The MA 4120 MKII is a robust 3U rack‑mount mixer amplifier delivering 480 W (4 × 120 W RMS) across four independently controlled zones. With five input channels—including four combo XLR/jack with selectable mic/line/phantom power and one stereo RCA—this unit offers full audio routing flexibility. Every input channel supports individual gain, bass/treble EQ, mute, and zone assignment, while zone outputs include volume control, LED VU meters, monitor output, and support for low‑impedance and 100 V constant‑voltage speaker systems. Its analog simplicity—without reliance on software or digital setup—makes it a reliable choice for installers and system integrators.

  • Commercial & Public Venues: Recommended for multi-zone background music and paging in restaurants, cafés, pubs, retail stores, gyms, factories, offices, churches, and schools
  • Educational & Religious Facilities: Popular in schools and places of worship, where announcements, background music, and zone-specific content (classrooms, halls, corridors) require centralized control
  • Hospitality & Leisure: Well-suited to bars, beer gardens, entertainment venues, sports canteens, and outdoor spaces—supporting different zones with unique audio and paging capabilities
  • Office & Industrial Installations: Ideal for commercial buildings, warehouses, fitness studios, where zone control, paging, and robust, unattended operation are needed
