QUICK REFERENCE GUIDE 

 
 
 

 

 
 
 

Display 

The LCD displays preset and parameter information. The default screen is shown after start up and displays the number 
and name of the current preset on the lower line of text. When navigating around the adjustable parameters, other 
information is shown. 
 

Channel Select Buttons 

The currently selected input or output channel is shown in the top left corner of the display. Pressing the channel select 
buttons scrolls through the available inputs and outputs. If operating stereo linked the channel pair is shown. For 
example ‘CH A+B’ means both input A and B parameters. 
 

Edit Select Buttons 

The name of the edit parameter page is displayed in the bottom left portion of the LCD. Pressing the edit select buttons 
moves through the available parameter pages for the current input or output. 
 

Parameter Knobs 

Up to three parameters are shown on the display. The parameter name is shown with its’ current value below. Where 
appropriate, parameters are grouped according to function. For example the parametric equalisation page shows centre 
frequency, width and gain. Turning a parameter knob clockwise will increase the value of a parameter, turning anti-
clockwise will decrease it. Turning a knob rapidly will cause the action to ‘accelerate’, so the value changes more rapidly. 
 

Mute Buttons 

The LEDs next to the mute buttons indicate their current status. Pressing a mute button toggles between the mute on 
and off. 
 

Store Button 

The unit has 45 preset locations. To store a preset in a location, press the store button and use the parameter knobs to 
select the preset location and name the preset. Pressing the store button again completes the task. Pressing any button 
other than store during the process cancels the procedure. 
 

Recall Button 

To recall a preset, press the recall button and use parameter knob A to select the required preset. Pressing the recall 
button again will activate the preset. You will then be asked to confirm by pressing recall once more. As with the store 
function, pressing any button other will cancel the process. 
 

Limiter Settings 

In order to offer the maximum of protection, some factory presets of the DMS26 can be entered with the fixed limiting 
device with 0 dBu, limiting the power to approximately 30 W in 8 Ohms. 
It is then essential to set the threshold according to your devices.  
To do it : 
 

- with the front panel buttons 

 

 

• Use “CH” button to go to the selected output 

 

 

• Use the “Parameter” button to go to the Threshold parameter 

 

 

• Adjust with the parameter knob.
