PCX Series Mode Selection Switch
PCX Series loudspeakers can be installed in many
different ways, and our Mode Selection Switch helps
facilitate easy selection of the desired operating condi-
tions.
All models feature a traditional Low Impedance mode,
and a 70/100 V mode which is ideal for distributed
audio systems with high numbers of loudspeakers.
When operating in Low Impedance Mode, sound qual-
ity can be impacted by the power loss associated with
long cable runs, and the increase in amplifier load with
increasing numbers of loudspeakers.
When dealing with very long cable runs, or large
numbers of loudspeakers, Renkus-Heinz recommends
using your PCX Series loudspeaker in 70/100 V mode.
When operating in 70/100 V mode, many loudspeak-
ers can be installed in parallel on each amplifier chan-
nel which can greatly simplify installation of larger
systems. Various wattage taps in each voltage range
helps to give additional flexibility when deploying large
numbers of loudspeakers.
When operating the Mode Selection Switch please
note that the switch does not rotate 360 degrees and
there are only 6 positions. Position number 1 is Lo-Z,
rotate clock-wise to reach the 5 additional switch po-
sitions. Position number 6 is the highest wattage tap,
either 60 W (PCX4), or 100 W (PCX8 and PCX16), ro-
tate counter-clockwise to return to the other positions.
Do not attempt to rotate past position 1 or position 6
or damage will occur.
