WL218-sw Controls and Connections
Input Connections
The WL218-sw input connectors are a pair of Neutrik 
NL4's wired in parallel. See Table 2 or the WL218-sw 
Input Plate for connector pinout.
Note pin numbers 2+ and 2- are wired 
straight through from one connector to the 
other. This accommodates using one input 
cable assembly (where appropriate) for sub-
woofer and full range loudspeaker connec-
tions. Additionally, pin numbers 1+ and 1- of 
both NL4s are wired in parallel.
The WL218-sw loudspeaker is not equipped 
with a crossover network. All signal pro-
cessing must be done before connecting 
audio power to the loudspeaker.
Reconfiguring the Input Connections for 
Separate Transducer Connection
If separate transducer connection is required, the input 
plate may be removed and the wiring altered so that 
each transducer has a separate, dedicated connection. 
Or, the transducers can be connected in parallel on pins 
1+, 1- or pins 2+, 2-.
If alterations to the wiring are made, ensure 
the input panel and connectors are clearly 
marked so the next user is aware of the mod-
ification made.
