both channels feature user switchable, two-stage limiting for control over signal overload and distortion. The low-cut filter removes low frequency noise caused by wind and proximity effect. Also provided is an internal test tone oscillator and slate microphone for signal calibration. The FMX22D is powered via 2 AA alkaline batteries or external DC power source.
