QSC Audio SB-7218 사용자 설명서

The SB-5218/7218 has barrier strip screw ter-
minals for connection. The terminals accept up 
to #10 AWG stranded loudspeaker wiring. Use 
the largest wire size and shortest wire length 
possible for a given installation. Observe the 
polarity markings and keep polarity consistent 
throughout the system for best performance.

The terminals marker SPK2 may be used to con-
nect another SB-5218/7218 in parallel. Connect 
the wires as shown in the illustration, at right. 
Note: If the SB-5218/7218’s internal wiring has 
been modified in any way, this may not func-
tion. If this is the case, remove the terminal cup 
and verify the presence of the factory yellow 
jumper and blue jumper wires; remedy as 
required or have the loudspeaker serviced.

The transducers are wired in parallel inside the 
enclosure. If individual transducer connection is 
required, remove the terminal cup and remove 
the yellow and the blue jumper wires that are 
connected between the SPK1 and SPK2 termi-
nals. Replace the terminal cup and mark the 
enclosure with a note of the modification.
