Absolute maximum loading for MZ-280Q per zone is shown in the table below. Best practice states a roughly 10% de-rating margin
should be applied to these figures to allow for cable loses etc.

CALCULATING MAXIMUM LOADING
For Lo-Z modes (4 or 8 ohm) you should never load the amplifier below its rated minimum load impedance per zone. For example,
in 4 ohm mode you may connect either one 4 ohm loudspeaker, or two 8 ohm loudspeakers connected in parallel
For Hi-Z modes (70V or 100V) you should never load the amplifier greater than its rated maximum power per zone. For example, MZ-
280Q is 240W in 100V mode so you may connect eleven TNi-C8 loudspeakers running in 100V/20W mode (20W * 11 = 220W)
Depending on the scenario, a 10% derating may be required
11 TNi-C8s running at 20W = 220W
A safe margin of 20W is allowed for cable losses
