the proper wiring is shown on the model number plate. Always use crimp-on terminals with the terminal strip connections - do not connect
bare wire.
It's possible that your speaker was specially ordered with a different type of connector, so always be sure to check the model number plate
on your loudspeaker and follow the wiring diagram and instructions it displays.

Standard connections shown. Check model plate for your specific connection!

OPERATING TIPS
• Don’t drive any of your electronic equipment into clipping, particularly the power amplifiers. This can damage your loudspeaker.
• If driven into clipping, even the amplifier with a power output rating lower than Renkus-Heinz’s power rating can cause damage to a loud-
speaker.
• Avoid sustained microphone feedback. This may cause failure of mid and high frequency drivers.
• Avoid extreme boosts on equalizers as these can cause excessive input to the drivers at the boosted frequencies. Cutting frequencies is
preferred to correct for frequency response problems. These problems include attenuating feedback frequencies or reducing excessive en-
ergy at certain frequencies due to room acoustics.
• Your loudspeaker should sound very good. However, even the finest loudspeaker won’t sound good in a room with poor acoustics. There is
little you can do to overcome room acoustic problems with electronic adjustments. Carefully placing and aiming of the loudspeaker so that
most of the sound is directed only at the audience is helpful in difficult rooms.
• Renkus-Heinz loudspeakers are capable of sound levels that can damage human hearing. Take precautions so that audiences are not ex-
posed to such levels. If you must expose yourself to these kinds of volume levels, wear hearing protection.
• Be careful when moving or lifting the loudspeaker. Careless handling could result in injury to you or damage to the loudspeaker.
SWITCHING TO BI-AMPLIFIED OPERATION
Some Renkus-Heinz loudspeaker models can be switched from fully passive operation using the inter-
nal crossover to bi-amplified operation using an external controller/crossover/DSP unit. These models
can be identified by a round indicator window below the model name on the input connector panel. If
you choose to use your loudspeaker in the bi-amplified mode, be sure to use a Renkus-Heinz controller
or obtain the DSP settings for your model from Renkus-Heinz. Be sure to follow the section on setting
limiters in this manual if you choose to use your own DSP unit. Your loudspeaker will have shipped
wired for fully passive use, to convert to bi-amplified usage, follow these steps.
1) Remove the screws holding the input panel to the loudspeaker cabinet and then carefully remove the
panel from the cabinet. A loudspeaker cable plugged into one of the inputs makes a handy “handle” for
this procedure. See figure one.

No Sound. Check to be sure the amplifier is on.
Check all cables for clean tight connection
to the correct terminals.
Check any head-end equipment, is there a
mute engaged in a DSP for example.
Unplug the speaker cable at the loud-
speaker and plug it into a known good
speaker. If still no sound, problem is up-
stream in the electronics. If the known good
speaker works, see the section on evaluat-
ing failed loudspeakers.
Check to be sure the amplifier is on.
Check all cables for clean tight connection
to the correct terminals.
Check any head-end equipment, is there a
mute engaged in a DSP for example.
Unplug the signal cable at the loudspeaker
and plug it into a known good amplifier &
speaker. If still no sound, problem is up-
stream in the electronics. If the known good
speaker works, see the section on evaluat-
ing failed loudspeakers.
Distorted Sound. Make sure no electronics are being over-
driven or are clipping--check your gain
structure.
Unplug the speaker cable at the loud-
speaker and plug it into a known good
speaker. If the sound is still distorted, prob-
lem is upstream in the electronics. If the
known good speaker is undistorted, see the
section on evaluating failed loudspeakers.
Make sure no electronics are being over-
driven or are clipping--check your gain
structure.
Unplug the signal cable at the loudspeaker
and plug it into a know good amplifier &
speaker. If the sound is still distorted, prob-
lem is upstream in the electronics. If the
known good speaker is undistorted, see the
section on evaluating failed loudspeakers.
No highs or no lows. Check any upstream DSP for high-pass or
low-pass filters or EQ. On bi-amplified sys-
tems, check all connections, be sure nothing
is muted. Check any upstream DSP for high-pass or
low-pass filters or EQ. Check to be sure
none of the channels are muted on the am-
plifier.
High frequencies cut off and then come
back after a few minutes, then cut off
again. Most Renkus-Heinz loudspeakers are
equipped with self-resetting circuit breakers
for high frequency driver protection. If it is
tripping, it is a sign that you are overpower-
ing the HF driver. This is most commonly
caused by using excessive high frequency
equalization boost. Reduce or eliminate any
HF boost you are sending to the loud-
speaker and/or reduce the overall drive
level. Some of Renkus-Heinz' self-powered loud-
speakers are equipped with self-resetting
circuit breakers for high frequency driver
protection. If it is tripping, it is a sign that you
are overpowering the HF driver. This is most
commonly caused by using excessive high
frequency equalization boost. Reduce or
eliminate any HF boost you are sending to
the loudspeaker and/or reduce the overall
drive level.
Bi-amplified loudspeaker lacking both
low and high frequencies. Response
seems limited to 200 Hz to 5-7 kHz. The outputs of the controller/crossover/DSP
are reversed; the high frequencies are going
to the woofer and the low frequencies are
going to the Mid-High or High frequency
driver. N/A
Bi-amplified loudspeaker has a large dip
in it’s response at the crossover fre-
quency. Check polarity of each section and check to
be sure that the correct woofer delay is en-
tered in any third-party DSP crossovers. N/A
RPA Cluster has large peaks and dips in
the frequency response in areas between
adjacent loudspeakers. Check polarity on all cluster elements. If you
are not using a Renkus-Heinz controller, be
sure to carefully use the recommended DSP
settings. Make sure that all amplifier chan-
nels have the same voltage gain. Be certain
that loudspeakers are assembled in the cor-
rect order. Check polarity on all cluster elements. Make
sure that all volume controls are set the
same. Be certain that loudspeakers are as-
sembled in the correct order.
