The MA-725F is a 6-input matrix mixer: 4 of its inputs are configured for BGM or other line-level sources, while two balanced inputs are designated for priority sources, such as paging mics or message players. This is coupled in a single chassis with a 4 x 250W (@70 or 100V) Class D amplifier section, capable of driving large speaker compliments with maximum efficiency.
