MA4120

Multiplex Professional Public Address Amplifier

Overview

The MA-4120 is a simple and inexpensive high quality mixing amplifier for zoning applications in small and medium size commercial installations. It combines 4 x 120 W independent amplifier modules with a five channels input mixer. It is a versatile and easy operating paging system for bars, restaurants, retail outlets, offices, and all other venues where up to four different areas need to be controlled individually.

The MA-4120 is very easy to use. No computer, no software, no sophisticated technology, just an analog device with simple and intuitive settings. Every single source from channel 1 to 5 can be routed to one of the four outputs just by pressing a switch. The control of the signal input is limited to high and low EQ plus gain and volume. In case of long distances between de device and the line speakers, it is possible to monitor the signal send to each output through a dedicated speaker terminal on the rear panel. All zone outputs are available on terminal block connectors for easy interfacing with other installed equipment.
