■ 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.
