Xn: Two semi-paralleled 8-pin Neutrik Speakon
connectors are used for electrical connection on the
input panel. Note that one connector is specifically labeled for input connection and the other for output
connection. Pins 3 and 4 are paralleled between the two connectors; however, Pins 1 In are connected
to Pins 2 Out, while Pins 2 In are connected to Pins 1 Out. The HF driver is connected on Pins 4 In and
Out, the MB driver is connected on Pins 3 In and Out, and the LF driver is connected to Pins 1 In and
Pins 2 Out. This facilitates the amplifier wiring of multiple systems. When four Xn systems are jumped
from one to another via connection from output to input connectors, the amplifier home-run cable will
have four HF drivers on Pins 4 (for a 4-ohm load), four MB drivers on Pins 3 (for a 4-ohm load), two LF
drivers on Pins 2 (for a 4-ohm load) and two LF drivers on Pins 1 (for a 4-ohm load). When jumping
boxes from output to input connectors, the LF drivers alternate from Pins 1 to Pins 2 as successive
boxes are added to the chain. However, a wiring “trick” may be employed if it is desired to keep all of the
LF drivers on Pins 1 by plugging into the input of the first box, then jumping from the output of the first
box to the output of the second box – resulting in two HF drivers on Pins 4, two MB drivers on Pins 3 and
two LF drivers on Pins 1 with nothing on Pins 2. A similar wiring “trick” may be employed to keep all of
the LF drivers on Pins 2 by plugging into the output of the first box, then jumping from the input of the first
box to the input of the second box.
Xcn: Two paralleled 8-pin Neutrik Speakon
connectors are used for electrical connection on the input
panel. Because the connectors are paralleled, it does not matter which connector is used as the input or
output when paralleling Xcn systems. The HF driver is connected on Pins 4 and the MB driver is con-
nected on Pins 3. Although Pins 1 and 2 are not used internally in the Xcn system, they are paralleled on
the input panel. This allows an X-Array™ LF box (like the Xcb or Xb – which use Pins 1 and 2, but not 3
and 4) to be paralleled with an Xcn, allowing all eight conductors to be used in a single cable run to the
amplifiers. When four Xcn systems are jumped from one to another via the paralleled input-panel con-
nectors, the amplifier home-run cable will have four HF drivers on Pins 4 (for a 4-ohm load) and four MB
drivers on Pins 3 (for a 4-ohm load).
Xcb: Two semi-paralleled 8-pin Neutrik Speakon
connectors are used for electrical connection on the
input panel. Note that one connector is specifically labeled for input connection and the other for output
connection. Pins 3 and 4 are paralleled between the two connectors; however, Pins 1 In are connected
to Pins 2 Out, while Pins 2 In are connected to Pins 1 Out. The LF driver is connected to Pins 1 In and
Pins 2 Out. This facilitates the amplifier wiring of multiple systems. When four Xcb systems are jumped
from one to another via connection from output to input connectors, the amplifier home-run cable will
have two LF drivers on Pins 2 (for a 4-ohm load) and two LF drivers on Pins 1 (for a 4-ohm load). When
jumping boxes from output to input connectors, the LF drivers alternate from Pins 1 to Pins 2 as succes-
sive boxes are added to the chain. However, a wiring “trick” may be employed if it is desired to keep all of
the LF drivers on Pins 1 by plugging into the input of the first box, then jumping from the output of the first
box to the output of the second box – resulting in both LF drivers on Pins 1 with nothing on Pins 2. A
similar wiring “trick” may be employed to keep all of the LF drivers on Pins 2 by plugging into the output
of the first box, then jumping from the input of the first box to the input of the second box.
Xw12: There are two input panels on the enclosure (one on each end), with each having two paralleled
4-pin Neutrik Speakon
connectors for electrical connection. Because the connectors are paralleled, it
does not matter which connector is used as the input or output when paralleling Xw12 systems. The HF
driver is connected on Pins 2 and the LF driver is connected on Pins 1.
Xw15: The Xw15 is wired identical to the Xw12 with two input panels on the enclosure (one on each
end), with each having two paralleled 4-pin Neutrik Speakon
connectors for electrical connection. Be-
cause the connectors are paralleled, it does not matter which connector is used as the input or output
when paralleling Xw12 systems. The HF driver is connected on Pins 2 and the LF driver is connected on
Pins 1.
HELPFUL HINT: When wiring the X-Array loudspeaker systems, remember that all eight pins on the
input panels of all of the loudspeaker systems carry the amplifier outputs for the SUB, LF, MB and HF
simultaneously. This wiring scheme can be used to advantage minimize the number of speaker cables
that must be run to the amplifier racks. When wiring the Xw floor monitors, remember that there are two
