Hardware for Ionic 18S

Enclosure

The IONIC-18S cabinet is constructed from 13-ply premium birch plywood (15mm thickness) and finished with polyurea coating.

 

 

 

Internal design

The internal structure of the IONIC-18S is heavily braced for greater longevity and all parts are assembled on metal inserts with metric screws. The amplification modules & DSP are housed in a separate chamber to the drivers.

 

 

 

 

Rear panel

The powder coated steel rear panel contains all connections and houses the IONIC-18S amplification modules and DSP, is easily accessible and housed separately from the drivers avoiding excessive heat & vibration, thus delivering greater efficiency and reliability.

 

 

 

 

Grill

The ionic-18S has a heavy duty, powder coated front grille with a special acoustic rear fabric to protect the transducers against dust and dirt.

 

 

 

 

Handles

One ergonomic, die cast handle with firm internal grips is located on each side of the IONIC-18S enclosure to facilitate transport, positioning and loading of the cabinets.

DSP

DSP configuration

On the back panel 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.

 

 

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.

 

 

INFORMACIÓN

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.
