Description

FM-4 4 Channel Portable Mixer

As a 4-channel portable audio mixer designed specifically for EFP, broadcast, on-location TV and film applications, you would expect exceptional audio performance with flexible output options and the FM-4 does not disappoint. Each of the 4 balanced XLR inputs can accept mic or line level inputs and features 12T and 48V Phantom power, an ultra-low noise pre-amp design with high quality custom transformers and switchable Hi Shelving EQ and Mid Sweep EQ. Metering is taken care of by an easy to read, highly visible organic LED display with high resolution metering offering both VU and peak level indication, battery level and selectable stereo and mono modes.

There are multiple output options including sub outputs, a Tape output and 2 x AUX outputs with channel select. The main outputs (x2) and sub outputs (x2) also double as 1-4ch Direct Out (post-fader). In addition, a dedicated monitor return input is available for referencing audio from VTR or Camera feeds.
