■ 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.
■ 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.
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.
