6. Connecting
To connect the speakers simply push the Speakon plug into the socket and twist
the plug clock-wise to lock. Twist counter-clockwise and pull to disconnect.
Connection Polarity.
It is important to ensure that each speaker is connected with the same polarity.
Positive
speaker terminals should always be connected back to amplifier
positive
terminals, and
negative
speaker terminals connected back to amplifier
negative
terminals. Performance will be degraded if connections are made with incorrect
polarity.
Cable Choice.
Choice of cable type will be influenced by the application intended for your
Extreme Series speakers and the characteristics of other components in your
system. Your dealer or distributor will be able to advise. There are however some
simple guidelines to consider:
•
The external cable diameters compatible with Speakon plugs are as follows:
NL2FC (2-pole): 4mm - 10mm, NL4FC (4-pole) 5mm - 11mm (white Clamp
Ring), NL4FC (4 pole) 9.5mm - 15mm (black Clamp Ring).
•
Cable runs to each speaker should be kept as short as possible.
•
Short cable runs are especially important if the cable is of relatively small
cross-sectional-area.
•
If the cable is advertised as “directional” care should be taken to ensure that
its orientation is as recommended.
Extreme Series speakers are fitted with Neutrik
Speakon connection sockets. An appropriate Speakon
plug is included in each pack. Speakon sockets and
plugs provide a reliable, secure, and potentially
weather-proof connection.
Either 2-pole (Part No. NL2FC) or 4-pole (Part No.
NL4FC) plugs may be used. The supplied plug is a 2-
pole type. 4-pole Speakon plugs can additionally be
fitted with a weather-proof rubber sleeve (Part No.
BSL-WR).
Speakon plugs and accessories are widely available
from audio and electronic component distributors and
retailers.
Diagram Three
illustrates the assembly and connection
of a 2-pole Speakon plug. Remember to thread
the cable through the
Rear Housing
and
Clamp
Ring
before connecting it to the terminals. Strip
approximately 6mm of bare wire and connect to the
screw terminals within the Speakon. If using
-pole
Speakon plugs use the terminals labelled
+1
and
-1
.
Take care not to connect the negative and positive
terminals together and “short-circuit” the amplifier.
Make connections with the amplifier switched off. Once
the cable is connected to the terminals, the plug can be
reassembled. The
Clamp Ring
secures the cable as the
Rear Housing
is tightened.
