X12 • X14 • X24 OWNER'S MANUAL
Congratulations on your purchase of a Renkus-Heinz loudspeaker controller. It has been designed to
provide years of trouble-free, high performance operation. We hope you enjoy it.
The X12, X14 and X24 are a series of loudspeaker controllers designed to be used specifically with
speakers produced by Renkus-Heinz. These loudspeaker controllers provide electronic crossovers,
equalization, delay, and loudspeaker protection circuitry tailored specifically to a particular model
loudspeaker. By using one of these controllers, you are assured of obtaining the optimum in loudspeaker
performance and protection.
Caution: The X12, X14 and the X24 are configured for a particular Renkus-Heinz loudspeaker
model. Do not use with any other loudspeaker model other than the internally programmed intended
loudspeaker model. Use of the wrong loudspeaker model may result in loudspeaker damage.
Introduction
Your Renkus-Heinz contr oller was completely tested and inspected before leaving our factory and should
have arrived in perfect condition. Please carefully inspect your controller and its shipping carton for any
noticeable damage, and if any damage is found, immediately notify the shipping company.
Only the consignee may institute a claim with the carrier for any damage incurred during shipping. Be
sure to save the carton and all packing materials for the carrier's inspection.
It is also a good idea to save the carton and packing material even though the controller arrived in good
condition. If shipping the controller should ever be required, it should be shipped only in its original
factory packing.
Important:
Your Renkus-Heinz controller contains no user-serviceable parts and all
service should be referred to qualified service personnel. We recommend
that it be returned to the factory in its original packing carton if factory
service is required.

Each controller is specifically “programmed” for a particular Renkus-Heinz loudspeaker. The model
number(s) for the loudspeaker(s) your controller is programmed for are shown on the rear panel.
This “programming” is accomplished using plug-in Crossover, EQ/Delay and Limit modules. This allows
the controller to be re-programmed for different loudspeakers by changing modules.
All three controller models use the same circuitry and same plug-in modules. The only difference between
the three models is the number of input and output channels.
Model X12 (1 channel 2-way)
The X12 is a single channel 2-way (1 in 2 out) controller designed for use with active 2-way loudspeakers (or
3-way loudspeakers set up for bi-amp operation) in single channel (mono) systems. It is also often used as a
"sub controller" and as a controller for passive 2-way loudspeakers. Typical system wiring diagrams for the
X12 can be found on the next page.
Model X14 (1 channel 3-way plus sub)
The X14 is a single channel 4-way (1 in 4 out) controller designed for use with active 3-way loudspeakers
(plus the possible addition of a subwoofer) in single channel (mono) systems. It is also used with active 2way loudspeakers in single channel systems having subwoofers. Refer to page 7 for system wiring details.
Model X24 (2 channel 2-way)
The X24 is a dual channel 2-way (2 in 4 out) controller designed for use with two-way loudspeakers in dual
channel (stereo) systems. It is also used in stereo systems having 3-way loudspeakers that are set up for biamp operation. Typical system wiring diagrams are shown on page 8.

of the subwoofer and any associated loud speaker will overlap. This overlap can be
eliminated by using the X12's FR/HF output
to drive the associated loudspeaker's
amplifier or controller. The FR/HF output
is band limited to match the subwoofer's
crossover point. When the FR/HF output is
used in this fashion, the HF + & - pins
on the X12's SenseLine connector must be
shorted together!
Note 2.
Any unused Sense Line terminals
should be shorted together to prevent
their associated red LED warning lights
from being "on" constantly.
Note 3.
If the X12 was being used as a controller
for a passive loudspeaker instead of for a
Subwoofer
subwoofer, the Power Amplifier would be
connected to the FR/HF output connector,
instead of to the Sub/LF connector.

Plug-In Modules
To insure the highest possible loudspeaker performance while still providing optimum protection for the
loudspeaker, each Renkus-Heinz controller is specifically configured for a particular Renkus-Heinz
loudspeaker model.
This configuration is accomplished by three “plug-in” PC boards or modules used inside the controller.
These modules are the Crossover, EQ/Delay, and Limit boards. The combination of these three boards is
unique for each loudspeaker model.
Figure 4 shows the plug-in boards and their location on the main "mother" boards inside the controller.
Crossover Board:
The crossover board contains the active filters required for creating the crossover points. The filters are
either 3rd or 4th order (18dB/octive or 24dB/octive) electronic filters. The corner frequency and filter
order is selected to optimize the performance of the associated loudspeaker model.
EQ/Delay Board:
The EQ/Delay board provides up to 3 bands of parametric equalization per channel. This equalization is
used to smooth and extend the frequency response of its associated Renkus-Heinz loudspeaker.
When a particular loudspeaker model requires time offset alignment, the delay section of this board is
utilized. It provides the desired signal delay.
Limit Board:
The limit board sets the maximum safe allowable excursion, thermal, and peak audio levels for its
associated loudspeaker.

