Start Up Tests
When D Series drivers are switched on they execute a series of tests that check the driver’s internal
systems and also the loops that they are connected to . These tests take about 5 seconds and the
display reads “DIAGNOSTICS IN PROGRESS” whilst they are being performed .
If everything is OK the display should read “AMPETRONIC DXX-X” (where the X’s change
dependent upon the model of D Series driver you have purchased) on the top line and the name of
the driver underneath. If an error was detected then the red error light will flash and the display will
read the cause of the error . Please refer to section 10 where the error messages are explained in
detail .
Initial Setting up
D Series drivers include a test signal generator that can produce 5 different test signals: Sinewave,
pink noise, pink noise – 1K sinewave (combi 1K) signal, combi 1.6 kHz and combi 2.5 kHz.
These signals over-ride the inputs on the back of the driver . Switching off the test signals routes the
sum of the signals on inputs 1 and 2 to the loop outputs .
N .B . This driver is not stereo in that input 1 does not exclusively drive loop A and input 2 drive loop
B . The factory default settings of the driver have both input gains set to -80dB which is effectively
off .
