Precautions

WARNING

•If you notice any abnormality, such as smoke, odor, or noise,

turn the power amp off immediately. Remove the power cord

from the AC outlet. Consult your dealer for repair. Using the

unit in this condition is a fire and electrical shock hazard.

CAUTION

• When choosing a location for your speakers, avoid the fol-

lowing:

- Direct sunlight, high temperatures (such as near heaters),

or excessively low temperatures.

- High humidity.

- Areas subject to excessive dust accumulation and vibra-

tion.

- Non-level or unstable surfaces.

• To prevent short circuits or breakage of cables, always dis-

connect cables prior to moving system equipment.

•When using two or more speaker systems, be sure match the

polarity (+/–) of the speaker system connectors to those at the

amplifier. If the polarities do not match, the sounds produced

by the speakers will interfere with each other, making it im-

possible to achieve a well-balanced sound field.

• This unit is heavy. Use two or more people to carry it.

•To avoid damage to your speakers and other parts of your sys-

tem, when you turn on your system, ALWAYS turn the pow-

er amp on last! This will avoid loud, damaging pops that will

annoy your audience, and blow your speakers. When you

power down, the amplifier should ALWAYS be turned off

first to avoid the same problems.

•Always turn the power switches of system components OFF

prior to connecting or disconnecting cables. Failure to do so

may result in damage to speakers as well as to connected

equipment.

• Do not output distorted sounds for long periods of time, as

this will cause the speaker to heat up, leading to a fire hazard.

In case an abnormality occurs during operation

Installation Operation

ENGLISH

This product, when used in combination

with amplification and/or additional

loudspeakers, may be capable of produc-

ing sound levels that could cause perma-

nent hearing loss.

DO NOT operate at high volume levels

or at a level that is uncomfortable. If you

experience any discomfort or ringing in

the ears, or suspect an hearing loss, you

should consult an audiologist.

To protect your speakers

When choosing a power amplifier to use with your

speakers, make sure that its power output matches the

speakers’ power capacity (refer to the Specifications on

page 7). Even if the amplifier’s power output is lower

than the speakers’ PGM (program) power capacity, the

speakers may be damaged when clipping of a high input

signal occurs.

The following may cause damage to speakers:

•Feedback caused when using a microphone.

•Continuous high sound pressure level produced by

electronic instruments.

•Continuous high-power output distorted signals.

•Popping noises caused by turning on equipment, or

by connecting or disconnecting system components

while the amplifier is turned on.

Poly Switch

All full-range loudspeakers are fitted with a self-reset-

ting poly switch that protects the high-frequency driver

from damage caused by excessive power.

If a loudspeaker cabinet loses high-frequency output,

immediately remove power from the unit and wait for

two to three minutes. The should allow the poly switch

to reset. Re-apply power and check the performance of

the high-frequency driver before continuing with the

power reduced to a level that does not cause the poly

switch to interrupt the signal.

On the R118W/R118WC sub woofer, the Poly Switch

protects the woofer and a similar routine should be fol-

lowed if its output is lost.

ENGLISH

Connection Examples

■Full-range Connection

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).

Impedance Considerations

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.

■Using a Channel Divider and Subwoofers

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.

■Phone Plug Wiring

Phone plugs for connection to the phone

jack inputs should be wired as shown to

the right. Be sure to use proper speaker

cable – NOT shielded instrument or line

cable – for all speaker connections.

■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

1The 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.

2Refer 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.