AC Receptacle / Fuse Holder:
This receptacle accepts an IEC 320/CEE-22 AC power connector. A line cord with the appropriate matching
connector is supplied with the controller.
Before plugging in the AC power cord, make sure the AC voltage selector switch is set to the correct position.
An incorrect setting of the AC voltage select switch may result in unit failure.
The fuse holder is integrated into the AC power cord receptacle. The fuse can only be accessed by first
unplugging the AC power cord from the AC receptacle. When the fuse drawer is opened, the innermost fuse
is the active fuse, the outer fuse is a spare fuse. The controllers use a 5 x 20mm 0.400A slow blow fuse.
Caution: Replace fuse only with same type fuse.
AC Voltage Selector Switch:
This switch allows the controller to be configured for the appropriate AC line voltage. The unit can either be
set for 115VAC or 230VAC. Use the 115VAC position for AC line voltages ranging from 100 to 120VAC.
Use the 230VAC position for voltages ranging from 220 to 240VAC.

Set-Up
Mounting
Mounting:
For most applications, mount the controller in the amplifier rack. This will allow short sense cables from the
amplifier to the controller. This also reduces the possibility of ground loops between the controller and the
amplifier.
Allow at least one rack space between the top of the amplifier and the bottom of the controller. This will
allow space for the heat to escape from the amplifier and also reduce the coupling of AC hum from the
amplifier into the controller. Always support the rear of the controller chassis in the rack especially if used in
a portable application.
Balanced and Unbalanced Cabling:
The inputs and outputs for the controllers are electronically balanced and use standard XLR type connectors.
You can use either pin 2 or pin 3 hot on the input provided you follow the same convention on the output
audio connectors. Pin 1 is chassis ground and its use is optional. Whether to connect pin 1 or not will
depend upon your application. Use the method which minimizes system hum.
If it is necessary to connect the controller to a single ended system, connect pin 1 to ground and use either pin
2 or pin 3 for the audio signal (see drawings below). Single-ended connection results in a gain reduction of
6dB.

Audio Inputs:
Connect the input audio from the audio output on the mixing board. This can either be a balanced or an
unbalanced signal. Refer to previous section regarding balanced and unbalanced connections.
Audio Outputs:
Connect the audio outputs to their respective audio amplifier input. This can either be balanced or an
unbalanced signal. Refer to previous section regarding balanced and unbalanced connections.
Amplifier Selection:
The selection of the wattage of the amplifier is not critical. If the amplifier has higher wattage than required,
the controller will limit the amplifier output to a safe speaker operating level. When using more than one
amplifier on the same controller output, all amplifiers require the same gain. While some range of sensitivity
can be accommodated by the controller, an amplifier voltage gain of 40 is preferred. For best results, always
run every amplifier at full gain.
Sense Connector:
For connecting the sense lines a mating 4 pin solderless type mating connector has been supplied with the
controller. This connector will accept 14 to 22 AWG size wire. To connect a wire to the connector, insert a
small screwdriver in one of the screwdriver slots, press and hold down the spring clip while inserting a
stripped wire into the corresponding wire opening. See Figure 9 below for details.

Caution: Do not connect more than one amplifier output to one sense input. Damage to the amplifier may result.
Note: If the sense line is not connected, that audio channel output will be muted and all the red LED's associated with
that channel will light.

Important:
Your Renkus-Heinz controller contains no user-serviceable parts and all
service should be referred to qualified service personnel. We recommend
that it be returned to the factory in its original packing carton if factory
service is required.
No sense lines connected.
Amplifier volume control turned down to far, resulting in inadequte gain
Excessive signal input level to the controller.
Sense lines inproperly connected, crossed between low and high outputs.
Check fuse.
Check signal source and verify input wiring.
Reduce system level and/or avoid extreme equalization.
Add more amplifiers/loudspeakers to the system.
