Features

Highly visible Organic LED display with high resolution metering offering both VU and peak level, with the option of stereo or mono.

The display will also show various mixer setting parameters, such as mic/line and phantom power on/off selections.

3 channel input (line or mic) and 2 channel main outputs are equipped with high quality signal transformers to resist external noise.

Sub output, tape output, and AUX output (you can choose which channel to assign).

Dedicated monitor return input to check the audio from VTR or camera feeds.

AUX input can also be merged to the stereo bus in addition to the monitoring feature (cascade connection is possible).

Main and sub outputs offer switchable level settings at +4/0/ -20/ -60.

The output has an analog limiter using VCA (the threshold and ratio parameters are adjustable).

Two headphone outputs are available with standard and mini jacks (you can choose a desired channel and PFL with the monitor selector knob).

Light but robust aluminum body construction. The large solid aluminum fader knobs are exclusively machined for the FM-3.

High quality faders offer superb reliability in severe work conditions. The faders use high-quality conductive plastic and a strong metal shaft construction.

Pop up knobs are used for trim, high pass filter, and the master to avoid unwanted changes.

The FM-3 runs on 8 AA batteries(it will also run on DC12-24V external power).

Alkaline batteries will run for approximately 6 hours, the remaining battery capacity will be displayed on both the Organic LED display and an LED indicator.

DC output is available via a HIROSE HR10A-4P connector, which is very useful for powering external devices such as a wireless receiver.
