Dimensions and Cooling system
NOTE:
The size is 437mm inside of the device(without the cover plate and front panel).The size is around 472mm of the complete device,but a little bit different size in the different front panels.Some series with different size have not shown,please learn it in the parameter.


Tunnel through cooling system
Cold air comes in from the front panel of the equipment and forms a duct through the radiator to take the heat away and out from the rear panel of the equipment.


 


ALLDSP ALLControl 
The new D series digital amplifier also has the option to add a DSP function, Our D series DSP amplifier uses an ALLDSP system from Germany. It is suited for Windows, Mac and ios systems.

Attention: You cannot connect the unit to the network through the USB or Ethernet at the same time. You can only control the unit from one platform at the same time if you switch from one platform to another, you MUST shut down the control software at the previous platform first.
 
Local connectivity of the device to the control computer from a front-panel USB connector is also possible to download initial settings or as a fallback in case of network failure.

►Unit Window: Main Panel



Unit window shows the unit window from which all setup screens and options can be reached.Clicking the exit cross will close the software but leave the network Control program running.


Input Channel Settings Screen


Clicking on an Input channel number in the Unit window will bring up the input channel settings screen see Figure above. In this screen, individual input channels can be equalized and/or filtered.

Settings screen:
Filtering and EQ
Input channel transfer function curve
Screen expansion and legends
Input Gain, Mute
Delay, limiter, compressor
RMS compressor
 
●Screen expansion and legends
On the left-hand side of the graphical screen are four icons to help precise settings. The top Arrow icon expands the graphical screen to the size of the window.Clicking this icon again from the expanded screen expands it to the full display size. In either of the expanded settings, clicking the X-icon at the top left will collapse the graphical area to the default setting.

The T(ext) icon will place the frequency, Q, and gain values of each EQ and filter setting in the graphical screen. 

For very accurate settings of EQ or filtering you can click the Looking Glass icon.
 
●Delay, limiter, compressor
Settings for channel delay, limiter (-48 to +24 dBu), and limit release rate (10 to 100 dB/s) settings.Plus a button to enter the rms compressor menus. Channel delay can be set in a variety of distance or time units from the drop-down list.
 
●Compressor settings window
Clicking on the compressor button brings up the compressor menu.
In the compressor menu you can set the parameters of the rms compressor.You can set the threshold, attack, hold, and release time, the compression ratio and the make-up gain.Next to the controls is a VU meter that also displays the gain reduction (GR). Be sure to use the ‘Back’ button to return to the output menu.


►Crossover Settings Window


When you click X-over in the left unit window function list, most of the screen is dedicated to the controls and indicators for setting up the cross over filters as shown in Figure.

Settings screen:
●Graphical control
●Filter type
●Gain
●Delay
●Link
●Mute, Phase Invert


►Output Channel Settings Screen


As shown in the picture above, faders are shown for each of the input channels. This will allow mixing each of the input signals to each individual Output channel. Even if Input channels are set to Linked in the Unit window, it is still possible here to mix individual Input channels to an Output channel in any desired ratio. Level setting are shown numerically below each fader. The available range is from -48 dB to 0 dB. As in other screen, double clicking a fader resets it to default.

A complete control screen is available for each Output channel. The graphical area reflects the Crossover settings for the channel in addition to any equalization settings set up in this screen, and is very similar to the available settings in the individual Input channel screens.The status of an element is always reflected in the blue on/off button next to each element.

Settings screen:
●Relationship between Input- and Output settings
●Output filtering and EQ
●Output channel transfer curve
●Delay, limiter, compressor
●RMS compressor
●Change / adjusting Values
