■ 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.

- We do not recommend connecting more than two 8 ohm speakers in parallel two parallel connected 8 ohm speakers have a total impedance of 4 ohms which is the minimum that should be connected to one amplifier output channel the r112 r112c r115 r115c r12m r12mc r15m r15mc and r118w r118wc are 8 ohm speakers and two of these can safely be paralleled on one output the r215 r215c however has an impedance of 4 ohms and should not be parallel connected with another r215 r215c or any other model p.4

- Each speaker features three input parallel connectors two 1 4 phone jacks and one neutrik nl4mp connector use either a phone jack or the neutrik connector to receive input from your sound system power amplifier one of the spare connectors can be used to parallel connect an additional speaker keeping in mind the impedance considerations mentioned below p.4
- Connection examples p.4
- Using a channel divider in a multi way system like the one shown in the diagram can provide superior dynamic range and overall sound quality the channel divider divides the line level audio from the preamplifier or mixing console into separate frequency bands that are then sent to separate power amplifiers the power amplifiers drive speaker systems selected for optimum performance in the corresponding frequency ranges p.5
