Figure 3-8 Correct way of connecting several enclosures to the ES 40
The amplifier can cope with any load of 2 Ω or higher. This means that you may connect a
maximum of two 4 Ω, four 8 Ω, or eight 16 Ω loudspeakers per channel in parallel. Linking the
loudspeakers from one enclosure to another has two major disadvantages:
1.The loudspeaker cable from the amplifier to the first enclosure conducts the current for all
enclosures, which means extra losses.
2.The DDC only works for the first enclosure.
Splitting the leads at the amplifier output terminals solves these problems (see figure 3-8). The
DDC system corrects the performance loss due to connectors, loudspeaker cables and so on.
However, it cannot prevent loss of power. So only use cables of minimal 2 x 1.5 mm
for the loudspeaker leads and 2 x 0.75 mm
For bridge mode operation, simply connect the speaker to the channel 1 output connector.
