ENGLISH ■ Neutrik NL4FC Plug Wiring If you will be using the Neutrik connectors for speaker input, wire the plugs as shown to the right. Be sure to use proper speaker cable - NOT shielded instrument or line cable - for all speaker connections. 2- (NO USE) 1+ : HOT(+) 2+ (NO USE) 1- :COLD (-) Neutrik NL4FC connector ■ Speaker Cable Selection Speaker cables must carry a significant amount of current in order to drive a high-power speaker system. For this reason it is important to use heavy-gauge speaker cable for all speaker connections. Other types of cable can dramatically limit performance as well as being a fire hazard. Suspended Installation 1 The R112/R112C and R115/R115C can be used in suspended "flying" rigs by using optional long eye bolts (M10) and an appropriate suspension wire. For this type of installation replace the three bolts on the top and back of the speaker with the long eye bolts. 2 Refer to the diagram to the right for suspended installation details. Make sure that all wire and fittings used - including the ceiling structure - are strong enough to support the speakers. Bolts M10 long eye bolts
(Optional) Maximum 45 Degrees Suspension Cautions • Installation should be carried out by experienced personnel. • Some fittings may deteriorate due to wear or corrosion over extended periods of time. The installation should be checked thoroughly at regular intervals for safety. • Use only the specified M10 long eye bolts. • Always suspend the speakers using all three long eye bolts. • Never use the speakers' handles as suspension points. 6
