It includes two phantom-powered XLR microphone inputs and three stereo pairs of RCA jacks for input of CD players, AM/FM tuners, and other audio devices. Priority ducking for paging is offered on mic one and RCA source three.

    Rolls MA2152 reviews

    MA2152 5-Input Mixer/Amplifier is rated 4.0 out of 5 by 2.
    Rated 4 out of 5 by from Good Med size mix.amp This product is would be great in low ambiant enviorments with 70V. Remember that the Briged output is 70V not the both channels. That said it worked well but I did end up returing it due to bad shipping from the Rolls not B&H which bent the rack ears. Ducking worked great along with all the stereo inputs. we installed it in a pool which also had too much ambiant noise for the amp to push over without clipping.
