The AM1204FX 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. All AM1204FX 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 voltage from 100V to 240V, ensures the unit can be used globally.
