If you don’t want to use the DDC feature at all, the DDC and the signal leads should be linked
at the amplifier output in the speakon connector (see figure 3-4). The DDC terminals can also
be left unconnected but then the performance will be less.

Warning ! Never short-circuit the DDC terminals, and never connect the  output terminal
to the DDC- terminal or vice versa (see figure 3-5). Since you are disabling the amplifier’s
feedback network, signal gain will be almost infinite. The smallest input signal will result in full
power output with the possibility of square waves damaging your loudspeakers!

Therefore, check your cables regularly. We also advice you to use special Stage Accompany
4-wire loudspeaker cable: 2 x 3.0 mm
