The ART MX624 is a versatile, six-channel, two-zone output stereo mixer. It features six stereo RCA inputs with 3 XLR microphone inputs. Each mic input includes phantom power with pad selection. You have the option to plug in a music player or connect multiple music players via the daisy chain method (connect multiple units to one another without the need to connect each unit to a power source) through the two stereo inputs. Each channel provides Zone 1 and Zone 2 selection buttons. There is also a level control and a bass and treble tone control for each output.
