X12 • X14 • X24 OWNER'S MANUAL
Introduction
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.
Your Renkus-Heinz controller 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.

X12 • X14 • X24 OWNER'S MANUAL
The X12, X1 and the X24 are designed to be all encompassing units. They include crossovers, equalization, time alignment delay, and protective circuitry for specific loudspeakers in a single compact unit. This simplifies system design, reduces racks space requirements and lowers overall system costs.
A block diagram of the X12 controller is shown below in Figure 1. The X14 and X24 controllers are the same, except for the number of channels and/or the number of outputs.

Limit Module
Figure 1: X12 Block Diagram
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 2- way 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.
