CE Series Service Manual
Rev.D
Neutrik Connectors 4-1
4 Neutrik Connectors
The CE-Series of amplifiers uses Neutrik Speakon
connectors for the outputs. While the Reference
Manual contains detailed instructions on how to as-
semble these connectors, we thought we would in-
clude the information here as well. This may help in
troubleshooting problems that may have arisen from
incorrect assembly.

Order of Assembly for the Neutrik Speakon NL4FC Connector
You will need two (2) Neutrik Speakon
®
NL4FC con-
nectors to interface with this amplifier.* You will also
need high-quality two- or four-conductor speaker
cable with the appropriate end-connectors to fit the
inputs on your speakers, a pair of needle-nosed pliers
and a 1.5-mm hex key to assemble the Speakon con-
nectors.
To assemble the Neutrik Speakon NL4FC connector,
complete the following steps:
Slide the bushing (E) and chuck (D) onto the end of
the cable as shown (Figure 4.1).**
Strip approximately 3 /
4
-inch (19-mm) of casing from
the cable end. Strip approximately
1
/
4
-inch (6-mm)
from the end of each of the conductors down to bare
wire.
Slide the end sleeves (C) onto the wire ends and
crimp in place.

** Your NL4FC connector kit should contain both a black and a white
chuck. Use the white chuck for cable with a diameter of 0.25- to 0.5-
inch (6.35- to 12.7 mm). Use the black chuck for cable with a diameter
of 0.375- to 0.625-inch (9.525- to 15.875-mm).
Insert each wire with end sleeve into the top of appro-
priate slot of the connector insert (B) as shown in Fig-
ure4.2. Use a 1.5-mm hex key inserted into each side
slot to tighten the connection.
If the Mode switch is in the “Stereo” position (for ste-
reo configuration), connect the positive (+) and
negative (–) leads of each wire to the appropriate
Channel 1 and Channel 2 connectors as shown in
Figure 4.3. You may use all 4 poles of the Channel 1
output connector to feed both speakers, if you wish.

If the Mode switch is in the “Bridge” position (for
mono configuration), connect the load across the (+)
terminals of the connector as shown in Figure 4.4.
For Bridge-Mono Mode, non-inverting output, Ch1+
is the positive (+) and Ch2+ is the negative (–).
