5 inputs and 4 outputs
5 Mic/Line inputs
MIC 1 Priority
18 V DC operation

MPA-4150 and MPA-4250 are P.A. amplifiers specifically designed for commercial applications. It is an ideal solution for bars, restaurants, retail outlets, offices, schools and other applications where paging and background music are required. The MPA-4150 combines a 4 x 150 W amplifier with a four inputs mixer; it is a versatile and easy operating paging system. Mono inputs are available on combo balanced XLR / TRS 6.35 mm jacks. A switch on each input selects a line or microphone level with a 18 V phantom power option. MIC 1 input features an automatic priority function. Both devices offer a built-in MP3 player for BGM or recorded messages. The main output section accepts 25, 70 and 100 V constant voltage line or 4 Ω impedance loads. Two switchable zone outputs are available with their own volume control.
