MURATA MA3

The MA 3 is a three-channel amplifier designed to operate reliably in commercial environments. The MA 3 was specifically designed for use in paging, foreground Music and Background Music Distribution. The MA 3 uses a conventional linear power supply with a toroidal transformer. This configuration minimizes the emissions associated with switching supplies and noisier transformer designs. The power supply features independent secondary supplies for each channel, minimizing load regulation interaction and crosstalk.
