"CONSTANT POWER SWITCH Set the rear panel slide switch to match the
impedance of the speakers used. Use the combined impedance value if you
are connecting speakers in series or parallel. Choose the nearest match
if the value is not exactly 4 or 8 ohms. Note that no damage will be done
if the switch is left in the wrong position. However, you may not benefit
from the full capability of the amplifier.
􏰀 Constant power explained The typical amplifier is optimised to
produce full power into 4 ohms and therefore considerably less into 8
ohms. The PA Series features a unique facility that ensures you get full
power output into either 4 or 8 ohm speakers. It does this by
reconfiguring the power supply for optimum current (4 ohms), or voltage
(8 ohms)."

.Perhaps this is why. They also have the ability through switches to
delegate signal to the .individual amps for mains and monitors.


Huh? I would suggest Mr. Carver was doing what he was best known for;
taking an unneeded or ordinary function, obfuscating or renaming it, and
making it a "feature".
