The MXR Series from American Audio was designed to give DJs the familiar tactile feel of a traditional DJ mixer while playing and controlling music digitally from computer software. Featuring three models ranging from 10" to 19"—10 MXR (2-channel), 14 MXR (4-channel), and 19 MXR (4-channel)—these MIDILOG™ mixers work with any MIDI Learn software or analog inputs like CD players and turntables. They feature a built-in DSP D-Core™ sound card with 4-in/4-out audio interface; balanced XLR outputs; 18 or 20 assignable MIDI control buttons; and MIDI navigation controls for easy access to a music library. Each unit includes 3-band EQ with rotary kills (treble, mid, and bass); crossfader curve adjustment; master, booth, and headphone level control; and mix controls. Models 14 MXR and 19 MXR offer a controller mode for routing USB output streams through master and headphone outputs. Featuring multi-voltage operation, the MXRs weigh 6-10 lbs.
