Azden FMX-42a 4-Channel Microphone Field Mixer

Key Features

  • 4 XLR Inputs
  • Phantom Power
  • Input Limiter
  • 2 Balanced Mic/Line XLR Outputs

The Azden FMX-42a is a portable 4-channel audio mixer designed for professional and semi-professional field audio capturing. Equipped with both mini-jack and 10-pin camera returns, the FMX-42a also features 4 balanced 3-pin XLR microphone inputs with individually switched +48V 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. The FMX-42a can be powered either by 6 AA batteries or an optional 12 VDC external power supply. A ballistic nylon carrying case is included.

The FMX-42a is an affordable field mixing solution for event videos, ENG/EFP applications, documentaries, and more.

Features:

  • On-board A/D converter and 2-channel mini-USB digital audio output
  • Mini-USB output connects to computer, smartphone, or tablet
  • Simultaneous use of both outputs allows the analog signal to be sent to the camera while a backup digital signal can be sent to a smartphone or tablet or computer via mini-USB
  • 4 balanced XLR line/mic inputs and pan controls
  • Switchable 48V phantom power and limiting
  • Professional-quality VU meters
  • 2 balanced XLR outputs (line/mic switchable)
  • Stereo mini-jack output for DV cameras
  • 6 x AA battery powered
  • Optional A/C adapter (sold separately)
