Peavey ICS 4200 - Manual (Page 14)

Use of a 70 Volt matching transformer is possible with a 140 Volt system by connecting the tap that is
rated for 1/4 power or less of desired 70 Volt tap. For example‚ a ceiling loudspeaker with a 70 Volt
input tapped for 20 Watts is to be used with a 140 Volt constant-voltage system. The 140 Volt system
will need to be connected to the 5 Watt tap in order for the loudspeaker to produce 20 Watts. If a 5
Watt tap is not available‚ use the next lower tap.
