10.2 Input Connectors
The SLS and SBS loudspeakers have jacks that accept two types of connectors: Neutrik Speakons and
dual banana type plugs. Both are high current connectors and neither requires soldering to make the
connection from the wire to the connector. For permanent installations, either the banana plugs or
Neutrik Speakons make excellent connections that easily detach for service. For portable use or when
the loudspeaker is located where the wiring might be accidentally disturbed, always use the locking
Speakon connector. A Neutrik Speakon in-line connector is provided with the loudspeaker and is the
recommended connector. (Refer to the SECTION 10.5 “Connecting the Loudspeakers” for proper wiring
of the connectors).
10.3 Paralleling or Daisy-chaining Two Loudspeakers
The pair of Neutrik Speakon input jacks for the SLS models are internally wired in parallel. This means
that a second loudspeaker can be paralleled or “daisy-chained” from the first using a jumper cable. In
this way both loudspeakers will operate off the same amplifier channel. The jumper cable should be
wired at both ends for the appropriate operating mode according to SECTION 10.5 “Connecting the
Loudspeakers”. This capability functions for both the PASSIVE and BIAMPLIFIED modes. Note that
when using this function in BIAMPLIFIED mode, all 4 pins of the Speakon connector must be used for
the jumper.
The pairs of dual banana jacks for the SLS models are NOT wired in parallel with each other. However,
they are wired in parallel with the functionally corresponding +/– signal pins of the Neutrik Speakon
jacks. The banana jacks can also be used in lieu of the second Neutrik Speakon for paralleling another
loudspeaker off the first one. In this case a jumper cable with banana plugs wired identically at each
end can be used and plugged into a banana jack on each loudspeaker. Note that when using this
function in BIAMPLIFIED mode, two banana jumpers will be needed – one for the LF signal and one for
the HF signal.
10.4 Test Points
When using the Speakon connectors for the loudspeaker’s signal input, the banana jacks make
convenient test points for system set-up and servicing. Test instrument leads can be outfitted with a
banana plug connector making it easy to monitor and test the signal applied to the loudspeaker.
10.5 Connecting The Loudspeakers
The following diagrams show the wiring connections for the SLS and SBS loudspeakers. In all cases be
sure to observe proper polarity when making the connections. (Refer to CHAPTER 9 “Operating
Requirements” for amplifier and crossover requirements and CHAPTER 7 “System Configurations” for
controller/loudspeaker combinations.)
10.5.1 SLS PASSIVE Mode Operation (See FIGURE 4)
Operation of the SLS loudspeakers in PASSIVE mode requires putting the slide switch on the input
panel in the “Passive” (down) position. The input connections are made either to the right pair of
banana jacks or to either of the Neutrik Speakon connectors. Observe proper polarity when making
the connections.
