a. If the external DC power supply has its own shunt regulator, the DC power supply must be connected through the DC Output terminals on the amplifier. If either the internal shunt regulator on the amplifier or no shunt regulator at all are being used, the DC power should be supplied via the AC Input terminals on the amplifier. In this way, fuse protection is provided and polarity of the supply voltage is controlled within the amplifier.
