The AM1204FX RW compact mixers feature four mono microphone/line inputs in conjunction with two stereo line inputs for flexible input possibilities. Each channel features a super-musical 3-band equalizer, while mono channels also offer 75Hz low-cut filters for removing stage rumble and other unwanted low-frequency sounds. The AM1204FX RW features a 32-bit DFX processor with 16 preset effects - each with its own user-adjustable parameter! This new AM mixer is rounded off with a stereo USB audio interface that allows two tracks of audio to be streamed both to and from any modern PC or Mac computer. All mixers offer an addition ALT 3/4 mix that redirects muted signals from all channels to their very own mix. A universal power supply, accepting AC voltages from 100V to 240V, ensures the unit can be used globally.
