Loudspeaker Connections
Due to the DDC feature, the ES 10 has 4 output terminals per channel instead of 2. The speakon
connector is wired as follows:
Pin 1+ = “hot” or
Pin 1- = “cold” or Signal-
Pin 2+ = “DDC hot” or DDC+
Pin 2- = “DDC cold” or DDC-
For optimum performance, the amplifier to loudspeaker connections should be made as shown
in figure 3-2.
The and DDC+ (Dynamic Damping Control) terminals are linked together at the
louds terminal. The signal- and DDC- terminals are linked at the loudspeaker - terminal.
A maximum damping is obtained with these connections. If your speaker system is not prepared
for a four terminal connection, link the DDC and the signal leads at the input of the enclosure
(see figure 3-3).
