Description

The CPS-18S is a high-output, extremely powerful sub-bass element designed to be used in unison with the coaxial CPS-214 point source module.

It uses one low distortion 18″ (4″ QUATTRO in/out copper voice coil) custom speaker with FEA optimized ceramic magnet circuit and Exclusive Malt Cross Technology cooling system. It implements Exclusive NCR (Neck Coupling Reinforcement) and is optimized for band pass configuration.

The extra strong, specially designed internal wooden reinforcements reduce unwanted vibrations eliminating any noise, lowering distorsion and delivering a clear sound. At the same time, the bass port is designed with a flare to eliminate any turbulence caused by sharp edges in the sound waves path.

The 3000W Class-D amplifier with PFC (Power Factor Correction) offers exceptional efficiency with maximum system performance whilst significantly lowering power consumption. With Thermal, short-circuit and overload protections the system module delivers an outstanding sonic performance. Coupled together with our new generation, 64 bit/96KHz processor the system electronics are yet further guaranteed not only the utmost protection but the best performance.

Designed in-house by Lynx Pro Audio engineers our DSP offers the most recent advances in digital processing, delivering a linear phase & frequency response. The latest 32 bit/96KHZ AD/DA converters make the system one of the most advanced & innovative subwoofers on the market resulting in superior sound quality.

A 2.8″ IPS user interface is located on the enclosure’s back panel and has multifunction joystick control enabling the user to control, select and/or adjust parameters such as cabinet presets, gain, delay and input EQ (see user manual).

Two Ethernet ports enable the system to be controlled with the OCS platform for easier alignment, monitoring and processing of the array and together with the new Rainbow 3D prediction software delivers a complete system design tool.

The enclosure is made from premium grade birch plywood and finished with a polyurea coating for longer durability & weather protection.

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.
