General Set-up Instructions
Speaker Wiring
Connectors
The loudspeakers are connected via SPEAKON connectors, NL4FC and NL8FC (not supplied). A
wiring diagram is printed on the connection panel located on the back of each cabinet. The pins of
the SPEAKON sockets are identified in/out and connected in parallel within the enclosures. A
single 8-conductor cable carries all four bands required by the Alpha M3/B1/S2 system and the
cabinet connectors allow all three types of cabinet to be safely linked at the loudspeaker end. (See
Connections Diagrams at the end of this manual).
NB: The Alpha S2 back panel features only one 4-pin SPEAKON connector in order to prevent
accidental parallel connection: very few amplifiers are able to drive such low impedance loads at
the required power level.
