The amplifier or power amplifier is the device responsible for amplifying the signal that the mixer delivers so that it can sound through our speakers. Amplifiers for distributed, hight impedance or 100 V lines are a "special" type of amplifiers for high impedance speakers, as they are usually the loudspeaker ceiling speakers. We always have to choose the right amplifier for the speakers that we are going to connect it to.
In this case, they have only one output channel.
