Neutrik Connectors 4-2
Never short or parallel the output channels of a CE-Series
amplifier to itself or any other amplifier.
Slide the connector insert (B) into the connector
housing (A), making sure that the large notch on the
outer edge of the insert lines up with the large groove
on the inside of the connector housing. The insert
should slide easily through the housing and out the
other side until it extends approximately
3
/
4
-inch (19-
mm) from the end of the housing (see Figure 4.5).

Chuck into Connector Housing
Slide the chuck (D) along the cable and insert into
the housing, making sure that the large notch on the
outer edge of the chuck lines up with the large
groove on the inside of the connector housing. The
chuck should slide easily into the insert/housing
combination until only approximately
3 /
8
-inch (9.5-mm)
of the chuck end extends from the back end of the
connector as shown in Figure 4.6.

Bushing onto Connector Housing Assembly
Slide the bushing along the cable and screw onto the
end of the connector combination as shown in Figure
4.7.
Note that the bushing features a special locking con-
struction which will prevent disassembly of the NL4FC
connector once this cap is tightened into place. Before
tightening, you may want to test the connector to make
sure it has been assembled properly.
Why Speakon?
For amplifiers, the most popular termination device on
professional products has been the dual banana (which
incidentally was pioneered by Crown with the DC-300
model). However, recent regulatory requirements in Eu-
rope have outlawed the use of the dual banana plug and
forced users to terminate speaker cables with spade
lugs or bare ends—an approach that is clearly not ad-
vantageous to the customer who wants to reconfigure
his system or quickly change out a defective product. It
is possible that similar regulatory controls will appear
worldwide over the next few years.
One solution to this problem is to use the Neutrik
Speakon
® connector. Here at Crown, we wanted to de-
velop a system for you that eliminated the need for spe-
cialized, time-consuming, interface cables. The major
loudspeaker manufacturers have been using Speakon
connectors for the input termination on their products for
several years now, so you can be assured of the
connector’s reliability in the workplace. With Speakon
connectors, you can plug straight from the amp to the
speaker, and start making those great sounds right
away.
The Speakon connector used on this amplifier meets all
known safety regulations. Once wired correctly, the con-
nector cannot be plugged in backwards, causing the
type of inverted polarity situations that are common with
banana hookups. It will provide a safe, secure and reli-
able method of interfacing your amplifier to the load.
