connecting outputs

All models have two output (speaker) connections per channel. Cables can be connected with banana plugs, spade lugs or bare wire to the five-way binding posts.The preferred method is connection via the Speakon® connectors.

Output terminals are hazardous live and the external wiring connected to these terminals requires installation by an instructed person or the use of ready- made leads or cords.
