Azden FMX-42a 4 Channel Field Mixer

The Azden FMX-42a Field Mixer features 4 XLR inputs and switchable phantom power, 2 XLR outputs plus a mini-plug output, adjustable input level monitor level and VU meters and a 10-pin and mini plug camera return. It is the most feature-laden field mixer from Azden, it  includes a switchable input limiter that reduces the possibility of overload distortion, enhanced circuitry for reduced signal to noise ratio and Left-Center-Right Pan switches on all input channels. All four of the 3-pin XLR inputs have switchable +48V DC Phantom Power.
