Thunder-KSP Speaker Input

either +1 –1 terminals, or +2 –2 terminals.

NL4 speakON +2 –2 terminals:
signal polarity is +2 HOT, –2 COLD.
Both NL4 speakON connectors can be used to fed the input
signal: either +1 –1 terminals and +2 –2 terminals are pass-

The terminals switch allows you to swap the internal
transducer(s) leads assignment to the speakON terminals.
