entry positions for these connectors should 
therefore be used with European models.

 Output Connectors
These two connectors  accept 2-pole or 4-pole 
Speakon connectors. See Figures 2.8, 2.9 and 
2.12 and Tables 1, 2 and 3 for connector wir-

both channels so it can be used for bridge-
mono wiring or for stereo wiring of two speak-
ers to a single Speakon connector.
