PCX Series Wiring and Connections
All PCX Series loudspeakers feature the same style
input connections. Input connections are made via a 4
Conductor (2 pair) Barrier strip, the pairs are internally
paralleled. Polarity of the barrier strip is indicated in
the pocket.
When connecting a PCX Series loudspeaker to an am-
plifier, please connect the positive (+) conductor from
the amplifier to the positive (+) barrier strip, and the
negative (-) conductor from the amplifier to the nega-
tive (-) barrier strip. Many speakers can be connected
together on one amplifier channel in parallel or series/
parallel using the second internally paralleled barrier
strip.
Pay careful attention to cable type when selecting
cabling for your PCX Series loudspeakers. Cabling with
too small a cross sectional area relative to impedance
load and cable length can result in greater power loss
and reductions in sound quality. Under the majority of
conditions, 12 AWG cabling will be appropriate, how-
ever when cable runs are very long wire gauge should
be increased.
When selecting an amplifier to drive PCX Series
loudspeakers, care should be taken to ensure you
have appropriate output capability. Please select an
amplifier with the appropriate amount of power for the
application, typically we recommend at least 3 dB of
amplifier headroom. Ensuring that more than enough
power is available will prevent driving the system into
overdrive reducing possible damage to both the ampli-
fier, and loudspeaker.
When running multiple PCX Series loudspeakers in
parallel while in Low Impedance mode, pay careful at-
tention to amplifier stability under heavy load. Imped-
ance varies by frequency and while nominal imped-
ance is a good indicator of a loudspeakers load some
frequencies will have lower impedance than what is
nominal.
