  • Azden FMX-42 Portable Mixer by Azden

The Azden FMX-42 is a portable 4-channel audio mixer designed for professional and semi-professional field audio capturing. The FMX-42 features 4 balanced 3-pin XLR microphone inputs with individually switched +48VDC phantom power. A pair of balanced XLR outputs provide line or mic level (switchable) signal to cameras, recorders, etc.

Additional features include a switchable input limiter to reduce the possibility of overload distortion, Left / Center / Right Pan switches on all input channels and enhanced circuitry for improved signal-to-noise ratio. Overall, the Azden FMX-42 proves to be an affordable field mixing solution for event videos, ENG / EFP applications, documentaries, and more.

Balanced Mic Inputs  - The FMX-42 features 4 XLR microphone inputs. The balanced inputs deliver high gain and low noise floor. VU Meters Dual analog meters provide a comprehensive read on audio level.

Balanced Line or Mic Level Outputs Dual balanced line or mic level switchable outputs via XLR male connectors provide balanced audio signal to inputs on cameras and additional mixers.

2 Channel Addressable Outputs Incoming signal from either channel can be assigned to either left or right outputs if signal isolation is desired.

Input Limiters Both inputs feature high quality switchable limiters. The limiters protect against peak distortion due to overload.
