DSP configuration
DSP configurationDSP 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. |

Datasheet
The GXR-D18P is a high output bass reflex omni-directional subwoofer cabinet. Consists of 2 x 18″ (4″ voice coil).
The GXR-D18P subwoofers are specifically designed to be stacked and are very easy to use.
Depending on the configuration, the system is amplified with the GTX Series, 4-channel, extremely high power level amplifiers with outstanding, high efficiency. They come equipped with a quality FIR-DSP with high performance 96kHz DSP processing and a large IPS display with a touch panel user interface.
Advanced Audio Power Control Management has been implemented in the design of the GTX series. This enables the user to configure the division of power between the channels via the DSP enabling them to obtain maximum power through just one single channel if desired. Optional Networking AES67 and AES3 Digital inputs are also available.
