More than one speaker can be connected to each channel provided the total impedance per channel is not less than 2 ohms. In bridged mode the minimum total impedanceshould not be less than 4 ohms.100V line operationA single channel of an XiB can deliver 1250W in to 2 Ohms, therefore the RMS voltage at the speaker terminals when delivering this will be V(1,250 x2) = 50V.If each channel is not loaded to full capacity of 1,250W (typically a 70V / 100V application will not load it this heavily) then the voltage will be higher than this because the powerrails will not be sagging so much; approximately 60V.Dependent on which voltage you use, a single channel will drive a 70V line to within either 3dB or 1.3dB of maximum and it will drive a 100V line to within 6dB or 4.5dB ofmaximum.A bridged pair of channel can deliver 2,500W in to 4 Ohms which equates to an RMS voltage of 100V or approximately 120V with a lower load than the full 2,500W.
