I M P O R TA N T N O T E A B O U T S P E A K E R J A C K S :

In some areas 1/4” speaker jacks are not acceptable for use on amplifiers capable of high output power levels. For this reason the 1/4” jacks on your KX-160 may be factory sealed – in such cases, use the Speakon® jack provided for connecting the ampli- fier to external speakers. Use heavy duty speaker cables terminated with the proper connectors.
