has ¼" jack and a Speakon connector, which are
powered outputs used to connect your right side
main PA speakers.

Speaker Connections

The S4000 contain two mono power amplifiers which deliver a maximum output of 500W + 500W.
The total impedance load for each amplifier must not be less than 4 Ohms.
If you use a single speaker to the ¼" jack or Speakon connector, use a 4 through 8 Ohm speaker.
The total impedance load for each amplifier must not be less than 4 Ohms, therefore one speaker
with an impedance of 4 ohms can be connected to each amp's ¼" jack or Speakon connector (see
figure 1).
Two 8 Ohm speakers can be connected to the AMP 1 ¼" jack and Speakon connectors simultane-
ously and two more to the AMP 2 ¼" jack and Speakon connectors, for a total of four speakers. The
A/B jacks are wired in "Parallel", so the total impedance when two 8 Ohm speakers are connected is
4 Ohms (see figure 2).
