- with dedicated software
• Go to panel control of DMS26 (Device then Add Device Panel, select DMS26, press enter)
• Open selected “Output” window (1 to 6)
• Setting Threshold is located at the bottom right and can be adjusted from - 40 to +20 dBu
The following table expresses the threshold corresponding to the nominal output power provided by the amplifier.
Values for a standard gain of 26 dB

Power below 8 Ohms Power below 4 Ohms
0 30W 60W
+1 38W 76W
+2 48W 96W

Limiter threshold
: threshold (dBu) = 20 log ( (Power (W) x Impedance (Ohms))/0,775) –amplifier gain (dBu)
Assignment of the input signals towards output signals
- with the front panel buttons
• Use “CH” button to go to the selected output
• Use the Parameter button to go to the “source” function.
• Choose source with the first knob which offers possibility between the Inp_A, Inp_B & Sum_A+B
- with dedicated software
• Go to panel control of DMS26 (Device then Add Device Panel, select DMS26, press enter)
• Open Crossover window.
• Access to the choice of the source is in the first column of the table.
Connection to a computer
Connection RS232
Many laptops do not comprise a connection series RS232. It is then advisable to use a converter USB towards RS232.
Unfortunately, few converters meet the requirements to perform correctly with the DMS26. The converters must be
equipped with chips FTDI or Prolific X (imperative version “X”).
The following onverters USB - RS 232 were tested and are satisfactory.
- Aten UC 232A (Is the one with the most updated drivers)
- Easysync US232B
- Easysync USB-COM
An 9 pins extension cable should be envisaged, in addition to the converter, because this device cannot be installed
directly on the DMS26.
