CXA-12

Constant curvature line source

High Output, self powered (class D switch mode power supply with PFC), constant curvature line array element.

Description

The CXA-12 enclosure is a constant curvature line array element designed for multiple configurations, with a maximum of 4 enclosures.

The CXA-12 uses one 12″ LF/MF speaker next to a custom Multidriver waveguide system. The enclosure is self-powered with a total of 1400W (Class D, witch mode power supply), with PFC system and DSP processor with linear phase FIR filters.

It is ideal for a wide variety of applications, its design allows you to configure installations with symmetrical dispersion or fly the boxes vertically. The enclosure has a complete range of accessories that facilitate its use both in touring as in fixed installations.

For low frequency support the CXA-18S subwoofer is also available, either to be flown or stacked with the CXA-12 without the need for any rigging accesories.

DSP configuration

DSP module configuration panel

On the back pannel of the cabinet you will find the digital control area. From the compact joystick located below the screen you are able to configure the basic adjustment functions of the internal DSP.

Just move the joystick to select the icons on the left of the screen. You can enter into the following functions: Home, settings, folder, configuration and information. Please note that you must apply the desired configuration in each one cabinet and requires electrical power to work.

If changes are not made the display will automatically dim to avoid unnecessary light in situations where light is not wanted. To re-activate the light simply press the joystick.

The following screens are an example and may vary slightly for each cabinet.

Configuration panel:

	HOME On the main screen you can see the cabinet’s input and output: • Input: You can see a vumeter with the input level and a clip signal. • Output: You have a vumeter with the output level (0 dBu is the amp’s maximum level) You can check the compressor and control the dynamic activity.
	SETTINGS This panel allows you to change the gain, polarity, mute and the delay for the inputs. You also have the possibility of putting a high pass, changing the type of filter, frequency and order.
	FOLDER The folder screen shows you the name of the preset and its description. Using the joystick you can change the preset.
	CONFIGURATION This screen is to configurate Ethernet. You can choose automatic or manual. You can also configure the screen saver. And here you have the input selection. You can choose between analog or AES3 for channel 1 or channel 2.
	INFORMATION The last screen shows you some general information regarding the cabinet’s components. Here you can see the cabinet model, its serial number, DSP firmware and hardware versions, amp module model with hardware version, as well as the accelerometer status.

Watch the following TUTORIAL to understand how it works:
